Superconducting Magnets in Spectrometers of High Energy Particles

Shishov Yu. A.

A retrospective review of superconducting magnets for spectrometers of high energy particles is given. The magnets are classified according to the purpose of the spectrometers and the winding shape. The data on thermostabilization and electrical protection of the winding are presented. The design features of magnets for different application are described. The first large superconducting solenoids were constructed for set-ups with hydrogen bubble chambers. The further progress was related with the development of spectrometers for colliding beams, where the solenoids with radiation-transparent walls were used. The dipole and toroidal magnets were applied in the spectrometers alongside with the solenoids. The construction of some of them is also considered in the review. A special class of polarizing solenoids is used in polarized targets. The spectrometers with magnets of different winding shapes have been manufactured for astrophysics studies. An original radiation-transparent solenoid and a dipole magnet with a cryocooler, are given as an example. The perspective to develop the magnets is related with using high temperature superconductors (HTS). The status of HTS ribbon and solenoid production process is presented.
