GLAST LAT Tower 16 Pre-Ship Review and Assembly Highlights

This report details the assembly and testing of the GLAST LAT Tower 16, conducted from October 25-28, 2005, at INFN Pisa. It includes the assembly of the complete tray stack with 15 non-flight trays, the installation of a full cable set, and alignment of sidewalls. Notable components include the replacement of tray 17 and the presence of minor mechanical issues in some trays sourced from flight towers. Performance metrics indicate an average tower efficiency of 99.5%. The findings will aid in calibration studies as Tower 16 serves as a spare module.

  3. Tower 16 – configuration details Tower PN: LAT-DS-00722 (rev3) Tower SN: 16 18 non-flight trays: • 5 from tower0 – some needed rework • 4 from flight towers 1,14,7,8 and showing anomalies at high T and/or vacuum – removed and reworked where necessary • 1 with anomalous GTFE • 5 with minor mechanical problems 3 non-flight cables: • C0-023, C6-008, C7-009 4 non-flight sidewalls: • EM laminate • 50 mm Al on ext. surface • pocket for extra-thick closeout out of specs Tracked in NCR INFN/PI 593

  4. Tower 16 – functional test details issues to deal with when testing layers with more than 16 bad chans or rare anomalies 3 9 Tracked in NCR INFN/PI 594 Overall bad channels

  5. Tower 16 – efficiency performance Average tower efficiency is 99.5% (waiting enough for FE2 on Y11 to warm-up and taking into account also Y15 with ~160 bad chans)
