A blumlein line-driven linear induction accelerator and its voltage adjustment method

Abstract

The invention discloses a linear induction accelerator driven by a Blumlein line and a voltage adjusting method thereof. The linear induction accelerator driven by the Blumlein line comprises a high voltage generator (1), a main switch (2), the Blumlein line (3), a transmission line (4) and an induction acceleration cavity (5). An adjustable inductor (6) is arranged between an outer tube (301) and an inner tube (302) on one side of the output end of the Blumlein line (3). The linear induction accelerator driven by the Blumlein line and the voltage adjusting method thereof have the advantages that on the basis of a traditional linear induction accelerator driven by the Blumlein line, the adjustable inductor of a certain inductance value is used for connecting the outer tube and the inner tube which are coaxial and are placed on one side of the output end of the Blumlein line, when the inductance values of the adjustable inductor are different, the slopes of the top of the acceleration voltage waveform of the accelerator can be different, and therefore the purpose of adjusting the flat-topped acceleration voltage is achieved. The acceleration voltage waveform can be adjusted conveniently, and the structure of the device is simple and reliable.

Description

Technical field [0001] The invention relates to the field of linear induction accelerators, in particular to a linear induction acceleration device driven by Blumlein lines and a voltage adjustment method thereof. Background technique [0002] The linear induction accelerator is a high-current pulse accelerator with a modular structure. Such as figure 1 When the pulse width of the linear induction accelerator is short (on the order of 100ns), the pulse power source widely uses the coaxial Blumlein line to form the pulse, and its main switch is placed between the middle tube and the outer tube of the Blumlein line. The existence of the accelerating cavity naturally constitutes the charging path of the coaxial line in the Blumlein line, so there is no inductive connection between the outer tube and the inner tube of the Blumlein line; in addition, because the Blumlein line is charged, the current flowing through the induction accelerating cavity and the main The pulse current is o...
