	To cope with the demands of the Facility for Antiproton and Ion Research (FAIR) for high current operation at the GSI Heavy Ion Linear Accelerator UNILAC non intercepting methods for transverse beam profile measurement are required. In addition to intercepting diagnostics like Secondary Electron Emission Grid (SEM-Grid) or scintillating screens, the Beam Induced Fluorescence (BIF) Monitor, an optical measurement device based on the observation of fluorescent light emitted by excited nitrogen molecules, was brought to routine operation. Starting with the first installations in 2008 and consequent improvements, successively six monitors were set up in the UNILAC and in the transfer line (TK) towards the synchrotron SIS18. BIF is used as a standard diagnostic tool to observe the ion beam at kinetic energies between 1.4 and 11.4 MeV/u. Beside the standard operation mode where the gas pressure is varied, further detailed investigations were conducted. The BIF setups were tested with various beam parameters. Different settings of camera, optics and image intensification were applied to improve the image quality for data analysis. In parallel, the light yield from different setups was compared for various ions, charge states, beam energies and particle numbers.

	The Facility for Antiproton and Ion Research (FAIR) poses new challenges for standard beam instrumentation like precise beam imaging over a wide range of beam parameters, radiation hardness, etc. A new, fully FAIR-conformal system for standard scintillating screen based beam diagnostics was developed at GSI. To cover a wide range of foreseen applications, a new technical solution was required for the upcoming FAIR High Energy Beam Transport lines and Rings. The newly developed system including digital image acquisition, remote controllable optical system and mechanical design, was set up and commissioned with beam. CUPID (Control Unit for Profile and Image Data) is based on the CERN Front-End Software Architecture (FESA) to control beam diagnostic devices. The FESA class for the digital GigE camera (IDS uEye UI-5240SE-M, CMOS type) acquires the images and pre-processes the optical data as required by the geometry of the setup (rotation, stretching). The performance of the system reaches more than 15 frames per second with one connected client. If desired, the raw image data can be written to a file for offline analysis. Additionally, dedicated FESA classes access industrial Programmable Logic Controllers (PLCs) for a reliable slow control solution using the CERN IEPLC library. Camera control, timing, as well as power supply and reset options for up to eight digital cameras are realized by the in-house developed Camera Power Supply controller CPS8. We report on first results with the novel system during routine beam operation. In addition, we describe first operating experiences with new radiation-hard camera (Thermo Fischer Scientific, CCIR MegaRAD3) installed at the SIS18 extraction point with high radiation level.
