Method for utilizing radio-frequency to accelerate electrons

Abstract

The method for speeding up electronic includes following steps. In the betatron, the guiding of the electron orbit is setup by the four blocks of the separated magnets. The snakelike sizing block for correcting the field is added to each side of the magnet. The four blocks of the separated magnets meet the following condition; the sum of the deflection angles of the magnet beam flow is 360 degree; the perimeter of the center orbit is the integral multiple of the radio frequency wavelength of the speeding voltage. The accelerating chains of the radio frequency single cavity speed up electrons longitudinally and respeatedly, making electrons do circumnutation about 5-10 cycles. In the acceleration process, the accelerating phases are slid within plus or minus 60 degrees.

Description

Technical field: [0001] The invention relates to accelerator technology, in particular to a method for accelerating electrons by using radio frequency. Background technique: [0002] As a radiation source, the electron cyclotron (MICROTRON) is a powerful competitor of the electron linear accelerator. However, due to the difficulty of track correction, it is not suitable for mass production. Later, the successful development of the runway-type electron cyclotron changed the microwave single resonant cavity into an acceleration tube of an electron linear accelerator, and divided the main magnet into two pieces, leaving a drift section of the electron orbit, so that the orbit correction situation improved slightly. . However, the cost has also increased significantly, weakening the competitive advantage. Some people envisage further separating the electron orbits, dividing the magnets into many pieces, placing them in the shape of petals, and adopting radio frequency coaxial...

However, the cost has also increased significantly, weakening the competitive advantage

Some people envisage further separating the electron orbits, dividing the magnets into many pieces, placing them in the shape of petals, and using radio frequency coaxial cavity to accelerate laterally, which reduces the cost and facilitates beam adjustment. This kind of accelerator is called Rhodotron, which means 'rose flower-shaped accelerator', but its structure is complex and its acceleration efficiency is low
