A radioactive silver beam was produced by RIALTO in November for the N-RI-22 experiment on TETRA. The figure shows the spectrum of a silver beam of mass 123 sent to the TETRA decay station. For this measurement, the TETRA neutron counter was also surrounded by an HPGe and a plastic scintillator to detect beta electrons. Two acquisitions of 100 cycles of the tape with 2 seconds of collection and 2 seconds of decay were made with (red spectrum) and without (blue spectrum) laser, in order to compare the production of radioactive Silver.
