Create BOEs and resource loaded schedule. − Camera Systems Engineering • While camera fully verified at camera preship review questions will (almost certainly) come up during commissioning • What role is needed from camera SE during commissioning? • eTraveler transfer of knowledge? NCR handling? − Sensors/Science RAFTs • Transfer of fixtures from BNL to LSST? • Transfer/maintenance of knowledge? • On sky sensor data/performance evaluation. LSST 2016 • Aug 15-19, 2016 9 Summary of inputs from camera team − Corner RAFT* • Like SR only digital access at commissioning • Wavefront data and guide data! − Optics • All the filters will be fully characterized by the vendor by direct measurements on the actual optics across the entire aperture. r-filter, at least, also well tested at SLAC. • Float indicates all filters tested at SLAC but possible summit work needed (CCOB thin beam at summit is currently planned) • Optics handling expertise at LLNL needs transfer to camera I&T and commissioning (not just a piece of paper with procedure) • L3 integrated at delivery • L1/L2 assembly (likely) reintegrated and aligned in Chile LSST 2016 • Aug 15-19, 2016 10 Summary of inputs from camera team − Shutter • • • • Well tested at I&T prior to delivery Shutter swaps at summit during commissioning? On sky performance input/feedback First shutter refurbish as part of commissioning? − Filter exchange* • • • • Well tested at I&T prior to delivery Autochanger swaps at summit during commissioning? On sky/telescope input/feedback First autochanger refurbish as part of commissioning? − Cryostat/refrigeration* • Pathfinders during ComCam • Commissioning systems (2) at summit LSST 2016 • Aug 15-19, 2016 11 Summary of inputs from camera team − CCS • Pathfinders • Need CCS prior to ComCam • More than any subsystem (I think) CCS will be asked to add many things not in their original list of requirements. Significant manpower needs during commissioning. • Calibration telescope ? − DAQ • • • • Pathfinders Need DAQ prior to ComCam Calibration telescope? Network issues/boundaries (summit, summit to base, etc) LSST 2016 • Aug 15-19, 2016 12 Summary of verbal inputs from camera team − I&T • I&T ends with camera ready to ship • I&T has scope (3.08.05) to design, build or design/build shipping container for camera • But not all the other things that need to ship. • Nominal plan has been to reuse the L1/L2 shipping container from Optics/Ball Aerospace and ship rest of camera as one piece • Filters back in their shipping containers • Commissioning must cover shipping costs • All of camera I&T goes to Chile • Fixtures and a-frame crane for clean room in I&T budget • Alumalift, RAFT level test stands, computers • Everything else? (tools, clean room gear, etc) are not.

Ship camera • Ship fixtures • Ship test stands, tools, etc • Transfer verification data, procedures, etc − “Commissioning activities involving the Camera begins with shipping from SLAC to Chile and re-verification on the Cerro Pachon summit. Reverification activities of the Camera will be lead (led) by DOE personnel, but coordinated through the Commissioning team and plan. These activities are currently scheduled to start February 14, 2020 with a Camera Pre-Ship Acceptance review at SLAC.” LSST 2016 • Aug 15-19, 2016 18 LSST Commissioning: Logistics and Existing Plans 9 LSST 2016 • Aug 15-19, 2016 3? 20 Receiving the Camera from SLAC Camera Shroud installed as protection for auto changer L1-L2 removed These slides from Joint Technical Meeting: Santa Cruz 2016.
