 The bias for the object scintillator is controlled via the H.V. power supply {{:​wiki:​Manual_Canberra_HV_3002D.pdf|Canberra model 3002 D}} located in the crate to the right of the data-U6 (see figure below). The voltage will be adjusted at the beginning of the experiment. This scintillator has to be turned off or put on "​standby"​ when entering the vault due to its sensitivity to light. The voltage used for this detector depends on the fragment nuclei that will be measured. Check with **Daniel Bazin** for a reference value. The bias for the object scintillator is controlled via the H.V. power supply {{:​wiki:​Manual_Canberra_HV_3002D.pdf|Canberra model 3002 D}} located in the crate to the right of the data-U6 (see figure below).
