1. CTOF gains and trigger parameters were changed in preparation for the
coming RG-K run. The changes doesn't affect the total trigger rate or data size.
See details in https://logbooks.jlab.org/entry/3626566

2. New trigger version:
trigger_v22_1_no_dc_roads.trg

3. The beam current was increased to 50 nA.
Trigger rate is around 18 kHz, data rate 420 MB/s, live time 93%.
We still have room to go to 55 nA. Will try later today after accelerator break that will start at 13:00.

4. The downstream rate limit was changed to 700000 due to the change of the beam current.

5. We expect downtime starting 13:00 for several hours (2-4).
The hall will be closed. However if you need access to hall just let me know.
