  1. Gamma-ray Large Area Space Telescope GLAST LAT System Engineering ACD Early Integration Test Plan Rich Baun SLAC rbaun@slac.stanford.edu (650) 926-3520

  2. ACD Early Integration Test - Overview • Test Description • With 8 Towers in the grid and the ACD installed execute functional, performance, and internal interface testing of the ACD, Trigger, Dataflow, and Tracker subsystems. • Perform the LAT CPT, augmented to include the ACD, and SVAC testing while the entire configuration is powered. • Entrance criteria • Complete the planned 8 Tower testing of the CAL and TRK prior to installation of the ACD • Successfully completion of the ACD Pre-Installation Test

  3. ACD Early Integration Test - Purpose • Reduce the risk of the ACD Integration to the LAT. • Specifically, perform the following activities with 8 Towers and the ACD integrated: • Verify and characterize the function and performance of the Trigger subsystem with respect to the ACD • Verify and characterize the function and performance of the Dataflow subsystem with respect to the ACD • Verify the ACD performance while integrated to the LAT • Verify CAL and TKR performance is not adversely effected by the ACD installation • Verify the performance of the LAT as a whole • Validate, to the maximum extent possible, the LAT Level ACD, Dataflow, and Trigger test scripts and test schemas.

  4. ACD Early Integration Test - Configuration • GSE Configuration • Current configuration, with the following exceptions • Latest version of LATTE 4.9.x installed • Upgraded BPU installed • LAT Configuration • Eight Towers in the Grid • EM GASU and PDU installed • GASU flight cables installed • ACD and ACD flight cables installed • EMI shield, ground panel, and Bulkhead bracket installed • Required to mechanically support ACD/GASU flight cables
