Introduction (1)
MICE Run 1 covers ISIS operating period from February 5 through March 13, 2008
We have made considerable progress in getting ready for beam
power supply and magnet cabling well along
DC cables done; need grounding to operate
AC cables going in
interlocks being cabled
water connections completed on all upstream magnets
downstream magnets not yet done

Introduction (2)
Stages of program
Pre-commissioning
includes magnet testing and radiation survey
ISIS running; no MICE target
MICE target commissioning
includes operation of upstream beam line monitor
first measurements of yield vs. ISIS losses
Beam line commissioning (manual or with slow controls?)
includes operation of downstream beam line monitor
Detector commissioning (CKOV,...)
includes TOF0 and tracker if ready
Decay solenoid (“DS”) commissioning
if available
Preparation of “6” mm beam
evaluate yields

4. US Funding Status-Zisman
Pre-commissioning
Under way now
defining and checking magnet polarities
MICE NOTE MAGN-198 prepared (Apollonio, Flower, Tilley, MZ)
all magnet terminals marked (D1, D2, Q1-Q6)
dipoles tested back to power supply
quadrupoles tested only locally
To do:
test remaining magnet polarities at supply
get remaining services added (water, grounding, klixons, AC)
test all interlocks (thermal, water flow) at power supply
initial radiation survey(s)

5. US Funding Status-Zisman
No target
Necessary due to delayed delivery of second “validation” target system
unlikely that we will have permission to operate target during run-up period
Will ask for a bit of “semi-dedicated” time during ISIS production run
no guarantee we’ll get this
Can look at background rates on upstream detector
Can run magnets to look at stability and thermal behavior

6. US Funding Status-Zisman
Target
Awaiting target test procedure from Booth
also shift schedule
Can test
position reproducibility
reliability
triggering on ISIS clock (50/64 Hz rate)
losses in ISIS vs. dip depth
crude production estimates
Gather ammunition for discussion on loss rates

7. US Funding Status-Zisman
Beam Line
Operate locally unless slow controls are available
Start with dipoles only and positive polarity
protons (start with these) or pions
do not expect enough intensity for running negatives
use beam line detectors (upstream and downstream of DS)
can look at throughput (crudely)
look at alignment
Put on quads to see change in intensity
use optics for no-DS configuration
to be developed
look at steering and beam size changes
Do we test negative polarity?

8. US Funding Status-Zisman
Other detectors
Look at CKOV
will help distinguish protons from pions
Look at TOF0 or tracker, if available
Commission DAQ and get MLCR really operational

9. Commission Decay Solenoid
If we can get refrigerator and transfer line operational, will try to commission DS
unlikely, but worth a try
Would like to do warm polarity measurements if possible
Repeat beam line measurements if we get this far
these will represent “real” production estimates
