3. Work required for April test (1)
Stator delivered by Manchester was not built to specs! Cannot use.
Coil winding in progress.
Body parts manufactured.
Alternative potting scheme possible (improve heat flow).
Glass cap & flange for readout planned.

4. Work required for April test (2)
Final dimensions of shaft clarified with Oxford.
Major work on stator  lack of technical effort in Sheffield. Oxford agreed to assemble shuttle.
Meeting in Oxford next week to finalise details (shaft, target, stop, magnets, alignment & readout vanes; cleaning).
Steel tube – replace with Ti later.

5. Work required for April test (3)
Control hardware & software developed with no Hall magnet commutator – being debugged.
Pseudo-current-controller built.
Boards being crate-mounted for transport and reliability!
Tests & monitoring.

8. University of Sheffield
Work required for June
Shuttle with Ti shaft.
Interface to ISIS control & timing.
Improved analogue electronics.
Optimised control.
DAQ & monitoring software.

9. Future Plans (for October)
Hardware changes based on experience.
High current drive circuitry:
Two days of meetings with Daresbury electronic engineers (DL, Sheffield).
Basic design is sound. No commercial alternative.
They will enhance drive to ?80 A?
Power supply – capacitor bank and charger.
June results will feed into design requirements.
