Agenda
- Production Construction Tracking (Dave)
- First package tests (Vlad)
- Cathode corrosion
- Recent SEM results Viton+Apiezon not cleaned, Viton+Apiezon cleaned with alcohol, Viton+Apiezon cleaned with xylene
- Engineering (Bill)
- Electronics (Chris, Nick)
- Third package tests FDC E-log (Beni)
- TDR, pages 132-143 (Lubomir)
- Other: plots for Eugene's talk
- packages: #1,#3, #4
- corrosion: [1], EPDM optical, EPDM spectrum, Viton+Apiezon spectrum
- oxygen issue: g10 coating, and Viton+Apiezon reduce O2 from ~10,000ppm to <100ppm.
- test results: Wire Resolution from the full-scale prototype 40/60% Ar/CO%, 5*10^4 gas gain
