I&T -> Commissioning − I&T planning summarized: • • • LCA-40 Integration and Test Plan LCA-283 Camera Verification Test Plan LCA-10148 Survey and Alignment Plan − Documentation • e. Traveler summaries, NCRs, as built docs, etc − Characteristics Data Delivered with the Camera • Information delivered to Data Management • Iterated several times and under change control, LSE-130 • Details of vendor test data will be added as they are determined • Includes: • As-built position information from I&T • FEA distortion models • Sensor and optics characteristics (from test plans) • Filter and lens vendor test results • Optical model as-built inputs/updates to support integrated observatory modeling • Shutter motion profiles and shadowing model as a function of position measurements • Thermal model to interpolate temperature measurements • Configuration LSST 2016 • Aug 15 -19, 2016 8

Summary of inputs from camera team − Camera Management • Need to clearly understand colors of money ($$$) and properly manage boundaries. 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? • e. Traveler 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) • L 3 integrated at delivery • L 1/L 2 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 Com. Cam • Commissioning systems (2) at summit LSST 2016 • Aug 15 -19, 2016 11

Summary of inputs from camera team − CCS • Pathfinders • Need CCS prior to Com. Cam • 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 Com. Cam 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 L 1/L 2 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. LSST 2016 • Aug 15 -19, 2016 13

LSST COMMISSIONING: CAMERA TIME FRAMES LSST 2016 • Aug 15 -19, 2016 14

Time Frames: Camera Perspective − Pathfinders for CCS and DAQ • ~2018 − Com. Cam era • Early 2019, merge T&S/Cam hardware • Mid 2019 to early 2020 – On telescope • Refrigeration pathfinders − Camera Ready at SLAC • Feb. 14, 2020 − Camera on summit (camera maintenance area) • Spring/Summer 2020 − Camera on telescope! • Fall/Winter 2020 − (Dates approx. from gantt charts) LSST 2016 • Aug 15 -19, 2016 15

Time Frames: Camera Perspective − Pathfinders for CCS and DAQ • Needed before Com. Cam arrives • Discussion LSST 2016 • Aug 15 -19, 2016 16

Time Frames: Camera Perspective − Com. Cam era • Add missing scope in LSE-199 • Or at least clarification of scope and responsibilities • @SLAC • I&T scope @ SLAC • Union of I&T scope and T&S scope @ SLAC • Unified testing @ SLAC • Shipping • On Summit • Testing on floor before going on telescope • In mass simulator on telescope • Parallel refrigeration pathfinder in mass simulator LSST 2016 • Aug 15 -19, 2016 17

Time Frames: Camera Perspective − Camera Ready at SLAC Camera I&T done Pre-ship/Acceptance review (3. 08. 04) Camera into/next to shipping container (3. 08. 05) Camera project (DOE MIE) done! 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
