R.Ciaranfi 25/05/ NA62 CUSTOM PMT SOCKET FOR R7400 TUBE R. Ciaranfi

25/05/ OUTLINE HAMAMATSU BASELINE HALOGEN FREE CABLE SOCKET PATCH CUSTOM MADE SOLUTION –PREVIOUS PROTO –DIFFERENCE PROTO VS HAMAMATSU –CURRENT BEST FIT COST AND TIME

R.Ciaranfi 25/05/ HALOGEN FREE CABLE LOW SMOKE HALOGEN FREE

R.Ciaranfi 25/05/ HAMAMATSU BASELINE 600 AVAILABLE PMT SOCKETS NEED MODIFICATION (JUNCTION) NEW 1400 SOCKETS WITH 2 M OF RG174 = 77 € (108K€) –NO HALOGEN FREE CABLE –WITH ALOGEN FREE WE SUPPOSE AN EXTRA COST WE NEED A SOLUTION TO USE HALOGEN FREE CABLES

R.Ciaranfi 25/05/ SOCKET PATCH INTERMEDIATE SOLUTION TO USE HALOGEN FREE CABLE RG174 HALOGEN FREE RESIN POTTING HV WIRING HALOGEN FREE Dscn6482.JPG PIN HV DIVIDER INCLUDED 66€ SOCKET ONLY

R.Ciaranfi 25/05/ 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) Old_infn_proto_00-pdf WITH A CUSTOM PMT SOCKET WE CAN REDUCE POWER SUPPLY CURRENT REQUIREMENTS AND DISSIPATE LESS POWER ON VOLTAGE DIVIDER AND PMT FLANGE
