Short Term Run Plan
Last Modified 02.06.17 by Maher Quraan.
Recommended beam tune files added by Robert MacDonald, 02.06.18
(These recommendations may change after Glen and Jaap do their beam
studies.)  If you change any beam elements (magnets, slits, jaws)
please save the result as a new tune!


Eff/noise/cross talk/multiplicity vs HV study for the PCs (outer wires):
========================================================================

Surface muons stopped in target with slits "closed" beam centered.
All DC thresholds set to 125 mV
All DC HV set to 1900 V
Use beam tune "m13dev_29p4_all.snap", which includes slit/jaw
settings.
Use the usual M coincidence for the trigger.

(1) Set all PC thresholds to 150 mV

Range the PC HV on all PCs (no control group needed) from 1600 to 2200 in
steps of 50 V.

Total: 12 runs, 200,000 events each.

(~40 minutes)

(2) Set all PC thresholds to 175 mV

Range the PC HV on all PCs (no control group needed) from 1600 to 2200 in
steps of 50 V.

Total: 12 runs, 200,000 events each.

(~40 minutes)

(3) Set all PC thresholds to 200 mV

Range the PC HV on all PCs (no control group needed) from 1600 to 2200 in
steps of 50 V.

Total: 12 runs, 200,000 events each.

(~40 minutes)

Total: ~2 hours


Eff/noise/cross talk/multiplicity vs HV study for the PCs (outer wires
target PCs):
=============================================================================

Surface muons with slits "closed" beam centered.
All DC thresholds set to 125 mV
All DC HV set to 1900 V
Same beam tune as before ("m13dev_29p4_all.snap").

(1) Set all PC thresholds to 150 mV

Range the PC HV on all PCs (no control group needed) from 1600 to 2200 in
steps of 50 V.

Total: 12 runs, 200,000 events each.

(~40 minutes)

(2) Set all PC thresholds to 175 mV

Range the PC HV on all PCs (no control group needed) from 1600 to 2200 in
steps of 50 V.

Total: 12 runs, 200,000 events each.

(~40 minutes)

(3) Set all PC thresholds to 200 mV

Range the PC HV on all PCs (no control group needed) from 1600 to 2200 in
steps of 50 V.

Total: 12 runs, 200,000 events each.

(~40 minutes)

Total: ~2 hours


Time zero and Alignment studies:
================================

120 Mev/c "wide" beam.
Use the tune file "m13dev_120_spray1.snap", which includes slit/jaw
settings.  If you use the prescaler, you can widen the slits and jaws;
if you do this, please save the new tune using the "m13_dev_all.req"
request file, and call it something like "m13dev_120_spray_wide.snap"
or something equally descriptive.

DC HV 1900 V
PC HV 2100 V
DC threshold 125 MV
PC threshold 175 mV

We will need to get enough data, again, for computing time zero.

- A total 1 million events at 0% B2 setting.
- A total of 3 million events +3% B2 setting.
- Atotal of 3 million events -3% B2 setting.

These sum runs will provide a Huge amount of data for both
translational and rotational alignments. We will also use these runs
to look at efficiency/ cross talk (etc) variations from wire to wire
at these nominal chamber settings.  Of course, previous studies might
suggest slightly different HV settings or thresholds.

Total: 10 hours.


Beam rate studies (patrec efficiency, etc):
===========================================

- Surface muon tune anolgous to magnet on tuning with muon beam
stopped at center of target.
Use the tune file "m13dev_29p4_all.snap", which includes good slit and
jaw settings.

DC HV 1900 V
PC HV 2100 V
DC threshold 125 MV
PC threshold 175 mV

- Beam rate at 1 KHz, 1 million events.
- Beam rate at 2 KHz, 1 million events.
- Beam rate at 3 KHz, 1 million events.

These runs can also be used for finding time zero and for plane
alignments.

Total: ~ 5 hours.


Total Time for all studies listed: 24 hours (I hope I added
correctly)!
