VSWR Adjustment for ACS Cavity in J-PARC Linac
Journal of Physics: Conference Series, 2019 Abstract In the Japan Proton Accelerator Research Complex (J-PARC) linac, negative hydrogen beams are accelerated from 190 MeV to 400 MeV by Annular-ring Coupled Structure (ACS) cavities. The RF input coupler of the ACS21 cavity, which is the twenty-first (the last) accelerating cavity in the order of beam acceleration, had a ...

CIRCULAR FRACTAL MONOPOLE ANTENNA FOR LOW VSWR UWB APPLICATIONS [PDF]
Progress In Electromagnetics Research Letters, 2008 A new circular ultra-wideband fractal monopole antenna based on descartes circle theorem (DCT) with elliptical iterations is presented. The proposed fractal design is optimized for return loss below −15 dB. The basic structure is slightly modified to ensure an overall smooth current distribution limited by the junction point nature of the fractal ...
