CUSTOM MADE
• DUE TO MANUAL WORKING NEEDED FOR ASSEMBLY
AND POTTING WE EXPLORE A COMPLETELY CUSTOM
SOCKET
DURING VERY PRELIMINARY TESTS WE BUILT SOME HOME MADE PMT SOCKETS
AND NO DIFFERENCE WAS FOUND IN PERFORMANCES VERSUS HAMAMATSU
SOCKET (WE COULD FURTHER INVESTIGATE ON THIS ITEM)
WITH A CUSTOM PMT SOCKET WE CAN
REDUCE POWER SUPPLY CURRENT
REQUIREMENTS AND DISSIPATE LESS
POWER ON VOLTAGE DIVIDER AND PMT
FLANGE
