LSST Commissioning: Camera Time Frame

Commissioning Planning Time Frame: Camera Camera commissioning scope estimate - non-MIE (2*) Camera shipping plan (1) Camera on summit re-verification plan (2) Camera summit facility build-out plan (2) Detail tests with ComCam for Early System AI&T (same 2) Detail Science Camera tests for Full System AI&T (3) Non-MIE Camera supplied hardware design, costing and BOEs (10 in parallel with above) This is list from Chuck with number of weeks allotted to get it done in parenthesis

Commissioning Planning Time Frame: Camera Camera commissioning scope estimate - non-MIE (2*) Camera shipping plan (1) Camera on summit re-verification plan (2) Camera summit facility build-out plan (2) Detail tests with ComCam for Early System AI&T (same 2) Detail Science Camera tests for Full System AI&T (3) Non-MIE Camera supplied hardware design, costing and BOEs (10 in parallel with above) Bold is fairly well covered in I&T scope (but full team feedback needed) Regular is maybe covered at some level by I&T and SE Faint is covered no where in MIE as far as I can tell.

(I’ve started collecting info but have a lot more to do). 3.06.03 Filter Exchange System 3.06.02 Shutter 3.07.02 DAQ 3.05.03 L1-L2 Lens Assembly 3.07.01 Camera Control System

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 eTraveler 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

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? 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. Handling colors of money is very important to get right.

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

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* 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

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 Need DAQ prior to ComCam Calibration telescope? Network issues/boundaries (summit, summit to base, etc)

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.

LSST Commissioning: Camera Time FrameS

Time Frames: Camera Perspective Pathfinders for CCS and DAQ ~2018 ComCam 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) What did I miss? These are mine based on my vision (with a lot of discussion with others)

Time Frames: Camera Perspective Pathfinders for CCS and DAQ Needed before ComCam arrives Discussion Note to discuss more

Time Frames: Camera Perspective ComCam 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 What did I miss?

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. Re-verification 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.” What did I miss?

LSST Commissioning: Logistics and Existing Plans

9 3? Logistics of shipping I&T fixtures prior to camera indicates that some fixtures arrive with camera thus requiring time to install fixture before reassembling camera.
