<p>D2000 thermocouples report temperatures around 100C (D2000 #1,2) and 120C (3,4). 1,2 are in the intermediate chamber, 3,4 are behind the moving arms. 3 is directly being the detectors.</p> <p>Wanted to flash ion elements in D2000, but SAES recommend >100C to flash.</p> <p>Followed SAES procedure / pre-sets to condition D2000 NEG elements while baking, but reduced temperature from 250 to 150 C (1,2) 140 C (4) and 130 C (3).</p> <p> </p> <p>No appreciable changes in temperature. Change in pressure quite apparent. Left elements at temperatures above. May consider increasing everything to 150 tomorrow assuming detector temperatures do not change.</p> <p>May also consider conditioning NEG elements in intermediate and DSSD wall chambers with 15W power (150C?) during baking as per SAES procedure. We never did this before, but we never baked as such low temperatures either. Will have to activate NEG elements after conditioning either way.</p>
