We have developed two techniques for microscopic ion beam imaging and profiling, both based on scintillators, particularly suitable for applications in deep lithography with protons (DLP) or with heavier ions. The first one employs a scintillating fiberoptic plate and a CCD camera with suitable lenses, the second makes use of a small scintillator optically coupled to a compact photomultiplier. We have proved the possibility of spanning from single beam particles counting up to several nA currents. Both the devices are successfully exploited for on-line control of proton beams, down to a beam size of less than 50 μm, in the framework of DLP application. [Copyright &y& Elsevier]

Discusses the development of devices which are based on scintillator detectors and photosensors, for beam monitoring of EXCYT radioactive ion beams. Benefits of these monitoring devices; Concern expressed over the production of radioactive ion beams; Requirements of beam monitoring devices; Use of scintillators by physicists; Details on design of the devices.

The need of diagnostic tools for low energy–low intensity beams has lead us to the development of a series of suitable devices, in order to perform imaging, profiling and identification of ion beams, with particular care for the EXCYT radioactive beams. The peculiarities of these devices are compactness, handiness and good performance for very low intensity beams (Ibeam<105 particles/s), in a range of energy from 50 keV up to 8 MeV/A.

Abstract: We describe a cheap yet effective beam collimation system capable of providing square apertures from 1mm down to about 10μm. The tunable part is driven by two manual micrometers, one controlling the shape the other the size, which could be immediately replaced by high precision stepping motors should remote control be needed. The aperture was calibrated by means of a simple home-made laser diffraction system which allows a considerable precision. The collimation system was used to produce low-divergence beams of oxygen and protons, in order to test the position sensitivity of a silicon microstrip telescope detector. [Copyright &y& Elsevier]

The EXCYT facility at the INFN-LNS aims to the production of radioactive ion beams to be post-accelerated by a 15 MV Tandem. The primary stable heavy-ion beam (up to 80 MeV/amu, 1 pμA) is supplied by a K-800 Superconducting Cyclotron, which has been operating in a stand-alone mode, by means of the new axial injection beam line, since December, 1999. The magnets of the primary beam line have been aligned and most of the components of the mass separator have been purchased. Different types of Heavy Ion Target–Source (HITS) systems have been built and are here described; in particular, a microwave ion source fully designed and manufactured at LNS has been assembled and successfully tested. Finally, low-intensity beam diagnostics is also ready and reliability tests are under way. [Copyright &y& Elsevier]
