	Before approaching the micro-loss monitor concept, we propose to present the high intensity Linac for which the R&D program was done, LIPAc (Linear IFIMIF Prototype Accelerator). This later is the feasibility accelerator demonstrator for the International Fusion Materials Irradiation Facility (IFMIF). IFMIF aims at providing a very intense neutron source (10¹⁸ neutron/m2/s) to test materials for the future fusion reactors, beyond ITER (International Thermonuclear Experimental Reactor). LIPAc (1.125 MW deuteron beam) is in installation progress at Rokkasho (Japan). Then, we will focus on the feasibility study of the beam optimization inside the SRF Linac part. Commissioning of such high beam intensity has to be done with a different approach based on detection of micro-losses, CVD diamonds, set inside the cryomodule linac.

THPM8Y01	Beam Energy Loss in a β=0.09 SRF HWR Cavity for 100 mA Proton Acceleration	cavity, HOM, ion, factory	567

	Funding: Work supported by National Basic Research Project (No.2014CB845504) There’s presently a growing demand for cw high current proton and deuteron linear accelerators based on superconducting technology to better support various fields of science. Up to now, high order modes (HOMs) studies induced by ion beams with current higher than 10mA and even 100 mA accelerated by low β non-elliptical Superconducting rf (SRF) cavities are very few. One of the main HOM related issues of the SRF linac is the HOM-induced power. HOM power is the important part of beam energy loss which is used to estimate the cryogenic losses. In this paper, we compare the beam energy loss induced by 100 mA beam passing through a β=0.09 HWR SRF cavity calculated from time domain solver and frequency domain cavity eigenmodes spectrum method.
