                Evening Shift 4 Jan 00
On Shift: Rick T, Marj
Also present: Rick K, Wah, Elliott, Jason H
Hours of beam available at all intensities: 0
Hours of beam available at nominal intensity: 0
Hours of E799 data (special runs not included): 0
Hours of special runs (laser scans, muon runs...): 0

Accounting of lost time:
MI quad failure, est. as of 16:00 is 12 hrs
Runs ended this shift:

Run 15395 Cosmics
Run 15397 Cosmics

Tapes brought to FCC this shift: none

Accesses during shift:

Elliott and Jason, to replace power strip on ET system.
Marj and Rick T, to look at laser repeater signals

Overview of shift:

No beam, little activity. Ran cosmics most of the shift, trigger hung
often. Cycled laser crate repeater many times, KFREND many times.
Still a puzzle

Description of Shift:

run spill time comment
15395 16:00 MI quad failure...12 hr estimate. Continue
                       cosmic run to keep system alive
                17:05 Elliott and Jason make access to replace ET power strip
                17:20 Run manager checks in...he suggests we phone the
                       Mojove desert.
                17:40 Jason and Elliott out of access.

15395 19:15 End run so Rick K can add C13 trigger in preparation
                       for future tests

                19:30 Note that we have only one more bottle of Ar-ethane.
                       Have new bottles been ordered? Email sent to Dave N

15397 21:00 Start new cosmic run after Rick K is done with tests
                 21:10 KTEVANA errors, ordinal number mismatch, KFREND
                       KTEVANA errors again, power cycle laser crate repeater
                 21:20 Pipeline errors, reset pipeline
15397 22:15 KTEVANA errors again, Rick suspects laser crate,
                       cycle power yet again
                 23:00 Rick K has installed ET-board calib trigger for
                       KAMI tests, see log book XXIII, pg 182 for details,
                       including how to kill it if it creates trouble.

                 23:10 New estimate for beam is 3AM

                 23:30 RickT and Marj make access to look at laser crate
                        repeater for problems...but we didn't see anything
                 00:00 Hand over to owl shift
Items to Follow up on Next Shift

       Mike A. has installed new BA voltages for
       muon run, need to return to nominal after muon run.
