<p><b>New page</b></p><div>MAGNET FOLLOW-UP<br />
<br />
* Design drawings<br />
::* aim is to check geometrical fit and mechanical aspects<br />
::* ongoing discussions about availability of labor and timeframe (CH, BW)<br />
::* frame drawings can be done after magnet drawings<br />
<br />
* Background simulations<br />
::* Issue at hand: show that background is less with the current configuration compared to the configuration with the horizontal bend. Difficult to do figure out up/down dependence, i.e., do blocks at small angles see more/less radiation.<br />
::* In principle can use GEANT 4 for these simulations. The code GN and BW used for the photon source simulations may serve as a starting point. Contact Gabi to get the GEANT 4 code (RE)<br />
::* Post technical note on compact photon source - contains information on GEANT 3 and GEANT 4 comparison (TH)<br />
<br />
<br />
READOUT<br />
<br />
* Calorimeter prototype has been moved to test lab and new crate and DAQ setup for tests<br />
<br />
<br />
PWO CRYSTALS<br />
<br />
* Received back the five crystals from Giessen. Results of these tests have been posted on the Wiki. Results from tests carried out at Caltech and BNL have also been posted. <br />
<br />
* Received two crystal samples from Crytur at CUA - currently being tested<br />
<br />
* Outline for quality assurance procedure and crystal specifications in preparation <br />
<br />
<br />
COLLABORATION MEETING<br />
<br />
* Planned adjacent to Hall A/Hall C meeting. Dates to be determined (CH)<br />
<br />
<br />
EIC R&D <br />
<br />
* Aim is to procure a few full-sized crystals from Crytur for testing</div>Hornt
