  1. SENSOR MEASUREMENTS • Probe Station: IV, CV, IIV, etc. • Want to: make measurements as function of different vacuum levels, temperatures and bias voltages. • Need a new setup… (from Radia&Nabil’s talk) R. Mountain, Syracuse University VACUUM Scrapbook 2006 -1-

  2. HV/HV SYSTEM DESIGN BB#1 A,V CIRCUIT KEY VACUUM ELECTRONIC COOLING GAS OPTICAL • PURPOSE Sensor characterization at different vacuum levels, temps, and bias voltages • DESIGN PARAMETERS Pressure: 10-1 ~ 10-4 mbar Temp ~ -7 deg.C Est.
