Overview
• Then
• Now
• Simulations
• Thermal Calibration
• Project plan
• Outstanding Issues
Mon Oct 27 LC-ABD, Dundee 6
• Magnetic simulations at DL
• Vector Fields Opera with Elektra rotation solver
• Magnet modelled as two coils
• Calculate expected power losses from eddy currents as wheel rotates, and resistive force this generates
• Spoked modelling taking place at RAL ( J. Rochford )
Mon Oct 27 LC-ABD, Dundee 8
The plan is still the same…
• Sweep in parameter space of B-Field, Rotation Speed and Immersion (1 T, 2000 rpm, 50 mm)
• Observation of kicks as spokes traverse field
• Measurement of eddy currents by torque and direct heating ( Lei Zang: PhD student, Liv )
• Study of rotor-dynamics (LLNL: accelerometers)
Mon Oct 27 LC-ABD, Dundee 9
Just waiting on:
• Safety sign-off
• Cage interlocks
• …Immersion calibration
• …Water and power re-connection to magnet
• …Cooling nozzle design and implementation
