	Developments of ECR intense light ion sources is an important research axis of the Laboratory of Study and Development of Accelerator at CEA-Saclay. Starting from the SILHI proton source in the 90’s to inject the IPHI accelerator, several SILHI-type sources have been realized and installed for high intensity proton or deuteron accelerators for international projects like IFMIF, FAIR or SPIRAL2. From 2011, we started new R&D program on high intensity ECR compact ion sources with the ALISES source family. The results obtained with the first ALISES source prototype gave us the main goals for the design of ALISES II source that runs several months on our 50 kV test bench BETSI and was dismounted at the end of 2016 to upgrade the test bench to 100 kV. But this source was never reinstalled and has been replaced by the ALISES III sources that runs on BETSI up to now. Recently, ALISES II ion source and its equipment is reassembled to be restarted on BETSI for beam characterization before sending it to MIRROTRON factory in Hungary as injector of proton for neutron beam facility. This paper describes the setup on BETSI and proton beam characteristics obtained by emittance measurements, spatial species proportion analysis with Wien filter and current optimization. Installation at MIRROTRON factory is also reported.

MOP04	ALISES v3 ion source in various configuration along the year	39
	O. Tuske, A. Dubois, O. Delferrière, Y. Gauthier, Y. Sauce CEA-IRFU, Gif-sur-Yvette, France
	ALISESv3 is a very compact light ion source that has been developed at CEA Saclay in 2018. The easy maintenance procedure of this source allowed us to test many different configurations. On the BETSI test bench equipped with an single Alisson Scanner and a pair a solenoid/deviator, we studied the extraction energy influence, we changed the number of electrodes in order to extract different kind of ions other than protons. This paper will describe briefly the ALISES 3 ion source and will present some results that we gathered in a year.

TUP04	Tests of a low-energy pepperpot based on a micro-channel plate for high current protons sources 4D-emittance characterization	94
	A. Thézé, B. Bolzon, A. Dubois, G. Ferrand, O. Tuske CEA-IRFU, Gif-sur-Yvette, France
	In the scope of high current protons sources characterization, the CEA is working on a 4D-emittancemeter based on the pepperpot technology. After some unsuccessful developments with phosphorous scintillators, we decided to test micro-channel plates (MCP) for measurements of proton beams at very low energy (typically between 50 and 100 keV). MCP are supposed to resist to proton beams at very low energy better than scintillators. This work presents some results for MCPs with an ALISES source on the BETSI test bench.

	In the scope of high current protons sources simulations, we tried to simulate the plasma chamber of the SILHI proton source with HFSS. This work focuses on the RF and multipactor simulation close to the boron nitride window.

TUP06	Wien Filter upgrade and measurement for BETSI test bench	101
	O. Tuske, O. Delferrière, Y. Gauthier, Y. Sauce, A. Dubois CEA-IRFU, Gif-sur-Yvette, France
	During first operation of SILHI in 1995 at CEA Saclay, a velocity filter diagnostic (Wien Filter) was installed on the LEBT, analyzing the 100 mA of protons at 95 keV. The device was used many years providing beam proportion measurements on the beam axis. Unfortunately, it was damaged while handling and was no longer working as intended. This paper describes the maintenance and upgrade of the diagnostic as well as the first beam proportion figures with ALISES 2 and ALISES 3 ion sources.
