Magnetic field distribution for two conductors (1. in superconducting state, but without current, 2. is with 100A current) The maximum field from one superconducting tape is about 0,02 T. Magnetic field distribution for two conductors, both with 100A current. Bmax is about 0,04 T. Taking into account the magnetic field value generated by those superconducting tapes, One can see, that Ic.max value is decreasing about 30-40%.
1,2 –Copper leads 6 – Exchanger of heat on a 40 K level 10 – Textile structural element, with HTS elements of current leads on it 7 – Exchanger of heat on a 4 K level
DECRIS Ion source is one of the most important elements of accelerators, for example nuclotron One of the most often used ion sources is ECR type ion source
Magnetic field gradient up to 100 T/m It can work continuos for several years Using crycooler cooling causes bigger automation and it is decreasing the cost of upkeep
Because of necessity of keeping up magnetic field homogeneity, often superconducting key blockers are used. They are closing the electric circuit after supply magnets. It freezes a magnetic flux generated by electromagnet. Umożliwiają odłączenie układu zasilania przy zachowaniu strumienia magnetycznego.
