`Essential List’ Before Production ZPD: None – request production start immediately TSF: (an incomplete list. Only the clearly must do tests) Complete internal connectivity firmware tests. Interface tests for DCH input, neighbor data & TSF output. Full firmware MC event flow test showing no major errors. Interface: TSFi: 1) DCH-DCT calibrations with old and new TSF comparison for ~3000 events to test DCH input path. 2) TSF neighbor data test with 105 bits/line. Apr/11/2003 Su Dong L1 DCT Upgrade FDR: Summary

Essential List’ Before Production (continued) TSFi: 3) TSF->BLT path to 105 bit/line. 4) TSF->ZPD path test to 105 bit/line. 5) Slow monitoring signal manual check. ZPDi: 1) TSF->ZPD path test to 105 bit/line. 2) ZPD->GLT path test to 105 bit/line. GLTi: 1) ZPD->GLT playback for all 8 ZPD channels. 2) Cosmic run at IR2 with no detectable errors.

L1 DCT Upgrade FDR: Summary Schedule Production milestones: ZPD: Production start Immediately after FDR. TSF: a) Late Apr/Early May: load 6 TSF prototypes. Critical for June commissioning. b) Late June: start pre-series (hopefully is production). Critical for Sep/5 Run-4 startup. TSFi: Start production end of Apr/Early May. ZPDi: Start production early May. GLTi: Start production late May. Aim for all boards delivered for Sep/5 Run-4 startup by end of August. Apr/11/2003 Su Dong L1 DCT Upgrade FDR: Summary

Key elements for June Commissioning TSF/TSFi interface tests to qualify TSFi for production and TSF prototype for 6 board loading. TSF firmware completion. Online/DAQ/Offline software necessary to run new DCT in BaBar datataking. Apr/11/2003 Su Dong L1 DCT Upgrade FDR: Summary
