<p>Hi Valery,</p>
<p>As I understand it pulse generator and laser testing will not be
done in the clean room. Could you write a procedure for the test
which will be done in the clean room. It doesn't have to be
anything other than...</p>
<p>1. Turn on HV <br>
</p>
<p>2. Turn on LV</p>
<p>.....</p>
<p>N. Turn off in reverse order.</p>
<p>That way we can evaluate the hazards. I will add this to the
overall installation and testing procedure.</p>
<p>Thanks,</p>
<p>Marc<br>
</p>

<div>The front-end electronics test with generator will be done
in the F-wing. We will not use HV for this kind of the test.</div>
<div>The assembled with MAPMTs test will be done in the High Bay
area where our laser stand is located.</div>
<div>We have all safety documents for this test. We need TOSP

<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>Hi Marc,</div>
<div><br>
</div>
<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>
</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>
</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>
<div><br>
</div>
<div>Hope it helps,</div>
<div>Regards,</div>

Valery,<br>
<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>
