    18:32 DAQ crashed, (end run 1871. reset.
    19:05-19:30 Tests for happex: increase fan frquency to 72 Hz.
    rebooted ioc, since teh JT control didn't work.
    19:13 asked raster to be 5x5 (MCC units)
    then 6x6 MCC units.
    19:30 raster back to 2.7x2.5 mm
    Tried to set fan speed back to 60 HZ, did not work. Reboot ioc and re-start GUI, still not working. Stay at 72 Hz and
    continue data taking.
    20:05, Beam off, RF problem, may take 10 minutes. Then another 30 minutes, then ...
    21:15 beam back
    23:30 MCC called that diffuser waterflow fault.
    page then called ed Folts. He is coming.
    Per Run coordinator instruction, change to kin. 13.
