The anode PS is turned off and connected to HV common.
the Target is connected to a -18V PS at the center support (Feed through A) for a on/off test of ion suppression
NOTE: there is a shortcut target <--> HV gnd, most propably due to the thermocouple touching something after pumping. |

The powersupplies added to the teststand for operation of the IGLIS source have been removed from the HV cage as well as the RFQ driver.. The connections
of the 9PIN connector in the HV cage have been grounded and the wire used for an voltage offset of the source has been removed.
