Dear Everyone,
Let's cancel today's RC meeting due to scheduling conflicts, we'll resume tomorrow.
Yesterday's maintenance day included successful repairs of the AHDC readout electronics and the recent sector 1 trigger issues, and the IPM2H01 cavity was also tuned. Beam restoration was good and quick and included a Moller run measuring 83% polarization. RG-L production running started around 10pm, with 325 nA on He-4.
Today's plan is to continue production running as is, with only a brief study by the injector group in between runs to see if our laser power can now be decreased without sacrificing beam halo/quality. Also, our Faraday cup trigger rate is fluctuating oddly, used for offline background studies, to be investigated.
Regards,
Nathan as RC
