A Review of the Camera integration and test process plans took place this week at SLAC.  This technical and programmatic review was to assess the overall integration process flow as well as the planning supporting the work and designs for the equipment, software and databases to be used.

March 23rd was “A Day in the Life of LSST” with everyone working on LSST encouraged to take an interesting picture of something representative of their work to chronicle the LSST construction.  The 150+ images received will be assembled into a slide show highlighting the many aspects of LSST construction as well as the people doing the work.

LSST Data Management has started optimizing and improving techniques, processes and tools for communicating inside the team as well as with the outside world. A technical note will be released shortly.

The LSST Science Advisory Committee (SAC) met on Monday, March 21.  The main topic of discussion were plans for how alerts would be distributed to the community, and how many data releases would be kept spinning at any time.  Minutes are available at the LSST SAC website.

The following individuals have ended their terms on the LSST SAC: Harry Ferguson, Chris Hirata, Lisa Hunter, Bhuvnesh Jain, Rachel Mandelbaum, Dante Minniti, and Ricardo Muñoz.  We thank them for their hard work on the SAC.  Recently joining the SAC are Timo Anguita (U. Andres Bello, Chile), Marla Geha (Yale), Charles Liu (AMNH), Nelson Padilla (U. Catolica de Chile), Anže Slosar (Brookhaven), and Risa Wechsler (Stanford).  We look forward to their involvement and input!

S. Jacoby traveled to La Serena, Chile last week to participate in the second annual Chile-US Astronomy Education Outreach Summit with more than 60 other representatives of astronomical and educational organizations and facilities in Chile.  The Summit involved administrators, formal and informal educators from Chile and the US, university scientists, funding agencies, the US Embassy in Chile, regional government leaders, and representatives from the professional scientific observatories as well as the smaller community observatories and the astrotourism industry in Chile.  Products of the summit include the construction of a network of astronomy educators, and a “roadmap document” to help guide and promote future collaboration and coordinated of astronomy EPO activities in Chile, and between its international partners. A final draft is expected sometime in May of 2016.

J. Becla, interim Project Manager for Data Management (DM), reports that members of the DM team traveled to NCSA last week for a productive session on data processing system construction planning. 

Members of the Telescope & Site team are in Chile this week, meeting with the Telescope Mount Assembly (TMA) prime contractor Empresarios Agrupados and summit construction contractor Besalco Construcciones.  The work includes preparing a plan to integrate the TMA into the LSST facilities building, and finding space around the main telescope in which to safely maneuver the multiple pieces of steel. 

CAID Industries in Tucson has completed the floor of the M1M3 mirror cell and is ready to install the hardpoints, which will provide additional support for placing the mirror in the cell.

PERSONNEL NOTES

This week LSST welcomes several new people to the project team:

  • Project Science Analyst Melissa Graham has joined Zeljko Ivezic’s group at UW where she will support Data Management (DM) activities from a science perspective.  This includes leading studies of DM plans and deliverables, providing feedback to the pipeline design, and producing user-facing papers describing the DM data products for the broader astronomical community.
  • Pim Schellart has joined Jon Swinbank’s group at Princeton as a scientific software developer.  Pim’s duties will include development of the low-level, high-performance primitives used to construct the DM software stack.
  • Brian Johnson has joined the Telescope & Site group on a temporary basis, using his engineering experience with manufacturing, inspection and design of military ordnance to support engineering documentation of the M1M3 mirror cell & support system effort.
  • Cindy Wang has joined the Data Management group as application developer in Xiuqin Wu’s Science User Interface group at IPAC.

As a reminder for the project team, note that today is Laurie Thomas’s last day as our Travel Coordinator.  Travelers should start to use their subsystem administrative assistant for their travel needs until Laurie’s replacement is onboard.  Thank you Laurie for your excellent service to the LSST Project.

PROJECT NEWS

We have received the Status Review report from the NSF.  Management is reviewing it before sending it out more broadly next week.  We also received the EVMS report and as we anticipated, we have some actions but there were no critical findings. Our next status review will be in August during the All-Hands Meeting and will be a joint NSF/DOE review.

There is lots of activity on Cerro Pachón – lower enclosure excavations have been approved; plates from the dome manufacturer in Italy have arrived on-site; and the TMA team from Spain will be visiting the site in Chile to start integration planning.

The mirror reflective coating system contract has been signed by AURA and Von Ardenne in preparation for a kickoff meeting in April.  The DM transition leadership has started site visits with the distributed team starting with SLAC and NCSA this week.

Evacuation of exterior pier for LSST

The construction crew on Cerro Pachón is making room for a shipment of 16 sections of steel track (embedded plates) which will sit on top of the lower enclosure pier and support the wheels that rotate the dome structure. The “lower enclosure” pier is the exterior pier (its excavation effort is almost done…see the trough in the accompanying image). The Telescope Mount Assembly (inner) pier is the one that just got poured during the recent all day/all night effort.  The vertical rebar is the soon to be concrete cylinder which will go up almost 15 meters.

M1M3 mirror cell vacuum boundary vessel shown from rear.

Since its completion in January 2015, the LSST M1M3 mirror has been in storage in Tucson awaiting completion of the mirror cell.  When the cell is complete, it will be joined to the M1M3 mirror for additional testing at the University of Arizona’s Richard F. Caris Mirror Lab.  The two pieces will ship separately to Chile and then be reunited for the duration of the LSST ten-year survey from Cerro Pachon.
This image shows the continuing progress at CAID Industries on the fabrication and assembly of the mirror cell weldment. Here is the vacuum boundary vessel as viewed from the rear (note the rear access door). It is undergoing helium leak testing of the welded joints to confirm the connections are fused to hold a proper vacuum during mirror coating operations.  The mirror cell is scheduled for completion in mid-2016.

Project Manager Francisco Romero is shown here standing on the material used for the azimuth bearing track assembly with the circular tracks that support the elevation bearings to his left.

Telescope Mount Assembly (TMA) subcontractor Asturfeito in Spain has begun to produce the circular steel tracks for the elevation hydrostatic bearings.  Project Manager Francisco Romero is shown here standing on the material used for the azimuth bearing track assembly with the circular tracks that support the elevation bearings to his left.  Two tracks will be stacked on each side of the telescope in the central structure to support the elevation trunnion bearings.  To Francisco’s right, note the plasma cutter’s glowing arc as it is used to cut steel plates for additional azimuth track sectors.

Telefonica (Chile) workers laying the fiber optics cable from the Vicuna to Ovalle en route to Santiago. LSST will use this fiber to connect La Serena and Santiago at 100 Gbps..

In Chile, dedicated fiber-optic lines will connect the Cerro Pachón summit and base site in La Serena, but additional networks are required to provide 100Gbs connectivity LSST requires from La Serena to Santiago and onwards to the USA. As part of a larger effort to improve network redundancy and connectivity, the National University Network (REUNA) is leveraging an initiative by the three major telecommunications providers in Chile to provide fiber-optic links up the Elqui Valley, which adjoins the AURA property on which LSST is being built. Two contracts were signed this week to install the network fiber optic cables; REUNA will provide connectivity from La Serena to the gate at the boundary of the AURA observatory property, and Telefonica will provide required redundant high speed connectivity from the gate to the summit on Cerro Pachón.
