The aim of the AMIT cyclotron is to deliver an 8.5 MeV, 10 μA CW proton beam to a target to produce radioisotopes for PET diagnostics. Such a small cyclotron poses some challenges to the diagnostics design due to its small size. Two sets of diagnostics have been designed, each one aiming at a different phase of the machine lifecycle. During normal operation the stripping foil and the target will be used to measure the current, a dual transverse profile monitor based on a scintillating screen and a Fluorescence Profile Monitor will measure the beam position and the transverse profile. During first stages of commissioning the dual transverse profile monitor and the target will be substituted by an emittance monitor based on a pepperpot. A movable interceptive Beam Probe will be located inside the cyclotron to give information about the beam during acceleration. Additionally, a test bench for the characterization of the beam right after the exit of the ion source has been built with different instruments to measure the beam current and the transverse profile. In this paper the present status of the design, simulation and tests of the diagnostics for the AMIT cyclotron are described.

  Luminescent screens hit by accelerated charged particle beams are commonly used as beam diagnostics to produce a visible emitted light, which can be sensed by a camera. In order to investigate the characteristics of the luminescence response of several scintillators, the beam shape and the observation of the transverse position, experiments were done with different low intensity proton beams produced by two different test benches. This study is motivated by the need to identify scintilla-tor materials for the development of a 4-dimensional emittancemeter which will allow the characterization of the beams, in particular the emittance measurement (size, angular divergence). This paper describes the experimental setups and our investigations of the optical properties of various scintillating materials at two different proton beam energies respectively about 30 keV and 3 MeV. The light produced by these screens is characterized by yield, flux of the emitted light versus the beam intensity, time response, and long life-time and they are compared.
