Analysis/Run Summary:
Run 3165 -- Slanted carbon target, 30 muA
Run 3166 -- Thick carbon target, 5 muA
Run 3167 -- Slanted carbon target, 30 muA. We had four HV trips for slot 13, L10.2 during this run, and L11.3 was running very high (over 1 MHz). So, the HV for L11.3 (N6 plane bar 4 right) was reduced from 2500 to 1900 during this run (see halog 353781).
Run 3168 -- Slanted carbon target, 30 muA. The HV for L11.3 (N6 plane bar 4 right) was returned to the original value of 2500 after this run ended (see halog 353788).
Run 3169 -- Slanted carbon target, 20 muA. At the end of the run, it was found that the GUI didn't accept the new value for the HV, so it was really at 1900 V for this run after all. And evidently, I didn't hear them correctly, because the HV should have been 2050 anyway! See halog 353793. Igor is working on the HV GUI...
Run 3170 -- Slanted carbon target, 40 muA. Igor fixed the miscreant GUI, and has set the HV for bar 4, right side, layer 6 to 2025 V during the beginning of run 3170 (see halogs 353797 and 353798). Has a noisy histogram for N6 plane right raw TDC3.
Run 3171 -- 10 cm LD target, 3 muA. Ended run because the rates too high.
Run 3172 -- 10 cm LD target, 1.5 muA. Rates are fine now (about 130 Hz). We have some strange histograms in run 3172, N6 plane right raw TDC3, and N6 Plane position 3. Is this from our noisy pmt? See halog 353815.
Run 3173 -- 10 cm LD target, 1.5 muA. We have some strange histograms in run 3172, N6 plane right raw TDC3, and N6 Plane position 3.
Run 3174 -- 10 cm LD target, 1.5 muA. In progress...
