Summary of G1 meeting, 12-17-95

This was an impromptu meeting. Minutes are being posted by request of
people who missed it.

Attendence: Smith, Schumaker, Yegneswarin, Burin, Taylor, Miskimen, Barrow

This meeting was an informal discussion of topics related to G1. Presumably
thses topics will be discussed in more detail during the January meeting.

Here are the topics:

1)prescaling tagger

2)trigger

3)start counter

4)beam helicity

5)moeller commisioning

6)target

7)cherenkov

8)commissioning activities

Topic 2), trigger, was discussed the most. A coincidence between the
tagger, start counter and TOF was discussed in detail. The prescaling of the tagger,
topic 1), was also included in this conversion. Beamtime would be useful
to study this trigger.

It appears polarized beam will be delivered to Hall B next spring, therefore
there was a discussion of topic 4). Regardless of the availabilty
and the measurement of the beam polarization, it will take some time and planning
to incorporate the polarization information into the data stream.

As for topic 7), the cherenkov, the plan is to request the CC be filled with
nitrogen gas to reduce its mass. All six sectors are expected to have the
CC installed by the end of january.

It's never to early to start thinking about what the commisioning activities, 8),
should be.

The other topics in this list were discussed briefly. Simon Taylor discussed the status
of the start counter, 3).
