keyword=N7-40L HV increased
Since rate were lower on this PMT in increased the HV to double the gain but this gave a HV value of -2131 V. since previous HV value of N7-40L on genps1 2002 S11 chan 7 was 1933 V and was increased to 2070 V which is the highest value on the other Glasgow detector.
Previous HV were saved in file NA_dv_044_new_crate7.hv and new HV setting are saved in NA_dv_044_new_crate8.hv
Looking at run 3714 rate looks similar to other bars around 20KHz now.
