Checked lamp intensity. Intensity was high at 16.1 Mw/cm2. Also power supply was alarming. Peaked and adjusted lamp position with X/Y/Z knobs on lamp house. Checked and recalibrated lamp power supply by matching P/S readout to external meter and setting the setpoint to 15 mW/cm2. Power supply display does overshoot but does settle at 15 Mw/cm2. The intensity itself is very stable and settles at 15 MW/cm2 immediately as measured on the external meter. Will have FSE look at the power supply when he is in to do the PM,s in December.
