Poster

TEM-like superconducting quarter wave resonator (QWR) is adopted for the lowest optimum beta (0.047) section of the RAON. For the proper acceleration of heavy ions in QWR, 3 kW, 81.25 MHz RF power is supplied through coaxial couplers. For acceleration of heavy ion beam in the superconducting linear accelerator, the Low-Level RF (LLRF) should have feedback control of accelerating field and...

The IFMIF/EVEDA Accelerator Prototype (LIPAc) is currently under construction in Rokkasho (Japan). LIPAc will generate a 9 MeV deuteron beam at 125 mA current with a 100% of duty cycle, and it will serve to validate the final IFMIF accelerator concept. The radiofrequency (RF) Power System, which is being integrated by CIEMAT (Spain) and its partner companies and institutes, consists of 18...

the RAON accelerator complex is planned in Korea for nuclear science research, and solid state power amplifiers will be used to provide superconducting cavities with rf power. The RAON main accelerator is composed of a normal conducting injector and a superconducting linac. The SC linac uses 3 types of SC cavities which are QWR, HWR and SSR. The SSR is divided into two families of low and high...

Poster

A new generation of Arc Detectors was developed at CERN for the Linac4. For reliability reasons the detectors do not use optical fibres. Each sensor head is equipped by four independent photo detectors with optional two "blind" sensors for environments with high radiation background. Since the first introduction in 2012 the detector design has been finalised, the housing ruggedised and made...
