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 (N470) will be used to supply HV for the drift chambers. The supply is capable of monitoring currents at the microAmp( A) level and voltages at the Volt (V) level.
Signal Processing
The output signals from the drift chamber will be processed through several NIM based modules.
