Thanks, that "much stronger" sounds promising.rnebel wrote:It's not all set yet, but the magnetic field will be much stronger than the WB-7 and so will the dynamic range.
Hope it gets built soon. Can't wait to hear the results!
Tom the 50 kJ is for an experimental set up - roughly 50 cm bore. Not very difficult. But the resistors need to be rated to take the pulse in one second.tomclarke wrote:Superconducting Magnets -
LHC at CERN use very many large SC magnets, with enormous total energy. The lost nearly a year from an "incident" when an SC connection had a resistance of a few uohm and heated up, boiling coolant, with disastrous effects. It took them a long time to clean the tunnel, and also develop new techniques to detect any future such problems and remove energy from the SCs before they heated up.
But 10H 100A seems very little. 50kJ is not challenging, a kettle on for 15s. And to quench in 1s 50kW peak is much easier than 50kW continuous.

The SC guys are working with 60 Hz AC in motor designs. They are also making line disturbance absorbers and limiters that go from SC to normal when the currents get too high.ravingdave wrote:It is my understanding that super conductors don't like rapidly changing fields. From what I have read, superconductors are charged up VERY slowly.Torulf2 wrote:The emergency energy storage for the energy in the supra conductor may be another supra conductor.
This risk of explosions may make fission-fusion hybrid with super conducting magnets unsuitable.
I haven't read anything which leads me to believe that energy can be dumped into a superconductor rapidly.
Does anyone else know if this is possible, and if so how ?

Will you be getting a bigger chamber?rnebel wrote:It's not all set yet, but the magnetic field will be much stronger than the WB-7 and so will the dynamic range.TallDave wrote:Are you able to share any details on WB-8 (e.g. size, magnet strength, changes to the interconnects, geometry changes, etc.)? From your earlier comments I'm guessing the emphasis will be on transport.
