New vlaues for DRALS |
|
|
The Timing for DRALS has changed to a 12 min measurement window (max time for laser scan). The duration of the laser ramp planned to be 10 min. So we have 2 mins to openfile / closefile etc.
DRALS settings
Measurement Window (Voltage Ramp): 720 001 ms (12 mins + 1000us)
Cooling Window: 16800 us
MEAS0/MEAS1: 16800us
Phase delay (Time for the change of the voltage): 3000us
Voltage Cool: -900V
Voltage Meas0: 3243V (min peak)
Voltage Meas1: 3243V (min peak)
Subtriggers
1: 5500
2: 2000
3: 2200
4: 2400
5: 200 (not wired, but number is needed internally)
6: 200 (not wired, but number is needed internally)
7: 200 (not wired, but number is needed internally)
The voltage on the maximum of the main DR-Peak would be 3348V.
The trigger pattern for the DAQ is running all the time (also during injection) if DRALS mode is ACTIVE (toggle with 511)
In order to avoid the start of the voltages, please use GENESYS (IO3) to set the starting trigger pulse inactive.
DRIFTTUBE Cooling requires cooler settings in ParaModi / ESR Manipulation / deltaUacc in SC 10 = 880 V (SC 8 will be changed automatically).
without drifttube ramping (no trigger) the value is -20 V
An NTCAP file was opened before the tests and during the scraping: 2025-05-16_18-43-02. |
