Drift Chamber prototypes were constructed to evaluate drift chamber designs for CLAS12
Mini-prototype Performance Measurements
General Operating Condition
Chamber Ionization Gas
Our initial plan will be to use (75/25) flowing though the chamber at a flow rate high enough to exchange the volume once a day.
high Voltage supply
A CAEN 4 channel high voltage supply (N495) will be used to supply HV for the drift chambers. The supply is capable of monitoring currents at the microamp level.
Signal Processing
Cosmic tests
Place chamber between two plastic scintillator paddles to check signals.
scope pulses
DAQ
describe the DAQ for measuring detector output
Electron test facility
IAC 25 MeV electron accelerator
secondary electron beam setup
Description of collimation system goes here as well as lead pencil target. Description of how beam size will be measured or why it isn't needed.
