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.
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.

• 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

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.”
