In the framework of the METRICS project, nat/52Cr metal pellets were produced by SPS and then attached to a backing support composed of an Au thin inert layer bonded onto an Nb disc by SPS, as well.
The targets were irradiated using the ACSI TR19/300 cyclotron installed at the Sacro Cuore Don Calabria hospital for both target thermo-mechanical tests and purification process optimization.
A solid target dissolution system was manufactured starting from an automatic module already available on the market (Ekert&Ziegler), as shown in the Figure. Several separation and purification procedures, based on solid-phase extraction chromatography have been previously evaluated through preliminary bench experiments with natCr targets. An automatic module was assembled for irradiated target processing. The determination of the recovery % of Mn was performed by γ-spectrometry analysis, whereas the amount of Cr in the final 52Mn solution was determined by ICP-OES analysis.
