<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>

Things to check:

<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>

Once setup us completed:

<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>

If everything working:

<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>

Travel times

Nick: 8-16, Annie 8-12, Tom, 7 -?, Claudia, 8-10, Emmanuel asap until end of run

Measurement runs until Octover 2nd. Disassembly by Nick and Emmanuel.

additional trips during the measurement as required (if something breaks/fails etc. )

TO Do: MCA availability at nTOF for quick noise checks (Nick)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; how many&nbsp; channels in 14 bit, how many 12 bit (Nick)

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; depletion voltages &nbsp; for detectors (Tom)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Register the eqipment at CERN as Edinburgh property (Claudia)
