MINUTES FROM THE COOLER-CSB GROUP MEETING

December 3, 2001 - EJS

Present: Chris Allgower, Andy Bacher, Chris Lavelle, Hermann Nann, John Olmsted, Tom Rinckel, and Ed Stephenson

Small Items:

• We still need to make a metal collimator to go in front of the position sensitive silicon detector (luminosity monitor).
• Chris Allgower will attempt to get the timing readout going during the Cooler access time next Monday and Tuesday.
• Now that the six-degree magnet is on, we need to check whether this had changes any of the Pb-glass PMT gains.
• There are two bottles of D2 gas coming for CIPIOS. When they arrive, we will get back the bottle for the T-region.

TOPICS FOR THE PROGRAM ADVISORY COMMITTEE

The charge to the speakers contains three items:

1. State whether the physics motivation for the experiment has changed and, if so, how.
2. Review the readiness of the experiment and state who would participate.
3. Review the resources needed, including beam, integrated luminosity, detectors, energy, shifts, etc.

The physics motivation has not changed, and the expected running time goals are as they were at the PAC meeting in June, 2000. What has improved is the level of interest displayed by the theoretical community in coming to grips with the calculation of the cross section.

We should be prepared to say what we would do if the Cooler comes up in January with either a proton or deuteron beam. In the proton case, the priority will be to commission the Pb-glass detectors using the p+d -> 3He+pi0 reaction. For the deuteron beam, the priorities are (probably in order):

1. Develop the intensity of the deuteron beam in the Cooler. We need something close to 2 mA circulating current. See whether this can be done with both the unpolarized and the polarized beam.
2. Calibrate the luminosity system using HD gas.
3. Debug the channel and check rates.
4. Measure d+d cross section and analyzing powers to check the calculation of the distortions.

Personnel to be on shift remains an issue. At the moment, the backbone of the effort will be Allgower, Olmsted, and Stephenson. It is clear we do not have the people locally to maintain two people per shift.

There has been a management plan and, within the constraints of Cooler access, we have met the milestones to this point.

There are no known issues that would prevent us from reaching the experiments goals.

We will review this next week.
