“…The post-accelerators in the Radioactive Ion Beam facility (RIB) at Variable Energy Cyclotron Centre (VECC) comprise Radio Frequency Quadruple (RFQ) Linear accelerator [1,2] followed by three IH-Linac modules [3,4]. The RFQ accelerates 𝐴/𝑞 = 14 ions from 1.75 keV/u to 100 keV/u while the energy at the end of the third Linac module is 400 keV/u.…”

This paper reports the design, development and testing of a 3.0 kW, 37.8 MHz radio frequency (RF) amplifier system that has been built by combining four solid-state amplifier modules of 1.0 kW each. The design philosophy and test results of individual components such as driver amplifier, final amplifier modules, power divider/combiner, dual directional coupler (DDC) with system control and interlocks are discussed in detail. Compact 4-way Wilkinson power divider and combiner have been implemented using combination of 50 Ω coaxial cables at this lower frequency of 37.8 MHz. It provides better isolation between the ports and also have high power handling capability. The amplifier has been tested with existing 37.8 MHz quarter-wave resonator type re buncher in the Radioactive Ion Beam (RIB) facility. The performance test results of developed RF system with Re buncher cavity have been presented in this report.

A: A minimally-interceptive bunch length detector system is being developed for measurement of longitudinal dimension of the bunch beam from RFQ of the radioactive ion beam (RIB) facility at VECC. This detector system is based on secondary electrons emission produced by the primary ion beam hitting a thin tungsten wire placed in the beam path. In this paper we report the design, development and off line testing results of deflector cavity together with its RF sysytem. The deflector cavity is a capacitive loaded helical type λ/2 resonator driven by RF source of 500 W at 37.8 MHz solid state amplifier, realized by combining two amplifier modules of 300 W each. The measured RF characteristics of the resonator, such as frequency, Q value and shunt impedance have been found to be reasonably good and close to the analytical estimation and results of simulation. The design philosophy and test results of individual components of the amplifier are discussed. The test result upto full power shows a good harmonic separation at the individual module level and this is found to improve further when modules are combined together.The results of high power performance test of the deflector cavity together with amplifier are also reported.
