Description
The Frankfurt Neutron Source (FRANZ) at the Institute of Applied Physics (IAP), Goethe University Frankfurt, is currently preparing for high-intensity proton beam operation up to 2 MeV. To support reliable transverse and longitudinal beam characterization downstream of the coupled RFQ–IH-DTL structure, a compact and versatile beam diagnostics section has been developed. For transverse profile monitoring, the setup combines an interceptive Chromium-doped Alumina scintillation screen with a non-invasive four-camera imaging system observing Beam Induced Fluorescence (BIF) in residual gas from two orthogonal projections. The optical readout utilizes single-board CMOS cameras, enabling automated background subtraction, 1D profile extraction, and 2D beam distribution analysis. Longitudinal parameters and beam energy are determined via Time-of-Flight (ToF) using two capacitive phase probes read out by dedicated gain and phase detectors. This contribution presents the instrumentation design, hardware selection criteria, sensor radiation tolerance considerations, and initial multi-angle profile measurements obtained during high-current proton beam operation.
