<p>We mounted the following in the chamber:</p>
<ul>
<li>Iris frames - no S2 detectors or mylar</li>
<li>Si pin diode mount with 0.9um mylar - no diode</li>
<li>Target ladder with blank frames - same configuration as elog entry #41</li>
</ul>
<p>At 15:20 we started roughing pumps Ecodry 1 and 2. We opened the manual gate valve followed by the T1600 valve.</p>
<p>After reaching ~10^-2 mBar we started the following turbos:</p>
<ul>
<li>Up 1</li>
<li>Up 2</li>
<li>Down 1</li>
<li>Down 2</li>
<li>T1600</li>
<li>Entrance 3</li>
<li>CSSM</li>
</ul>
<p>By 15:30 the CSSM turbo had reached 56 krpm operating speed and the Up and Down turbos had reached 833 Hz operating speed.</p>
<p>At 19:51 just before we left the lab the pressures read, in mBar:</p>
<ul>
<li>TPU1 = 3.7e-6</li>
<li>TPU2 = 6.9e-7</li>
<li>TPD1 = 1.0e-6</li>
<li>TPD2 = 1.2e-6</li>
<li>CHUP = 6.0e-6</li>
<li>CHDW = 1.4e-5</li>
</ul>
