	The SPIRAL2 linac is now successfully commissioned; H⁺, 4He2+, D⁺ and 18O6+ have been accelerated up to nominal parameters and 18O7+ and 40Ar14+ beams have been also accelerated up to 7 MeV/A. The main steps with 5 mA H⁺, D⁺ beams and with 0.6 mA 18O6+ are described. The general results of the commissioning of the RF, cryogenic and diagnostics systems, as well as the preliminary results of the first experiments on NFS are presented. In addition of an improvement of the matching to the linac, the tuning procedures of the 3 Medium Energy Beam Transport (MEBT) rebunchers and 26 linac SC cavities were progressively improved to reach the nominal parameters in operation, starting from the classical ¿signature matching method¿. The different cavity tuning methods developed to take into account our particular situation (very low energy and large phase extension) are described. The tools developed for an efficient linac tuning in operation, e.g. beam energy and intensity changes are also discussed.

	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.

	SNRC in Israel is in the process of constructing a neutron production accelerator facility called SARAF. The facility will utilize a linac to accelerate a 5 mA CW deuteron and proton beam up to 40 MeV. In the first phase of the project, SNRC completed construction and operation of a linac (referred to as SARAF Phase I) which included an ECR ion source, a Low-Energy Beam Transport (LEBT) line, and a 4-rod RFQ. The second phase of the project involves collaboration between SNRC and Irfu in France to manufacture the linac. The injector control system has been updated and the Medium Energy Beam Transport (MEBT) line has been installed and integrated into the infrastructure. Recent testing and commissioning of the injector and MEBT with 5 mA CW protons and 5 mA pulsed Deuterons, completed in 2022 and 2023, will be presented and discussed. A special attention will be paid to the experimental data processing with the Bayesian inference of the parameters of a digital twin.
