The DR measurement was repeated with proper electron cooler settings. Readout of electron cooler HV is not affected by the Grafana failure and can be displayed in Medusa in the View "Log-Display". Measured voltages in Subchain 8 are:
- 500mA cooler current, file 25-26 (CR DAQ), NTCAP folder closed
Ohmlabs | 205854 |
PTB 3.2 | 205861 |
PTB 3.3 | 205862
|
- 250mA cooler current, file no.27 (CR DAQ), NTCAP folder "IQ_2025-05-13_00-18-48"
Ohmlabs | 205812 |
PTB 3.2 | 205819 |
PTB 3.3 | 205819

The cooling energy is 900V lower, since it is compensated by the drift tube HV. |
