“…This work is a first step to make an informed choice. We focused our development to activation studies for beam energy below 20 MeV, using the proton cyclotron CYRCé (Cyclotron for Research and Education) [12], available at the IPHC laboratory. This value corresponds, indeed, to physics models threshold in main Monte Carlo codes.…”

Nuclear activation is the process of production of radionuclides by irradiation. This phenomenon concerns particle accelerators used in various fields, from medical applications to industrial ones, both during operation and at the decommissioning phase. For more than three decades, the possibility of using cyclotrons for nuclear power generation and nuclear waste reduction has also been discussed, i.e. in the case of Accelerator-Driven Systems [1]. The radioprotection and dismantling issues of accelerator facilities, that have been raised recently, is even more potent for such installations. In our study, we are particularly interested in the activation due to secondary neutrons produced by (x,n) reactions, mostly (p,n) occurring in the accelerator’s components. This work focuses on the study of the radioactivity induced in various materials (V, Sc, Tb, W, Ta) irradiated by fast and thermal neutrons, in two different scenarios: through direct irradiation -with an AmBe sourceand around an operating cyclotron at the CYRCé facility (Strasbourg). A broad Monte Carlo study including FLUKA, GEANT4, PHITS and MCNP simulation has been performed, with and without a FISPACT-II coupling, to estimate the reaction rates and to trace the induced radioactivity in samples of known composition. The results of the simulations are compared with the values extracted in two dedicated experimental campaigns in which activated samples underwent high resolution gamma-ray spectrometry.

The ability to switch ion beams on and off quickly is a key point in proton therapy that can be achieved by means of electrical actions. A beam chopper system has first been developed to fulfill this function on the TR24 Cyclotron of the Cyrcé Platform at the IPHC Laboratory. In addition, the capability of discarding one ion beam bunch over two is of great interest in the context of the CMS (Compact Muon Solenoid) detector as it allows us to make tests close to the LHC (Large Hadron Collider at CERN) bunch repetition rate (40 MHz), the cyclotron RF frequency being 85.085 MHz. A second kicker (the so-called RF kicker) has been developed and installed in place of the first one to fulfill both requirements. This article discusses the sizing and characteristics of these two systems that were consecutively installed on the injection line of the TR24 cyclotron. The first system reported uses fast static high-voltage switches while the second one uses an RF resonator to either populate or depopulate the phase acceptance of the cyclotron. To our knowledge, this second system used in this specific context has not yet been reported in the literature.

“…The results obtained from the experimental campaign allowed, first, the conception and the development of the Common Beam Transport Line (CBTL) transporting the protons from the cyclotron out of the vault to a five-exit dipole located in the experimental area. Once the CBTL defined, beam dynamics investigations were performed and the PRECy and CMS beamlines were developed (figure 1) [7].…”
