MOPLR059	Commissioning Plans for the ESS DTL	DTL, linac, emittance, proton	264

	The Drift Tube Linac (DTL) of the European Spallation Source (ESS) is designed to operate at 352.2 MHz with a duty cycle of 4% (a beam pulse of 2.86 ms, 14 Hz repetition period) and will accelerate a proton beam of 62.5 mA pulse peak current from 3.62 to 90 MeV. This article describes the commissioning strategy plans for the DTL part of the linac, techniques for finding the RF set-point of the 5 tanks and steering approach. Typical beam parameters, as proposed for commissioning purposes, are discussed as well and how the commissioning sequence of the tanks fits together with ongoing installation works in the tunnel.

MOPLR063	Development of H⁰ Beam Diagnostic Line in MEBT2 of J-PARC Linac	dipole, linac, vacuum, experiment	277

	In the Japan Proton Accelerator Research Complex (J-PARC) linac, H⁰ particles arising from collisions of accelerated H⁻ beams with residual gas are considered as one of the key factors of the residual radiation in the high energy accelerating section. To analyze the H⁰ and the accelerated H⁻ particles, the bump magnet system was designed and produced. The H⁰ beam diagnostic line consists of four horizontal bending magnets, non-destructive beam position monitor and wire scan beam profile monitor. In the 2015 summer maintenance period of the J-PARC, the new diagnostic line was constructed in the beam transport (MEBT2), which is the matching section from separated-type drift tube linac (SDTL) to annular-ring coupled structure linac (ACS). In the beam commissioning, we experimentally confirmed that the accelerated 190 MeV H⁻ beams are horizontally shifted as expected with the magnetostatic field simulation and the particle tracking simulation.
