  The first phase of the SPIRAL2 project includes a driver and its associated new experimental areas (S3 and NFS caves). The accelerator, located in Caen (France), is based on a linear solution composed of a normal conducting RFQ and a superconducting linac. Intense primary stable beams (deuterons, protons, light and heavy ions) will be accelerated at various energies for nuclear physics. The beam intensity monitoring is a part of the operating range control of the facility. A high level of requirements is imposed on the intensity control system. In 2013, a failure mode and effects analysis (FMEA) was performed by a specialized company helped by the GANIL’s Electronic group. This paper presents the analysis and evolutions of the electronic chain of measurement and control.

  The first part of the SPIRAL2 project entered last year in the end of the construction phase at GANIL in France. The facility will be composed by an ion source, a deuteron/proton source, a RFQ and a superconducting linear accelerator. The driver is planned to accelerate high intensities, up to 5 mA and 40 MeV for the deuteron beams. A monitoring system was built to measure the beam energy on the BTI line (Bench of Intermediate Test) at the exit of the RFQ. As part of the MEBT commissioning, the beam energy will be measured on the BTI with an Epics monitoring application. At the exit of the LINAC, another system will have to measure and control the beam energy. The control consists in ensuring that the beam energy stays under a limit by taking account of the measurement uncertainty. The energy is measured by a method of time of flight; the signal is captured by non-intercepting capacitive pick-ups. This paper describes the BTI monitor interface and presents the system evolution following the design review.
