MAPMT Base Board

Front view of the MAPMT high voltage baseboard. The  MAPMTs plug into the custom designed sockets shown (16 in total). Two MAPMTs are shown. The spacing between tubes is to allow for a mu-metal magnetic shield.

Back view of MAPMT HV base board: One can see the large number of surface mount components which comprise the individual 12-stage voltage divider chains. Also visible are the 8 readout 34-pin fine pitch connectors (serving 2 MAPMTs). The machined holes in the center of each field are to clearances for the vacuum post extending from the back of the MAPMT.
