Tapes brought to FCC this shift:

Accesses during shift:

Overview of shift:

Muon runs all shift long. There is no hadrons due to NM2S3 power supply

Miguel studies DC plateau
Elizabeth works on MA and REG HV
Rick K works on filter code and trigger configrations

Description of Shift:

run spill time comment
13473 00:00 BEAM_MU_4E12 is running 10pm yesterday
109 00:28 Stop the run

Beam Control called and asked about our plans.
We informed them that we will ask 2E12 beam ,
11 batches later this shift. They expressed
concern that they will not be able to do that.
It is more likely that intensity will be lower
at 3 batches only

13474 00:40 BEAM_MU_4E12 started

We've been taking muon runs for a while. It is
possible that muon data will fill up the disks and
the button "DISK" turns red in ONLINE SPLIT window.
If this happens, page Sydney (722-6849)

00:50 Stop the run

13475 01:00 BEAM_MU_4E12 started

01:05 Main Control called. There is an indication of
water leak in NM2S3. Beam is off. They are investi-

01:15 Gas Checklist is done.

01:27 It is verified, there is an internal water leak
in power supply of NM2S3. Repairs will start
in the morning. Before that we will have muons.
There will be no hadrons.

01:50 The run stopped

13476 01:55 BEAM_MU_4E12 started

"CACHER" button turns red in ONLINE SPLIT window.
It goes green few minutes later. This is a false
alarm according to Sydney (who was paged anyways)

02:03 The run is stopped

13477 02:05 BEAM_MU_4E12 started

13478 02:20 BEAM_MU_4E12 started

13479 02:35 BEAM_MU_4E12 started

02:40 Main Control called and told us that they've been
delivering beam in 11 batches for last 0.5 hours.

13480 02:45 BEAM_MU_4E12 started

13481 03:15 BEAM_MU_4E12 started

13482 03:27 BEAM_MU_4E12 started

13483 03:40 BEAM_MU_4E12 started

13484 03:50 BEAM_MU_4E12 started

Miguel finished DC studies

13487 04:50 BEAM_MU_4E12 started.
This is going to be long muon run
(goal is to get 2M events)

Follow up Notes on Previous Shift

Items to Follow up on Next Shift

1. The alignment crew for DC will be here at 8:00am
2. Get in touch with Brian Lavoy as soon as alignment crew is here.
3. get 4413 CAMAC discriminator from PREP (call x3447 first)
