keyword=Current CalibrationsWe have started a current calibration runs with the Faraday Cup.
Linearity Runs: E-arm: 20616
H-arm: 3316
We cycle through at intervals of 90 seconds with the following currents: 34.0, 20.44 (trip), 20.40,10.70, 5.25 (2 trips), 5.25, 2.02, 2.02, (trip), 2.02, 1.045, 1.045, 0.51, 0.50, .170 micro A.
Standard Calibration with Faraday Cup
Standard Runs: E-arm: 20617
H-arm: 3317
We did only 3 steps with max. beam current of 34.0 microA. (see fig. below). There was a BLM trip and we could do no more for now.
