August 9 - Imagine you’re driving a ridiculously expensive sports car, and you have to park it in a space so tight there’s only an inch of clearance between you and the cars on either side, which, incidentally, are also ridiculously expensive sports cars. Feel the pressure? The Integration and Testing (I&T) Group at SLAC National Accelerator Laboratory know this pressure well; they’re currently facing a comparable challenge as they work to integrate the 21 science rafts and the 4 corner rafts into the LSST Camera cryostat grid.

These rafts are the platforms that support the LSST Camera’s charge-coupled device (CCD) sensors; each science raft holds a 3x3 square of sensors. A raft and its accompanying tower of electronics comprise a raft tower module (RTM), and this whole structure is what must fit into each space in the cryostat grid. The widest part of an RTM is the CCD sensor, and it’s also the most delicate. In the assembled focal plane, only 500 microns of clearance exist between adjacent CCD sensor edges. For perspective, a human hair is about 75 microns in diameter, so you can imagine how fitting these pieces together so closely requires remarkable precision. 

The SLAC I&T team is using a specially-designed machine called the raft integration mechanism to carefully install the rafts into the cryostat grid while avoiding any contact between the sensitive CCD sensors. The raft integration mechanism (also called the integration gantry) is pictured below on the left. The cryostat assembly has been mounted on a test stand called the Bench for Optical Testing (BOT), which allows it to be suspended in the air above a staging platform. The cryostat is facing down to protect the CCD sensors from damage and particulates, so each RTM is lifted into the cryostat assembly from below. The RTM is placed on the platform, and attached to the arm of the integration mechanism. The raft integration mechanism arm has 648mm of travel up and down; enough to pull the RTM all the way up into the cryostat grid.

After the RTM’s protective features are removed, including a cover that protects the CCD sensors, the RTM is lifted by the arm towards its designated space in the cryostat grid. An I&T team member observes carefully from above the BOT to visually confirm that the RTM is on track. As the RTM gets closer to the cryostat grid structure, four cameras (pictured below, right) are installed on the base platform. Facing upward, the cameras' telecentric lenses record the RTM's position as it travels the last critical distance towards integration. A team member monitors the video camera footage, and another makes any necessary corrections to the raft integration mechanism arm’s position. 

Travis Lange, Lead Mechanical Engineer for the I&T Group, reports that to date the group has completed many cycles of successful installation and removal of Mechanical Test Rafts (MTRs), which don’t have functioning sensors, from a mockup of the cryostat grid. The photo above shows multiple MTRs installed in the mock-cryostat. The production cryostat grid was recently completed and has been installed in the BOT frame; next steps include installing and removing Mechanical Test Rafts from the cryostat grid, and then testing installation and removal of two Engineering Test Units, which are full science rafts but with sensors that won’t go in the final Camera. After a few more months of testing, and after additional work on the cryostat assembly is completed, the I&T team will be prepared to install the real science rafts. Travis estimates this work will begin in early 2019.

Financial support for LSST comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded LSST Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA). The DOE-funded effort to build the LSST camera is managed by the SLAC National Accelerator Laboratory (SLAC)

PRÓXIMAS REUNIONES con LA PARTICIPACIÓN DE LSST

July 27, 2018 - The Education and Public Outreach (EPO) team hosted a teacher focus group in Tucson on July 16-18. This was the second in a series of events to collect feedback from educators about the formal education products being developed by the EPO team. Twelve teachers with students in advanced-middle school through college attended the focus group; their comments and survey results will inform the EPO team as they continue to refine the online resources provided for teachers during LSST Operations.

The central priority of the meeting was to present teachers with the first of six themed investigations being developed by the EPO team, using an online notebook platform. The teachers were given the opportunity to interact with a prototype notebook, analyzing a data set to answer questions about star properties as their students would in the classroom. A discussion followed in which teachers commented on how they might implement the activity, which elements of the investigation worked well, and which could be improved.

In addition to using the science notebooks, teachers also reviewed instruction and assessment videos, teacher guides, and other prototyped resources developed by the EPO team during the last year. A discussion period also followed each segment in which teachers were invited to give verbal feedback. EPO Evaluation Specialist Ellen Bechtol also guided the teachers through an online survey to capture written opinions and comments throughout the workshop.

The success of the meeting was the result of hard work by the entire EPO team; to get useful feedback it was necessary to provide teachers with significant investigation content on a technologically stable platform. LSST Education Specialist Ardis Herrold remarked that the meeting was incredibly productive, and will help the team with a lot of impending decisions that need to be made. "We have finite resources, and we obviously can't do everything," she commented at the workshop's conclusion. "But having a better understanding of what teachers want--and what they need--makes it easier to establish our priorities and move forward."

Additional photos from the event are available in the LSST Gallery.
 

July 16, 2018 - In Paris, France, the Filter-Exchange team is currently performing combined testing of the prototype filter exchange components at the Laboratoire de Physique Nucléaire et de Hautes Energies (LPNHE). The filter exchange is the result of the collaborative work of five French IN2P3/CNRS laboratories.

There are three components in the filter exchange system: the auto-changer, the carousel, and the filter loader. The prototype auto-changer and carousel (featured in the photo above) are being used to test the many individual components of the system and how they perform in the assembled unit. Addressing challenges with this prototype system will greatly reduce issues encountered once the production system is assembled.

The LSST Camera has a total of six filters, with five filters in the camera at one time. During nightly observations, the auto-changer will efficiently swap the filter in place over the lens with another filter from one of the five storage positions on the carousel. The system has less than two minutes to change a filter, so the auto-changer has been designed to move smoothly and quickly. The graphic at this link shows the action of the auto-changer.

The filter-exchange system is compact but robust; 200kg (≈441lbs) of weight is moved whenever the carousel rotates. The filters self-clamp into their storage positions, but a mechanical action is required to release them. The clamps hold the filters securely, but not too tightly--in case of seismic activity the delicate filters need a bit of "wiggle room" to reduce the risk of damage.

Only five of the Camera's six filters will be used in the Camera on any given observing night, but during the day, the filter loader can exchange one of these filters for a different one. The filter loader doesn't have to work as quickly as the auto-exchanger, but it must still handle the delicate filters carefully. Additionally, it's important that the inside of the filter loader be kept clean and free of dust. Two loaders and two auto-changers will be built; if one requires maintenance the other can be used so there's no disruption in activity.

In a separate clean room at LPNHE, the production carousel is being assembled and will soon be attached to the back flange of the Camera, which was shipped to Paris from the SLAC National Accelerator Laboratory in June 2018. The combined unit will be returned to SLAC in January 2019, ready for Camera integration.

PROJECT & SCIENCE NEWS - Noticias del Proyecto & Científicas 

Registration for LSST 2018 is now closed. Approximately 320 people registered for the meeting, the highest attendance number to date. The block agenda for the meeting is available at this link.

The Camera team reports a major project accomplishment: in late June, construction of the Cryostat assembly was completed at SLAC. The assembly was moved to the SLAC IR2 Cleanroom Facility, where the Cryostat pump plate was attached, and the assembly underwent early vacuum-testing. A photo of the completed Cryostat is available in the LSST Gallery.

The Camera team received the last sensor to be provided by the UA Imaging Technology Laboratory (ITL) at Brookhaven National Laboratory (BNL) on July 12. The second sensor vendor, which is providing the balance of sensors required by the project, has fewer than 25 sensors to complete. At BNL, assembly of science-raft tower modules (RTMs) using these sensors is moving quickly toward completion of 21 production units by the end of 2018.

In June at Arizona Optical Systems (AOS), the L2 lens for the LSST Camera successfully completed a bonding process that attached the lens to the pads that will mount to the composite ring of the L1-L2 assembly. The assembly is the mechanical structure that holds the L1 and L2 lenses, maintaining the correct separation between the two. The L1 lens is at REOSC in France, waiting for Broadband Anti-Reflection (BBAR) coating. Photos of the L2 lens at AOS are available in the LSST Gallery.

Following vacuum-integrity testing, Thales SESO (TSESO) delivered the L3 Camera lens test window to SLAC IR2 in late June. The test window is an optical flat that stands in for the L3 lens during RTM testing using the Bench for Optical Testing (BOT) at IR2. The BOT enables the Integration and Test team (I&T) to install RTMs within the Cryostat and to do follow-on metrology and electro-optical testing.

From Spain, a new video in the LSST Gallery shows the Telescope Mount Assembly (TMA) rotating on its azimuth at full speed (10.5 degrees per second). This successful test indicates that TMA team will soon be ready to start verifying the most stringent performance requirements in preparation for disassembling and shipping the TMA to Chile later in 2018.

LSST 2018 Project and Community Workshop

August 13-17, 2018 - Tucson, Arizona

The deadline to register and book a hotel room is July 9th. 

It'll be an exciting week of face-to-face interactions during this critical time! As integration of hardware and software brings us closer to having a functioning telescope system, commisioning is ramping up and the LSST Community prepares for Science.

Community Workshop on the Impacts of Blending on LSST Science

A workshop on the impacts of blending on LSST science will be held as an integrated part of LSST 2018, on Tuesday through Thursday, August 14 - 16, 2018. The workshop will focus expertise across the LSST community on assessing our current understanding of blending issues. 

July 2, 2018 – LSST@Europe3 drew approximately 150 participants to Lyon, France, on June 11-15, for presentations, tours, and informal opportunities for networking between members of the LSST Project and the European science community. Zeljko Ivezic, LSST Project Scientist and co-chair of the meeting’s Scientific Organizing Committee, enthusiastically noted the high level of participation from younger scientists at this meeting, an indication that excitement for LSST is building among those just beginning their science careers.

LSST@Europe3 featured formal plenary talks as well as informal science collaboration workshops and data sprints, in which participants explored processes for querying large astronomical data sets. Highlights of the meeting included the development of new science cases for LSST, reports on the detailed preparations for LSST science that are underway in Europe, and new suggestions for modifications of the LSST observing strategy.

Participants also had the opportunity to become more familiar with LSST's Science Platform during a tutorial of the LSST software stack, and to contribute to discussions about synergies between LSST and other data-driven projects like Gaia, Euclid, and 4MOST.

Tours of the nearby IN2P3 Computing Center (CC-IN2P3) and the Advanced Materials Laboratory (LMA) facilities were also offered during the week. CC-IN2P3 will process 50% of LSST’s raw data in preparation for annual data releases, and will host a copy of both raw and reduced data (images and catalogs) for the lifetime of the LSST Survey. LMA, which has been involved with LSST since 2007, is developing an optical bench to measure the spectral response of the LSST camera filters.

LSST@Europe3 was the third in a series of meetings intended to promote European participation with the LSST Project; the next meeting will take place in Rome, Italy, in 2020.
