Drift Chamber prototypes were constructed to evaluate drift chamber designs for CLAS12 MiniPrototypeWirePattern.jpg

Mini-prototype Performance Measurements

General Operating Condition

Our initial plan will be to use [math]ArCO_2[/math] (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.
