Collect 10M triggers with all CDC HV set to the following voltage:

2125 - You can omit this one setting if less than 1h has passed since the end of the preceding run, as 2125 V is the nominal setting 2150 2100 2075

If the first 4 runs took less than 4h total, then continue with 2050 2000 1900 until finished or 4h is up. If the first 4 runs took more than 4h and the weather conditions are not stable, the scan might have to be repeated when the beam (or the atmospheric pressure) is more stable.

Contact CDC experts (Naomi or Beni) in case of problems or questions.
