<ul>
<li>Start 9th August, access to EAR-2 11 am earliest but can start in rack area before</li>
<li>Setup to be used: 1 dE (16 strips, 20 um thickness) + 1 E (16x16 strips, 150 um thickness. We have a spare for each thickness</li>
<li>Sample and detectors to be mounted on the same flange</li>
</ul>
<p>Things to check:</p>
<ul>
<li>alignment with beam centre (lasers and/or gafchromics foils)</li>
<li>is the setup stable to knockes, can all detector / sample positions be well reproduced when making changes</li>
</ul>
<p>Once setup us completed:</p>
<ul>
<li>checks with pulser</li>
<li>mounf LiF sample number 3 and run with neutron beam</li>
<li>check that all strips have signals</li>
<li>confirm shape of gamma flash and that short times can be anaysed in both detectors (~1.8 us after flash)</li>
</ul>
<p>If everything working:</p>
<ul>
<li>measure LiF-3 and the switch to Al-26</li>
<li>towards end of the run we can also measure B-3 and the empty brass frame (Frame without mylar)</li>
<li>proton statistics: 1E17 LiF-3, 1F17 B-3, ~3E17 Empty, 5.5 E18 Al-26</li>
</ul>
<p>Travel times</p>
<p>Nick: 8-16, Annie 8-12, Tom, 7 -?, Claudia, 8-10, Emmanuel asap until end of run</p>
<p>Measurement runs until Octover 2nd. Disassembly by Nick and Emmanuel.</p>
<p>additional trips during the measurement as required (if something breaks/fails etc. )</p>
<p> </p>
<p>Attached: photos of previous setup</p>
<p> </p>
<p>TO Do: MCA availability at nTOF for quick noise checks (Nick)</p>
<p> how many channels in 14 bit, how many 12 bit (Nick)</p>
<p> depletion voltages for detectors (Tom)</p>
<p> Register the eqipment at CERN as Edinburgh property (Claudia)</p>
