<p>Increased conditioning temperature in D2000 #3 and 4 (behind detectors) to 150C from 130/140C. No appreciable change in temperature. Minor effects in pressure.</p> <p>Pressure has completely recovered from yesterday and did not settle on higher/lower plateau value which may suggest conditioning the D2000 NEG elements has helped outgassing the chamber as a result of the low baking temperature.</p> <p>Will now try to condition the UHV1400 furthest from the detectors at very low power according to SAES conditioning instructions.</p> <p>The advantages are unclear at present, but more temperature during baking should not hurt final vacuum level. Will re-activate all NEGs anyway.</p> <p> </p> <p>14:00 - Set power for all UHV1400 except those in the moving DSSD chamber to 20W. Some effects on both pressure and temperature. Will leave over weekend, start activation on Monday.</p>
