  CEA Saclay Irfu is in charge of the major part of the con­trol sys­tem of the SARAF-LINAC ac­cel­er­a­tor based at Soreq in Is­rael. This scope also in­cludes the Ma­chine Pro­tec­tion Sys­tem. This sys­tem pre­vents any dam­age in the ac­cel­er­a­tor by shut­ting down the beam in case of de­tec­tion of risky in­ci­dents like in­ter­cep­tive di­ag­nos­tics in the beam or vac­uum or cool­ing de­fects. So far, the sys­tem has been used suc­cess­fully up to the MEBT. It will be tested soon for the super con­duct­ing Linac con­sist­ing of 4 cry­omod­ules and 27 cav­i­ties. This Ma­chine Pro­tec­tion Sys­tem re­lies on three sets: the MRF tim­ing sys­tem that is the mes­sen­ger of the "shut beam" mes­sages com­ing from any de­vices, IOxOS MTCA boards with cus­tom FPGA de­vel­op­ments that mon­i­tor the Sec­tion Beam Cur­rent Trans­mis­sion along the ac­cel­er­a­tor and a Beam Des­ti­na­tion Mas­ter that man­ages the beam des­ti­na­tion re­quired. This Des­ti­na­tion Mas­ter is based on a mas­ter PLC. It per­ma­nently mon­i­tors Siemens PLCs that are in charge of the "slow" de­tec­tion for fields such as vac­uum, cryo­genic and cool­ing sys­tem. The paper de­scribes the ar­chi­tec­ture of this pro­tec­tion sys­tem and the ex­changes be­tween these three main parts.
