IFCT Role in Functional Tests (Larry W.)
• IFCT is responsible for helping to design/define and implement
I&T functional tests on the subsystem and LAT level (see Pat’s
presentation) with major input to LAT-MD-02730.
• The test scripts used in the functional testing will actually be
implemented by the I&T online department with guidance from
LAT-MD-02730 and IFCT. The test scripts will be placed under
configuration control by I&T online.
• The test procedures will be owned and configuration
controlled by IFCT.
• All I&T testing of flight hardware will be performed by IFCT
department electrical technicians and engineers who have
been trained in their use.
• IFCT will need major assistance from the subsystems in
helping to interpret the results of the tests (pass/fail with
report). Particularly, in the case of fail (see SVAC role slide 4).

SVAC LAT Build Data Analysis Role (Eduardo)
• There are two SVAC data analysis efforts that support the LAT build
and test and both use the same test data
– Analysis of “Pass/Fail” test data of the flight hardware relative to
an established baseline (See previous manpower chart slide 3).
– Determine hardware baseline and calibrations
– Results due with hours or, at most, a day (TBR)
– I&T, SAS and Subsystems effort, e.g., CPT test offline.
– Analyses of data from the flight instrument in various stages of
completion, which assume a well understood baseline and
calibrations (LAT wide collaboration effort).
– Uncover subtle hardware problems
– Apply SAS reconstruction algorithms to real data
– Results due in 2 to 3 weeks after data taking (TBR).

I&T/SVAC Department Meetings (Eduardo)
Date
: Weekly (Friday)
Location : SLAC , Group C conference Room, B84
Goal
: Prepare for data analysis of pass and fail tests and instrument data analysis.
(Working meeting, those interested in contributing are welcome.)
–
PASS/FAIL tests
– Review plots from subsystems to evaluate if changes are necessary for
tests at the integrated level.
– Scheduled a meeting on April 30 between I&T (SVAC and Online), SAS and
ISOC to discuss monitoring of parameters during integrated tests and
details of implementation and present SVAC tool to monitor offline
calibrations.
– SAS recon analysis may not be required at this level but we may use SAS
code for digitized data (TBR)
– I&T driven effort
–
Instrument test Analysis
– LAT Collaboration effort. See next slides
–
Infrastructure necessary
– SAS Data pipeline (OPUS) , MC and GlastRealease
– Data analysis code to estimate run time needed during data taking
– Offline Report generation – We were given no requirements so far
– Tool to compare offline results - We were given no requirements so far.

SVAC Instrument Analysis Workshop 1
•
•
•
Date
: June 7 (Monday) and 8 (Tuesday), 2004
Location : SLAC , June 7 (ROB C&D) , June 8 (TBD)
Goal
: Prepare for data analysis during LAT build and testing.
–
Produce MC datasets with two-towers in a grid at different configurations to
– Validate geometry implementation
– Create datasets for data analysis
– Recommend data set sizes based on MC studies
–
Define and assign tasks to participants to
– Evaluate if there are modifications necessary to the reconstruction
– Evaluate if there are modifications necessary to the analysis (merit) ntuple
– Create reference plots for different configurations
–
Define infrastructure necessary for
– Data pipeline (OPUS)
– Report generation
– Comparison of results

Instrument Analysis Workshop 2
•
•
•
Date
: Early July 2004 (TBD, depends on IRR)
Location : SLAC
Goal
: Evaluate MC results and implement changes needed for
data analysis of LAT data obtained during various stages of the
build and testing.
–
–
–
Evaluate results and regenerate MC datasets if necessary
Suggest modifications for data analysis tests with real data and flight
hardware
Work with I&T to evaluate if the data set sizing is
–
–
–
Define what analyses will be done during the build sequence.
–
–
adequate to understand the instrument
and if collection times fit the LAT build and test schedule.
The plan is to have data taking with 1,2,4,6,8,10,12,14,16 towers and
16 towers with ACD.
Define infrastructure needed for full LAT analysis
