keyword=Target: beam compensation not working
During Target initial tests with beam (as we ramp it up) we end up with
seeing the target not regulate properly. Goes too cold with beam on, does
not increase the HP heater enough. PID problem?
Call Dave Meekins (poor guy..)
It seems the "beam compensation" has some sort of software issue. We note
that it appears that the wrong dE/dx was loaded for the cell properties;
Dave has fixed this, but it still does not seem to be working. Dave
suspects a software issue, and turns off beam compensation for now. Should
be OK for the weekend - it will just not compensate as rapidly as ideally
to a beam trip... will live with this for now...
