Application of the transfer matrix for tuning the CSNS-DTL

In the construction of a drift tube LINAC (DTL),many factors caused during the fabrication and assembly of the structure cells cause the electric field distribution not as the same as the design curve.To solve this problem,the traditional way is to solve the equation of Slater's perturbation theorem to obtain the electrical field variation due to local frequency shift.However,that is very difficult under complicated conditions.Since the field perturbation equation is similar to the particle's transverse mot...
