TI - Development of Novel Non-Destructive 2D and 3D Beam Monitoring Detectors at the Bern Medical Cyclotron J2 - Proc. of IBIC2020, Santos, Brazil, 14-18 September 2020 CY - Santos, Brazil T2 - International Beam Instrumentation Conference T3 - 9 LA - english AB - The Laboratory for High Energy Physics (LHEP) at the University of Bern is developing novel beam monitoring detectors for the 18 MeV medical cyclotron in operation at the Bern University Hospital (Inselspital). A 2D non-destructive beam monitor - named Pi2 - was developed, based on a thin aluminium foil coated with P47 scintillating material and a camera. It measures the transverse position, shape, and intensity of the beams for several applications, as radiation hardness or radioisotope production studies. This detector allows the processing of data in real time and a reconstruction of the transverse phase space. Based on the Pi2, a first prototype of a 3D beam monitoring detector - named Pi3 - was conceived, constructed, and tested. It is based on the same scintillating foil mounted on a movable support with a miniaturized camera. The Pi3 detector allows for the study of the beam evolution along a beam line, even inside a magnet, and the reconstruction of the beam envelope. In this paper, we report about the design, construction and beam tests performed with these two detectors. Further developments will be also presented and discussed.
