Solenoids are filled, and nozzle has been regenerated. We are running 225
mA fill currents now, with a beam lifetime of about 28 minutes, and a DAQ
live time over 80%. This translates to over 500 C/hr. Ligit is perhaps a
bit low, so the target thickness may go up a bit more, and we may lose a
bit in lifetime and live time.
Plan is to run ABS hydrogen at 225 mA fill currents until Thursday morning
at 8 am. If the DAQ live time gets too low (less than 70%? -- something
that drops our accumulated charge below 450 C/hr), we can try turning off
the HV for the forward LADS walls, as suggested by Michael yesterday.
