Physical design of superconducting magnet for ADS injection I

Superconducting solenoid magnet prototype for ADS Injection I had been designed and fabricated, and also had been tested in liquid Helium state inside a vertical Dewar in Haerbin institute of Technology in Nov. 2012. The design current is 210A, when the test current reached 400A no quench occurred, the solenoid magnet was forced to quench by the embedded heaters. The integral field strength, leakage field at the nearby upstream and downstream superconducting spoke cavities all meet the design requirements. At the same time, it also checked the system reliability of the vertical test Dewar and the quenched detection system. The superconducting magnet prototype has accumulated valuable experiences for the coming batch magnets production and cryogenic test.
