The Arronax Public Interest Group (GIP) uses a multi-particle cyclotron to perform irradiation from a few pA up to hundreds of uA on various experiments and targets *. To support further low intensity usage and extend the beam time structure required for experiments such as pulsed experiments studies (radiolysis, proton therapeutic irradiation) and high intensity impact studies, it has been devised a pulsing system in the injection of the cyclotron. This system combines the use of a chopper, low frequency switch, and a control system based on the new extended EPICS network. This paper details the pulsing system adopted at Arronax, the last results in terms of time structure, various low intensity experimental studies performed with alpha and proton beams and the dedicated photon diagnostics.
