30 kW Beam Commissioning of the High-Intensity Proton Accelerator IPHI: Experiments, Simulations and Space Charge | |
|
||
| Over the past few years, CEA-Saclay has been actively engaged in R&D activities focused on high-intensity proton and deuteron beams. In particular, the high-intensity proton injector IPHI has been designed and developed with the primary objective of accelerating a continuous beam of 100 mA to 3 MeV. This machine consists of a high-intensity ECR ion source, a low-energy beam line, a 352 MHz RFQ, and a medium-energy transport line equipped with diagnostics. The commissioning of the IPHI facility started several years ago with a proton beam operating at a low duty cycle (0.1%) and a current of 65 mA. Since then, significant progress has been made, resulting in an accelerated beam power exceeding 30 kW. Following this achievement, a neutron production target with a polyethylene moderator was installed and successfully operated. In addition, extensive measurements have been conducted to thoroughly characterize the beam accelerated by IPHI and its transport through the beam lines. We have developed an end-to-end numerical model of the IPHI accelerator and validated it against experimental data. The simulation results are compared with the measured values and discussed in detail. | ||
