A draft of the LSST Operations Proposal is now in the hands of 19 external red team reviewers. The review team’s reading period has ended, and feedback will be discussed with Project leadership at a face-to-face meeting on June 7-8.

A joint teleconference between the Project Science Team and the chairs of Science Collaborations was held on May 30. The main topic was “LSST Plans for Cadence Optimization.” Slides are available at this link, and the audio recording is can be found here.

The M1M3 Cell Integration Readiness Review took place on May 23rd. The review agenda focused on the status of the mirror support components, the sequence of integration, and a summary of upcoming testing activities. The individual component tests will be done at NOAO before moving to CAID to begin the system integration and testing phase with the M1M3 Cell.

Members of the Telescope & Site team traveled to Harris in Rochester, NY May 30-31 for the Secondary Mirror (M2) Cell Assembly and Optical Test Review. The agenda focused on the status of recent testing, the status of demonstration work with mirror support hardware and the surrogate mirror, and a summary review of the planned optical testing campaign. Mirror and Cell Assembly integration is planned in late June to support the first light optical testing in July.

The Education and Public Outreach (EPO) team conducted a workshop on June 1-2 to discuss topics including data rights; interactions between EPO, Data Management (DM), and NCSA; workflow of citizen science projects; and user interfaces.

The camera team reported achievement of a milestone: the acceptance of the first Raft Tower Module (RTM) that will be part of the camera’s focal plane. Two additional RTMs are in progress.

This week’s construction photos from Cerro Pachón show that the Ash Dome for the Calibration Telescope has been completed and is awaiting installation.

Leica AT-930 Laser Tracker Unit

June 2, 2017 - Members of LSST’s Primary/Tertiary mirror (M1M3) integration team recently completed training on the Leica Absolute Laser Tracker AT-930, a sophisticated tool for collecting precise measurements in three dimensions. The laser tracker will be used for a multitude of tasks associated with M1M3 integration, including accurate positioning of static supports and wedges for hardpoints.

The laser tracker tool has three main components: the laser tracker unit (featured in the accompanying photo), a series of targets called spherically mounted retroreflectors (SMRs), and a software tool that gathers angle and distance measurements using a laser beam emitted by the unit and reflected back from an SMR. If the SMR moves, the unit swivels to track it, taking measurements as it goes. The measurements recorded by the laser tracker are precise within .001 inches, or ¼ the width of a human hair, and up to 1000 measurements can be taken per second.

The M1M3 telescope mirror will have twelve SMRs positioned on towers around its outer edge, and the laser tracker unit will ultimately be located in the mirror’s central hole (although during testing and integration the unit will be moved around as necessary to enable line-of-sight measurements). The laser tracker will be used to integrate first with the surrogate mirror at CAID Industries, and then the glass mirror at the Richard F. Caris Mirror Lab. The laser tracker will be shipped to Chile separately from the mirrors and then will be reinstalled to help locate and test the surrogate mirror, and finally the glass mirror, in the telescope on Cerro Pachón.

SMRs installed on the telescope’s Secondary mirror (M2) and camera will enable the laser tracker to align the telescope’s entire optical system with a programmed series of measurements. These measurements will continue throughout telescope operations and will help detect when adjustments to the mirrors are needed.

The laser tracker, which has been informally described as “magic” and “like something out of Star Wars” by its users at LSST, makes quick work of taking three-dimensional measurements across long distances, as long as it can send and receive an unbroken light beam. It’s an invaluable tool when working with a telescope mirror 27 ft (8.4 m) in diameter!

5-26-17 - Work on the Telescope Mount Assembly (TMA) by subcontractor Asturfeito in Spain is progressing rapidly. An auxiliary second level platform has been installed, providing access to the azimuth floor. In addition, azimuth radial bearings have been placed and vertical seismic stops have been trial fitted. Currently, the plan is to float the azimuth structure on the hydrostatic bearings in July, which will be the first time the base of the TMA supports the full structural load. Achieving this milestone will allow the Telescope & Site team to start doing balance calculations and planning rotational tests of the TMA.

 

Additional photos of recent progress are available in the LSST Gallery.

PROJECT NEWS - Noticias del Proyecto

Mark your calendars for the LSST 2017 Project and Community Workshop, which will take place the week of August 14th in Tucson, AZ. The workshop agenda will include Project topics, suggestions from the Community, and unstructured time for you to set up your own meetings. Registration will open by next week. We look forward to seeing you at #LSST2017!

Highlights of footage taken by the multimedia team that visited Cerro Pachón in March have been edited into a short video that shows the current status of construction at the telescope site. The video was distributed widely throughout the project, posted on LSST’s public website, and posted to social media.

Two major winter storms swept through Cerro Pachón last week, leaving behind some road damage, more than 20 inches (51 cm) of snow, and a (manageable) impact on the construction schedule.  More information and pictures here.

The Project Science Team held a face-to-face meeting in Seattle, May 8-9, 2017. Discussion centered on the progress of all subsystems, with special attention given to updated Data Management construction plans.  At this meeting:

  • Colin Slater, a member of the Data Management Subsystem Science Team, presented a study of the impact of heterogeneous sensor array on image differencing performance. The study concluded that all effects can be mitigated with processing algorithms.
  • Eric Bellm, the Science Lead for Level 1 science pipelines, described the upcoming Zwicky Transient Facility and how it will be used to test the LSST Alert Distribution pipeline.

Lead Systems Engineer Brian Selvy, Systems Scientist Chuck Claver, and Telescope & Site Technical Manager Shawn Callahan traveled to Spain during the first week of May to review test and verification procedures for the Telescope Mount Assembly (TMA). They also went over functional tests of the cable wrap assembly and the primary/tertiary mirror (M1M3) cover. The TMA is scheduled to undergo final pre-shipment testing in September, after which it will be disassembled and shipped to Chile.

The crew at Harris in Rochester, NY is making great progress on closed-loop control of the 3.5 meter secondary mirror (M2) Assembly. The full-size M2 surrogate mirror was placed in the M2 turnover cart for rotation testing earlier this month, with the crew working to test and optimize the mirror support system to ensure it will protect the real glass mirror. LSST’s M2 is currently the largest secondary mirror system in the world, as well as Harris’ largest manufactured optic to date.

LSST Project / NSF / AURA

May 19, 2017 – As summer starts to heat up here in the north, a major winter storm swept through Cerro Pachón in the southern hemisphere this past week, dropping nearly 16 inches (40 cm) of snow on the summit. Site Manager Eduardo Serrano was able to access the summit after the storm to provide photos of the snow blanketing the construction site. The snow was preceded by significant rain which washed out sections of the road, causing problems for trucks and staff-transporting buses. The same front also brought heavy rain to La Serena, dropping 8 inches (20 cm) of rain in just a couple of days, which is the area's usual annual rainfall. 

The storm’s impact on progress on the mountain is manageable, though costly in time. EIE and Ash Dome (the Auxiliary Telescope dome provider) were both off the mountain for about 4 days, but have since been able to return with 4x4 vehicles to clear snow and restart their work. The impact is more severe for Summit Facility contractor Besalco, who will not have access to transport workers and truckloads of roofing/siding materials until about next Monday—an anticipated total work stoppage of about 11 days. Besalco does have small crews back on site, clearing the snow and drying things out so they can get back to work efficiently when they have adequate safe access. 

Yesterday, another storm hit the mountain on the heels of the first one! It remains to be seen how much further complication and delay in site access it will cause. You can watch current weather conditions on the summit webcam.
