LJ 39 BNC Connector

Esaminando il connettore ma dal punto di vista meccanico sembra tutto a posto. Si ripassano le saldature ugualmente, nel caso qualcuna fosse fredda. Risultato: il rumore non c'e' piu'!

In compenso il rumore generale del 39 e' risalito ai livelli soliti. Visivamente ci sono grossi rombi in giro. I

Oggi i rombi non vanno via. Anche spengendo tutto e lasciando acceso solo il ccd39, i rombi rimangono su tutti e quattro i quadranti.

Il rumore rimane anche quando solo il ccd39, tenendo spento pure il "main power". Quest'ultimo pare che spenga anche il 24V, e in effetti, quando si accendono main power e FW, ADC e rerot, si nota del rumore in piu' che si sovrappone ai rombi.

Mauro risistema la calza di uno dei BNC che arrivano alla testa del ccd, che non chiudeva bene sul cavo e rischiava di staccarsi.

AGW remounted

- Valvola cooling perde

- 110V fatto col trasformatore portatile invece del circuito torre -->> Il rumore magicamente sparisce!!
