Alpha particle spectroscopy can serve as a valuable, isotope-specific, concentration monitoring tool in the harsh environment of molten chloride salts. In order to obtain good quality spectrum, a semiconductor detector needs to be brought as close to the analyzed sample as possible due to limited penetration capability of alpha particles. A thin actinide layer electrodeposited directly onto a semiconductor contact is an optimal solution to this obstacle. Techniques for obtaining a good quality, thin, non-dendritic deposits of thorium and uranium are under investigation. The nature of the periodic concentration monitoring also dictates that the deposit needs to be stripped away from the detector surface after each run. This is achieved by applying anodic voltage after the measurement. Techniques for efficient removal of the actinides from the surface, yet safe for the surface itself, are therefore discussed as well.
