keyword=T7 rate stability for last 12 hrsthis plot is the T7 rate normalized to BCM average (x3 gain) versus run number. the y-scale is Hz per µA (therefore we expect a T7 rate of 490 Hz for a 14 µA beam current). the data spans the last 12 hrs from run 1251 to 1282.
the numbers were pulled from the end of run summaries by hand. as you can see, the normalized rate was very stable until about run 1267. (1260 was also strange for some reason)
this might be correlated to the T1 rate instability in the left arm. both issues will be investigated during the access @ 0900 that will coincide with beam studies.
