Description

The J-PARC linac is operated with design peak current of 50 mA from 2018. Further, a higher beam current is being investigated for future projects at J-PARC. For operation with such a high beam current, it is required to understand parameters of beam especially in a medium energy beam transport (MEBT1) line between the 3-MeV RFQ and the 50-MeV DTL. MEBT1 is a 3-m-long transport line to match the beam to the DTL and produce a macro pulse configuration for a 3-GeV RCS. In this paper, recent measurements in MEBT1 and in a test bench of RFQ will be presented. (author)
