- Access to add more ice.
- 9:00 PM: Running now at 800 V with a 145 uA leakage current. Tried again to reduce the rate by moving S10 to 0.5 mm, but saw no particles on the DUT! Now to 2mm to verify that the DUT still exists. Don't want to upset the operators, will wait for shift change to go back to 1mm.
- 00:26: asked to increase slits from 1 to 2 mm. Particle count before was ~10 (but double peak, so ~5) and after is ~30 (still double peak, so ~15). We got this from looking at the cluster multiplicity in the 3rd telescope plane (basically no noise).
- 1:10: asked for the S10 slits to be moved out the whole way (100 mm) so that we can quickly scan the sensor.
- 2:35: LCLS beam down for a user (they didn't tell us...had to ask when we noticed no beam). They say they will 'give up in 30 min' and revert back if they can't get the configuration they want. Powered off the HV in order to preserve the temperature.
