keyword=ep energy measurement online result
The ep background was crappy. Rate about 1.2 Hz. This background was
presumably due to the "unusual" tune of the A-line that we have at this moment. The moller quad power supply is still dead.
At any rate, I took a long ep run (after quite a few accelerator problems -- RF).
The spectra were not very nice. The micro strips had lots of events with large multiplicity and the co-planarity was mediocre at best. It would certainly be best if our friends in France had a look.
The very preliminary -- online -- number I extracted was:
energy = 4809.0 +- 2.7 MeV
I have no feel how much we should trust it.
