1         PURPOSE

The purpose of this document is to collect all the data for the Glast LAT Tracker (TKR) Tower End Item Data Package (EIDP), in compliance with LAT-TD-04350 and PRC_Pi_QC_005. This document is compiled and reviewed within the Tracker subsystem prior to shipment of the tower from INFN to SLAC. The contents of this document have been coordinated between LAT Integration, Test, and Calibration (IT&C), LAT Systems Engineering (SE), LAT Quality Assurance (QA), and the TKR subsystem.

Note: tracker tower 16 is a non-flight module as many non-flight parts were used for its integration (see NCR/FM/INFN/PI-593) and environmental tests were not performed. This document serves for traceability purposes
