<p class="x_x_x_MsoNormal">Congratulations to everyone in the group for the great success on the first PPU cryomodule qualification. Thankyou for all your hard work to accomplish this goal, we have an amazing team. Testing of all four cavities was completed
and all reached our 18MV/m admin limit and exceeds the PPU specifications for installation in the accelerator. We should all celebrate with a beer at Crafters Brew this Friday first round is on me.
</p>
<p class="x_x_x_MsoNormal"> </p>
<p class="x_x_x_MsoNormal">Plans for the PPU01 vacuum are as follows:</p>
<p class="x_x_x_MsoNormal"> </p>
<p class="x_x_x_MsoNormal">The ion pump will be turned off today (pump cart is already isolated, right angle valve) and the start of warmup should begin. When the temperature of the cavities all reach 20K then the pump cart should be opened to the beamline
(open the right angle valve at the ion pump) . When the overall pressure on the beamline reaches its baseline or low pressure 3e-8Torr, then the pump cart should be isolated and the ion pump turned back on.</p>
<p class="x_x_x_MsoNormal"> </p>
<p class="x_x_x_MsoNormal"> </p>
<p class="x_x_x_MsoNormal">Thanks in Advance</p>
