    Beam off for a fopt

    High Voltages in EL and ER adjusted to put the energy loss peak about 1000+-100 chanels above the pedestal. Finished at 14:20.
    14:25 Computer crashed. Tried to reboot by resetting Trigger supervisor and ROC3 and ROC4. ROC4 would not reboot.
    Bodo suggest to make an access to recycle fast bus roc4 crate. Doug agrees. MCC has been notified.
    15:00 PM Ron and Bodo entered Hall A to Recycle ROC4 power supply.
    Started Run 1531 from the Hall as a check to be sure it is working.

    Run 1532 - Run 1533 Not useful runs.
    Run 1534; changed BB HVs for dE tubes, such that all signals will peak 300+-50 channels above pedestal.
    Run 1536; first good run to check changes of HV on E abd dE.
