NEW New Target HV LV setup and monitor with old DCS - PADME-Experiment/padme-fw GitHub Wiki

To monitor the NEW setup of the Target HV ,LV and currents you can check it at http://l0padme3:9090/dcs the standard General/DCS_summary page (status continuously displayed each 180 secs).

Now the target LV voltages are managed through the last CAEN crate new board (board 15:LV). There is NO NEED to connect directly to the CAEN HV supply !
Since 6/10 the target HV is managed via a TTI NEGATIVE power supply. The on/off procedure for HV should be made ONLY with the following procedure.

To set ON/OFF the target you have to log onto dcs@l0padme1, and type the following (self-explanatory) commands :

onvolt_target_hv_tti --> sets ON at the standard HV set on the TTI power supply for the target

The standard Current for 245 V operational voltage should be ~ 10/20 uA (should be < 3.5 uA, but we do not have the sensitivity via TTI)

offvolt_target_hv_tti --> sets OFF the target HV

onvolt_target_lv --> sets ON at the standard LV set on the CAEN channel (slot 15/channel 1) for the target

The standard Current for 5 V operational voltage should be ~ 0.14/0.15 A

offvolt_target_lv --> sets OFF the target LV

You can read the actual target voltage situation in the summary page of the old DCS. The data for the target LV voltage and current are logged and displayed on the Padme DB via the new DCS. THE HV is NOT (at the moment) in control of new DCS and NOT logged onto Padme DB
