Environmental Test Logistics Planning
•
•
Still in the early stages of logistics planning
Major issues at-hand (in rough order of decreasing impact)
– Cleanliness and contamination control: the A-59 high and test facilities are NOT clean
rooms  started working on contamination issues with GLAST contamination control
lead
•
•
–
–
–
CPT’s and LPT’s are still a not fully defined  final definitions of these will impact test
durations (see charts to follow)
Defining required pre-test checking/test runs of LAT EGSE and facility data acquisition
system  this impacts the off-critical path schedule and drives need dates for EGSE and
facility systems
System safety and flight hardware protection
•
•
•
What are controls needed for fully-integrated LAT
What are protocols that need to be implemented at NRL to meet these controls
Mechanical: hoisting and rigging requirements per LAT req’s from SLAC and NRL policy
Electrical: once power and conditioning needs are understood, we will address protections
– Personnel protection, access, and workspace needs and availabilities: not started
Staffing plans (see charts to follow)
– Started putting together personnel list for each test
– Staffing plans are less well understood: these will combine personnel lists with test
schedules based on the tests scoped in the Test Plans

LAT Level CPT Time Estimate
•
LAT Level Comprehensive Performance Test (CPT) Time Estimate
– Estimate is 90.5 hrs of test time
•
•
•
Does not include assumptions for overhead
Does not include SVAC runs
Basis of Estimate
– Single tower test run time actuals
•
•
•
–
–
–
Identified LAT Level test cases that will sell all requirements and validate all functions
Engineering judgment was used to estimate the time required for each test case
Assumes a high degree of parallel testing of the Detector Subsystems
•
•
–
Unfortunately these actuals may or may not apply since there is uncertainty as to the effect of
testing multiple towers in parallel
Data will not be available on parallel tower test until 4 Tower testing (late May – early April)
Data only available for CAL and TKR testing
I&T has taken this as a requirement and is currently working on a solution to make this happen
Will have a better idea that parallel test of the Detectors is feasible by 4 Tower test
Assumes Flight Software tools are used (Config files, LCI, Event Handling) to conduct
almost all tests

QA Support Plans
•
•
•
QA support of all testing and operations at NRL will largely be treated as an extension of LAT
work done at SLAC
– This ensures that environmental testing dovetails with the current QA dataset and
protocols already in use for LAT integration
– It avoids the need to develop a separate system using NRL procedures
QA personnel
– SLAC will provide day-shift QE support on the floor at NRL for the duration of the test
program
– SLAC will provide on-call swing-shift QE support from SLAC, with pager access to offduty day-shift QE as-needed
– LAT will augment this as-needed (especially during T-Vac) with NRL/Swales QE’s
– Once the test schedule solidifies, this plan will be refined
NCR/MRB processes
– The online SLAC NCR database will be used for all non-compliance reporting at NRL
– The MRB process will work similar to integration MRB’s
•
Scheduled MRB’s: there will be recurring MRB’s to handle non-critical NCR’s (e.g.: those related
to test set-up)

Summary
•
•
•
Most of the key logistics issues need to be worked still
Once Test Plans are mature, test durations will be scoped and much of the staffing plans will
then be developed (ECD: mid-June)
Many of the operations-level logistics will be worked over the summer after the final designs
and configurations of the tests are in place
