UPDATE NSF<br />
<br />
<br />
MECHANICAL DESIGN<br />
<br />
* Two crystal layout options<br />
<br />
::* regular<br />
<br />
::* rows shifted to minimize empty space<br />
::* with the current beam flange this gives 0.15 higher eta (corresponding to ~half a block) on one of the sides; on the other sides there does not seem to be much gain<br />
::* no significant extra mechanical material needed<br />
<br />
* Discussion about different treatment of these rows of blocks in terms of clustering reconstruction<br />
::* more difficult<br />
::* balance gain in acceptance with difficulty<br />
::* general consensus is that it should be possible to have a clustering reconstruction algorithm that can take care of the irregular shape, but needs to be checked<br />
<br />
* Discussion about different size blocks in that region<br />
::* instrumenting irregular block sizes with SiPMS+boards would be more challenging<br />
::* integrating different block sizes might be challenging<br />
<br />
* In general, people are in favor of increasing acceptance, but concerns about clustering with irregular shape - try to study with clustering algorithm<br />
::* Renee will talk to Dmitry<br />
::* Justin will talk to Sasha<br />
<br />
<br />
'''READOUT - SIPM'''<br />
<br />
* SiPMs with 6mm x 6mm were sent to <br />
<br />
* Larry got boards made and assembled with SiPMs<br />
<br />
* Considering to send some of them to Germany for radiation testing<br />
<br />
<br />
'''SLOW CONTROLS'''<br />
<br />
* Items that may need more discussion<br />
::* gas system: how to design such a system in a more open geometry compared to NPS<br />
::* LED system<br />
::* power supplies for 3000 channels<br />
<br />
* Comment on interaction between calibration and slow</div>Hornthttps://wiki.jlab.org/cuawiki/index.php?title=General_EEEMCal_Meeting_Agenda_3/22/24&diff=6170&oldid=0General EEEMCal Meeting Agenda 3/22/242024-03-26T20:29:42Z<p>Created page with "DISCUSSION ITEMS * Proposal update * Mechanical Design * Readout - SiPM * Slow Controls * Other"</p>
