Other notes/issues
1-Van De Graf test, how and where does it fit
2-The science cal plan calls for EM tests, not covered under this flow
3-How does Steve Ritz data flow verification fit into this plan?
4-Where are algorithms for EGSE software (and SAS software) specified? They
need to be consistent

Strategy for Completion
• Phased approach to provide planning necessary for first 6
months of integration
• Focus is on Calorimeter and Tracker first, followed by DAQ
boxes, then ACD

LAT Assembly Sequence
• LAT Assembly Sequence LAT-MD-00676
– Contents
• Defines in detail the sequence of operations necessary
to integrate the LAT
• Focuses on mechanical operations, and calls out
electrical tests to be run from separate procedures
– Status
• Draft completed, some refinement needed
– Schedule
• Personnel reprioritized, ETC TBD
• Mitigation
– Sufficient detail available to proceed, remaining work is
primarily clean up

LAT Performance and Operations Test Plan
•
LAT Performance and Operations Test Plan LAT-MD-02730
– Contents
• Defines at a high level each of the individual tests (e.g. TE103,
Tracker Bias Current)
• Define when the test will be run (Functional Test,
Comprehensive Test, Integration test …)
– Status
• Draft initiated (samples on next viewgraphs)
• Details worked in weekly meetings with I&T and subsystems
• Will include definition of 2 tower test derived from End-to-End
Committee results
– Schedule
• First cut out by end of month as part of an incremental release
series
• Mitigation
– Information generated by a team effort (including members of
End-to-End Committee), so test development can proceed in
parallel

Test Definition Sample
• Tracker GTRC configuration register and readback
– The GTRC chips are sequentially addressed and their
configuration registers loaded with a bit pattern. Each time
the register is read back and checked for errors. The test is
repeated with the complement of the bit pattern. The test
then is repeated with a broadcast address for writing the
register, followed by sequential readback. (Based on
Tracker Test TE201)
• FSW Tracker Configuration Test
– This test shall verify the ability of the SIU to configure the
TKR subsystem as desired and read back the necessary
configuration information to completely determine the TKR
subsystem configuration (Based on FSW test 7b)

Integration Drawings
• Integration Drawings
– Contents
• Defines how the pieces delivered to I&T relate and
provides some assembly information
• In some cases, provide a model with internal details
removed to facilitate model usage (outline drawings)
– Status
• Drawing tree defined
• Model and drawing completion on hold
– Schedule
• Will take approximately 2 months after effort is restarted
to complete model integration and drawings
• Mitigation
– Many of the models can be used now to get views
necessary for integration procedures
