<p>On 23/02/2018:</p> <p>At the end of the February 2018 shifts the detectors bias settings were:</p> <p>S2 bias = -130.3V, leak I = 2.42uA</p> <p>Pin diode bias = -70.1V, leak I = 0.00uA.</p> <p>Both detectors were switched off, the preamp power was also switched off.</p> <p>At 18:22 the chamber pressures read:</p> <p>TPU1 = 2.3e-6 mBar</p> <p>TPU2 = 6.9e-7 mBar</p> <p>TPD1 = 1.6e-6 mBar</p> <p>TPD2 = 1.7e-6 mBar</p> <p>CHUP = 5.7e-6 mBar</p> <p>CHDW = 1.5e-5 mBar</p> <p> </p> <p>We closed the manual gate valve and T1600 Backing Valves. We switched off the turbos and roughing pumps Ecodry 1 and 2.</p> <p>The nim bin for the quad bias and other nim modules was switched off. The Lecroy 1434A CAMAC Crate was switched off. The RAL shaping amp crate was switched off.</p> <p>We put away the S2 and pin diode detectors.</p> <p>The alpha source was removed from the target ladder.</p> <p>The target ladder was remounted in the following configuration:</p> <table border="1" cellpadding="1" cellspacing="1" style="width:500px"> <tbody> <tr> <td>Position</td> <td>Target</td> </tr> <tr> <td>1</td> <td>Blank 3mm</td> </tr> <tr> <td>2</td> <td> <p>No Target</p> </td> </tr> <tr> <td>3</td> <td>CH2 VII</td> </tr> <tr> <td>4</td> <td>CH2 III</td> </tr> <tr> <td>5</td> <td>CH2 IV</td> </tr> <tr> <td>6</td> <td>No Target</td> </tr> <tr> <td>7</td> <td>No Target</td> </tr> </tbody> </table> <p>We performed a general tidy-up around the chamber and workspaces we used during the past 9 days.</p> <p>I took the PB-5 Pulse Generator and three 64 Way - 2X32 Way ribbon cables (for minor modification) back to Edinburgh.</p> <p>I also took the mylar we discovered in the beamline on Tuesday 20th as a keepsake/ reminder anything can happen</p> <p>At ~20:00 we declared victory for the week.</p>
