Magnesium diboride superconductive undulator

Abstract

The invention relates to a magnesium diboride superconductive undulator which comprises two lists of superconductive coil arrays which are vertically arranged at intervals in parallel. Each list of the superconductive coil arrays comprise a high conductive coil framework, 2n+1 magnetic conductive baffles which are arranged axially at intervals in parallel and surround the surface of the high conductive coil framework and 2n magnesium diboride superconductive coil windings wound on the surface of the high conductive coil framework and located between every two adjacent conductive baffles, wherein n is a natural number. The undulator further comprises a direct current power supply supplying power to the magnesium diboride superconductive coil windings. The current direction of the direct current power supply is arranged to enable magnetic induction strength generated by two adjacent magnesium diboride superconductive coil windings to be identical in magnitude and opposite in direction. The undulator adopts magnesium diboride superconductive materials, the superconductive critical temperature is higher, running temperature is higher, and refrigerating cost is reduced effectively. Simultaneously, the undulator adopts the integral type coil framework and improves cycle length accuracy of the magnetic field of the undulator.

Description

technical field [0001] The invention relates to a magnesium diboride superconducting undulator. Background technique [0002] An undulator is a device that generates a periodic magnetic field, and is a core component in synchrotron radiation devices and free electron laser devices. When the electron beam passes through the periodic magnetic field generated by the undulator, the emitted X-rays interfere, thereby obtaining high-brightness quasi-monochromatic light. [0003] At present, domestic synchrotron radiation light sources mainly use room-temperature rare earth permanent magnet undulators, whose main limitations are: the magnetic induction intensity it can achieve is low, and the adjustment of the magnetic field size is troublesome. The reason for the above limitations is that the normal temperature rare earth permanent magnet undulator is limited by the maximum remanence that the rare earth permanent magnet material itself can achieve, and the magnetic field strength ...
