	For 10 years our Institute CEA Saclay Irfu has been involved in several in-kind collaboration contracts with ESS at Lund (Sweden) and one of these includes the test of numerous cryomodules in a dedicated test bench designed at Saclay. The cryomodules start to be assembled cavity per cavity in a clean room and must be low pressure pumped, without adding particles and always in a clean room. This is the purpose of the mobile pumping units for particle free beam vacuum. These units are also designed for vacuum automatic procedures, residual gas analysis and can provide conformity reports. Furthermore, a connectable industrial touch panel is added for a mobile operator interface. Only few buttons have to be panel touched by an operator to start automatic procedures in order to get a very high quality vacuum. The embedded control system is PLC based and manages many communications, especially with the spectrometer embedded in the unit. Only one CPU manages all the communications (Profinet, Profibus, TCP-IP ASCII and even Modbus) and sensors or actuators are controlled by four input-output cards. This small-scale control system is innovative because it is versatile, very convenient to use, deploy and maintain. Nine mobile pumping units are operational and continuously used, frequently moved to different locations, controlled locally or remotely and are still reliable. The paper describes the control architecture and functionalities of this small but full of possibilities device.

	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.
