The IFMIF-EVEDA accelerator will be a 9 MeV, 125 mA (CW) deuteron LINAC with the purpose of validating the technology that will be used in the future IFMIF accelerator. In such low energy and high current prototype accelerator, any device intercepting the beam could be destroyed. Thus, non interceptive profile monitors will be installed inside of a Diagnostics-Plate and along the High Energy Transport Line. CIEMAT group investigates a profile monitor based on the fluorescence of the residual gas. A high neutron and gamma flux environment (due to high deuteron beam current) stands for a hostile environment for most of electronic devices and fibers. The design must guarantee not only good spatial resolution but a reliable operation in such environment. Hence, different options for detectors, optical windows, fibers and shielding concepts have been considered to overcome these aspects. Transverse profilers will be used as well as a tool to perform emittance measurements through quad-scans. In this contribution, the design of a transverse profiler prototype for EVEDA, together with a brief discussion about mechanisms that can play a role in profile falsification will be presented.
