Weekly Meeting Minutes - May 23, 2003

Attending: Ashot, Mark I., Chewie, Brian, Marianna, Dave K., Itaru, Raphael, Eric, Marvin, Dan, Aram, Dave L., Steven, Liping, Justin, Yar, Dustin, Abdellah, Anatolly, Joshua, Mabub, Galen
On Phone: Dan

Announcements:
Students should put their time 50/50 into calorimeter construction and learning (lectures, etc).

Installation is January 3rd and 10 days of beam time in February, then G8 gets 2 months before we return.

Prepare to give a 3-5 minute status report every week, but try and solve problems beforehand as discussion time will be limited.

Engineering:
Dave: Reminder of safety issues - see him, Ashot or any supervisor if you have questions.
Delay cable bundle construction continues: Tom Carstens needs 2-3 students Monday at 8 am. Brian & Chewie are first up, weather permitting.
Deck being rebid with vendors visiting next week.
HyCal frame modifications done next week. Before they’re finialized, Ashot & Anatoli need to look at it this weekend. After that it’ll be too late for changes.
Trigger electronics rack design complete, ETA mid-July.
HyCal insulation design complete & foam is here, waiting on the welding.
Lifter rails repositioned, ETA on welding 2 weeks. Motion control specs requested from Mark Ito.

Hardware:
Lead-glass Detectors: 450 modules done & all PMTs checked. HVD needs cabling & mu-metal needs cutting.
Lead Crystal Detectors: all 1200 modules soldered & 300 high-rate checked. Optical test done on 500 and geometrical tolerance tested on 300.
Discussion of wrapping results.
PC board construction needs manpower.

Yar: Temperature monitor for HyCal-0 complete with two different display formats. Discussion of display: upshot is show a few select sensors and monitor the others.

Eric: All veto counter parts are on-site and only need wrapping. Presentation of design. Discussion of vertical resolution shelved for later meeting.

Liping: Presentation of existing beam profile detector hardware - it’s ready for installation. Software is in progress. Discussion of placement & resolution.

Marianna: Presentation of optical test results. Discussion of truncating testing as everything is turning out so well - no resolution. Measurement process needs manpower as Marianna’s leaving Sunday.

Software:
Dave: Presentation of analysis methods.

Itaru: Presentation of photon flux analysis. Discussion of gates & timing.

Dustin: Presentation of photon flux analysis via Compton scattering.

Raphael: Presentation of analysis of the 2001 data. Discussion of entire software package.

Aram: Presentation of pair spectrometer tagging ratio analysis.
