Regulation of the waveguide coupling factor of standing wave linear accelerator allows to adjust the value of accelerated current, keeping the reflected RF power close to zero. This ensures the most efficient use of RF energy and absence of overvoltage in the waveguide elements. The paper presents studies results for various methods of coupling factors regulation with continuous wave (CW) normal conducting linear accelerator used as an example. The results of calculations and measurements on the mock-up of the accelerating structure are presented.

Bunch shape monitors, based on a transverse RF-scanning of secondary electrons, are used for measurements of particles longitudinal distribution in bunches at different linear ion accelerators. The phase resolution of such monitors depends crucially on accuracy of fabrication and tuning of RF-deflector, thus preliminary simulations of its electrodynamic characteristics are of importance for subsequent commissioning of the monitor. Simulations of some basic operational electrodynamic parameters and results of experimental measurements are presented.
