keyword=Will adjust PMT HVThe trigger requires 4 PMTs. Below is paddle 3 on
Right spectrometer which has low efficiency (see halog 48895)
and also shown is paddle 4 which has higher efficiency.
Paddle 3R on plane 2 needs higher voltage, though it
is not obvious this is the cause of inefficiency (I think
threshold is around 500 - 600).
