[BLAST_SHIFTS] Shift report, 15 June, 08:00-16:00

Everything ran fairly smoothly.

Changed WC STBY voltages to 2000 V from 3000 V with the idea that things
can cool down a bit more during injection. After this was able to put all
WC channels to 3800 for operating and tripping was only occasional.

If WC starts tripping again determine the channel which is tripping and
lower the operating voltage 100 V. If that holds for several fills raise
the operating voltage in 25 V steps so long as it doesn't trip frequently.

CODA hung twice and the HV R1 crate (TOF) had to be power cycled twice.

                                                  Cheers,
                                                          Douglas
