Apr 22: sqrt(sNN)=7.7 GeV maintenance and startup. Startup checklists are in the Thu Apr 20 Plan of the Day. Apr. 19, 39 GeV/n run continues to go well. ZDC rates for 39 GeV/n run, since start of the run. Apr. 12, 39 GeV/n ran well over this past weekend. STAR ZDC electronics had problems on Sunday. Otherwise both experiments are running well. ZDC rates for 39 GeV/n run, since start of the run. Apr. 9, 62.4 GeV/n ran well, ending at 8am Thursday morning. ZDC rates for 62.4 GeV/n run. Yesterday was spent setting up for 39 GeV/n. Physics began 3am this morning. Run 10 History Plan of the Day History |
