AFC Module progressPresented by
Wing Lau --with input from AFC group members
Action Who Progress made status
Implement central repository for drawings -- need detector information to add to official drawing
WL Basically complete. On-going liasing with Mississippi on CKOV1 drawings; with Tortora on Calorimeter etcDiffuser still to be addedHyperlink to drawing gallery is now available
Done.
Instrumentation for absorbers must be specified and incorporated into design (temperature sensors, liquid level sensors, …)
SI Proposal now available (see Shigeru’s summary talk) and will be discussed among the AFC group as an on going action for Absorber R&D
Done
Define absorber heater implementation YI / SI Ditto
Done
Continue working to define worst-case magnet forces and collect magnet design notes into design report
MG/YI/ SY
Yury and the team at RAL has now completed that work. Stephanie completed the FEA on forces and displacements. We are now homing in on the rail and anchoring design details
Done
Check if a 1600mm gap between AFC & Tracker matching coils
WL/ UB
Ullisee has completed the calculations and advised that either gap distance (800mm or 1600mm) is acceptable as far as forces and current density are concerned. However, the group has a preference to the 800mm gap.
Done
Revise absorber vent pipe size to make it adequate for He case
WL Agreed to increase this to 15mm diameter. Drawing being updated
Done
Get RAL seismic design criteria and verify that designs meet them
WL/ PD
This is not considered significant as RAL site has relatively low floor response. A static “G” of 0.3 would be sufficient for all components with a natural frequency of above 33Hz.
Complete.
Status of Progress
Action Who Progress made status
Evaluate stresses at module interconnect flanges and bolts
SV Steve Verostek had done detail FEA on bolt / flange connection and the work is still on-going
On-going
Define RFCC module tie-in to rail system SV This is now in he hands on the RAL design team
On-going
Work out gusset arrangement to transfer CC forces to RFCC module vacuum shell.
SV Await Mike Green to finalise the Cold Mass support arrangement before deciding on how and where to put these gussets
On-going
Evaluate the need for redundant LH2 relief paths
EB / TB
This is part of the on-going R&D activity on the Hydrogen System R&D.
On-going
Evaluate merits of cryocooler heater vs. 3-stage cooler w/o heater
MG Concluded that this is no longer an option for our current design
Done
Evaluate absorber heat load with more realistic assessment of surrounding temperatures (is proposed MLI adequate?)
EB/MG/SY
Thermal model set up. Elwyn and his team are making progress on this
On-going
Finalize interface between radiation shield and detector module- must forces be transmitted
WL Stephanie has done the calc. Forces and displacement s at modules are acceptable for the 7 cases being considered.
Done
Consider participation in KEK and/or Fermilab absorber tests (some coordination maybe called for)
YI / SI
MICE Absorber R&D will be carried out at KEK for the 1st absorber. We are still in discussion with Shigeru on whether the thermal test of the 2nd & 3rd absorbers should be done at KEK or RAL.
On-going
Evaluate magnet interaction during quench-- does one quench induce others
EB / MG
Work is by and large complete. It shows that the 3 focus coils should be powered in series. The 2 Coupling Coils could be powered up either in series or separately.
Done
Raise Change note on the radiation shield design
SY / WL

•This note presents the optic solutions for MICE Step III for a large number of different running conditions.
•Two gap distances between the two spectrometers are considered, 800 mm and 1600 mm.
•For the 800 mm gap, a table with forces and peak fields on coil surfaces for the worst case scenarios is
attached, courtesy of H. Witte
•For the 1600 mm gap, all currents in the MICE coils are equal to or less than the worst case currents of the 800 mm
gap.
•Hence, for the 1600 mm case, forces and peak fields are also lower than the ones in the 800 mm case.
•In conclusion, currents, peak fields and forces both in the 800 mm and in the 1600 mm gaps are within
tolerances.

Concluding Comments on Quenches
• The focusing and coupling magnets will have passive quench protection. The detector magnet will likely have an active quench protection system.
• The three focusing magnets should be in series.
• Each coupling magnet should have its own power supply to reduce the charge time.
• Like detector magnet coils can be put in series.
• A coupling coil quench will quench the rest of MICE. A focus coil quench will not quench a coupling coil.

Task Description
An AFC Module window that was damaged during machining was used to test a non-contact measurement method. A standard CMM was also used for comparison. All measurements were made on both sides of the window with the thickness being determined indirectly from the two sets of data. Measurements consisted of 12 radial slices at 15º increments. The center 80 mm of the window is damaged.
Measurement Methods•Standard CMM with low contact force•Vision machine with medium magnification lens•Vision machine with high magnification (not yet complete)
Summary of Results•Best data obtained from CMM measurement•Vision machine data shows more scatter•Good portion of window is within 40 m of design thickness
Standard CMM Measurement Vision Machine Measurement
Discussion
• The vision machine works best when measuring horizontal, smooth surfaces
• The combination of a sloped surface and machining grooves in the window is likely responsible for the data scatter
• Preliminary results indicate that the higher magnification lens may provide better results than the medium lens
• Overall, the best results are achieved using contact CMM
• The following method would provide the highest accuracy: Contact CMM using a low-force tip and appropriate
approach angle resulting in no window deflection The window mounted vertically to allow a single set-up

Obtain magnet force on AFC module during Stage IV test when only one AFC module is placed between the two detector solenoids
EB / SY
Initial guess is that the force is in the region of 30 tons. Force calculation will be carried out to verify this number. A new temporary bridging plate will be designed for the Stage IV test
New action
Revised Action list
Stage IV arrangement – 2 tracker solenoids + 1 AFC module in between
Magnet force of approx. 30 Tons due to asymmetric quench of magnets
Magnet force of this magnitude may cause excessive bending here
