<ul>
<li>All detectors powered off</li>
<li>Closed line and quadrupole valves</li>

<li>Closed manual gate valve and T1600 Backing valve</li>
<li>Stopped Ecodry 1 and 2 roughing pumps</li>
<li>Switched off CAMAC and RAL electronic crates</li>
<li>FC - 0 suppression voltage switched off (was set to -360V for beam measurements)</li>
<li>Switched off both NIM crates</li>
</ul>
<p>After venting the chamber I dismounted both S2 detectors and the 12um mylar in front of each detector</p>
<p>I also dismounted the diode from the chamber, but left the 0.9um mylar glued onto the 4mm diameter metal collimator</p>
<p>I left the target ladder in the chamber</p>
<p>I remounted the central and downstream lids onto the chamber, the diode mount with mylar was left mounted on the central lid</p>
<p>We performed a general cleanup around the lab of the tools used during this shift</p>
<p>At 19:30 we left the lab ^_^</p> |
