TI - Beam Commissioning of the J-PARC Mr After Its High-Repetition Rate Upgrade J2 - Proc. of HB2023, Geneva, Switzerland, 09-13 October 2023 CY - Geneva, Switzerland T2 - ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams T3 - 68 LA - english AB - At the J-PARC MR, a project to increase beam power with faster repetition rates is currently underway. With large-scale hardware upgrades in Jul. 2021 to Jun. 2022, the MR operation cycle for the fast extraction mode has been shortened from 2.48 s to 1.36 s, and beam commissioning at this operation cycle is in progress now. The MR first aims to achieve a beam power of >750 kW at this operation cycle, and then finally 1.3 MW by further shortening the operation cycle to 1.16 s and with a higher beam intensity of 3.3 x 10¹⁴ ppp. This paper describes the beam commissioning status including the future prospect.
