<p>Valery,</p>
<p>During the testing I am assuming during pulse testing LV will be
on and HV will not be used? As far as the laser testing, where
will this happen and can you describe the test set up and give the
specification of the laser. I'm trying to identify the hazards.<br>
</p>
<p>Thanks</p>

<div>All front-end boards will be extensively tested prior to
the installation into the detector.</div>
<div>There are 3 front-end boards:</div>
<div>1. FPGA board</div>
<div>2. ASIC board</div>
<div>3. Adapter board</div>
<div>All of them will be tested first with the generator input
pulse. We will send and detect the signal from each out of 25K
channels.</div>
<div>At the end we will take the calibration data using our
laser test. During this test we will attach MAPMTs</div>
<div>to the front-end.</div>
<div><br data-mce-bogus="1">
</div>
<div>At the same time we will install the tested boards to the
electronics panel. I hope the electronics panel will be
completely equipped in May. We plan to take cosmic data after
that. For this test the electronics panel will be rotated to
the horizontal position.</div>
<div><br data-mce-bogus="1">
</div>
<div>The HV and LV will be provided to the electronics and PMTs
using the standard RICH CAEN HV and LV crate.</div>
<div>MAPMTs and front-end will be located in the completely
isolated volume. So I don't see any problems with safety.</div>
<div>We plan to test cooling system after the competition the
assembly of the electronics board.</div>

<br>
I need your procedure for testing the electronics. Can you
tell me what <br>
testing you want to do to the electronics boards prior to
installing <br>
them in the detector. Additionally, how do you plan to
provide power to <br>
the boards, will any cooling be necessary?<br>
<br>
Thanks,<br>
<br>
