keyword=Pion Rejector Layer 1 CheckoutUsing the data taken this morning with the central momentum set to 1.0 GeV/c,
I have checked the HV gain matching for the first layer of the pion
rejector. As was seen during Tranversity, most of the energy is deposited
in the first layer. I will have to use 5-pass data to check the second
layer.
The gain matching is still very good. There are a couple channels that
have a higher gain by 6-8% compared to the others. There is also one
channel that is low by about 4%. All the other channels are within 2% of
each other.
Figures 1-4 show the individual pedestal subtracted ADC spectra for the
first layer.
