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 Tower 1 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.

(*) Tower1 is delivered with a tray configuration as documented in this EIDP. A previous configuration with a different tray located in position 17 was first assembled and environmentally tested, showing a malfunction on tray17 (see NCR/FM/INFN/PI-430). RUN1 refers to this 1st configuration. To cure the malfunction, this tray was replaced with another flight unit, while all other components of the tower remained unchanged; this 2nd configuration was then environmentally retested. RUN2 refers to this 2nd and final delivery configuration
