Mini-prototype
Drift Chamber prototypes were constructed to evaluate drift chamber designs for CLAS12
Mini-prototype Performance Measurements
General Operating Condition
Our initial plan will be to use (75/25) flowing though the chamber at a rate to exchange the volume once a day. 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.
