keyword=HMS Drift ChambersCurrent status of HMS Drift chambers. All cables have been checked. The ringing
is gone. There are several dead wires. This could be due to bad discriminator cards.
At this time we don't propose to swap anything out as this s as good as the chambers
have looked in their life.
DC2 wire U30 is probably bad because of a poorly plugged in cable (from wires to
Disc. card) but the shield should be taken off and the chamber switched off before
trying to adjust it.
On DC1 y43 and y'40 wuld be nice to fix if possible but they do not
overlap in space (contrary to their numbering)
