(Proper) Cooler settings |
|
|
We change the acceleration voltage of the electron cooler and observe the platform high voltage and the count rate at the particle detector south.
Cooler current at 100mA.

5kHz Shottky width at proper cooling conditions.
Modified bunching HF in beam process 7 and 10 in Paramodi folder "Ring HF" to get coasting beam conditions.
Afterwards manipilated the electron current from 100mA to 200mA to 50mA in BP8. |
