continuing Q2_j50 kinematics
15:53 start run 1800
16:50 ROC14 crashed before the end of run 1800 at 914988 events, no end of run record written.
16:53 reset roc14
16:56 start run 1801
17:04 Q1 tripped off - because of He lvl faults. level was at 50% let it ramp down
stopped run 1801 at 137K events
17:29, Q1 has been reset to proper field - We needed to make the last small field adjustment manually because it overshot the desired setting by a small amount.
17:29 start run 1802
18:36 end run 1802, 1M evts
18:36, start run 1803
19:39 end run 1803 1M events
19:39 start run 1804
20:43 endrun 1804 1M evts
20:44 start run 1805
21:04 - beam off due to ioc crash/ per mcc
21:15 - start moving the left spec to 75 deg and P0=0.8 for ztg runs. We had to hit the green button (left bogies reset button) in the middle room to bring up the left bogies control screen.
22:03 - left momentum is now 0.8 GeV/c, spec at about 49 deg and moving
22:25 - 95 uA beam back, still moving specL
22:30 - finished spectrometer motion - there are very few numbered floor marks on the left spec for these large angles. One has to count the marks from numbered marks.
runs 1806, 1807 are junk
22:39 start optics run 1808, 9 foil carbon, raster is off, specL at 75.005 deg, 800 MeV/c.
24:00 Beam off for Maintenance
