Wed Jun 11 08:37:48 2025, CB, PJW, Run 66
|
09:38
As Run 65, no changes, CRYRING operators attempting to improve beam intensity.
We should be able to keep running while they do, but there is a chance of some missed injections or other oddities. |

|
23:40
Offline anlaysis shows two clear peaks for DSSD1 and 2 at very low energies close to the threshold. One must be elastics and the other a noise
peak. |
