Secondary implantation of 51Cr and 48V radioisotopes into plastic surfaces for nano-TLA study

Indirect recoil implantation following a nuclear reaction is a technique used to activate the surface of materials that cannot be directly activated by a charged particle beam. This research focuses on the indirect activation of Kapton ® foils, which serves as a model of plastic or plastic coated surface activation. The alpha particle primary beam, produced by a cyclotron accelerator hits a stack of titanium and Kapton ® interlaced foils. The implanted activity in the Kapton ® foils is presented as a function of the primary beam energy for two separate implanted radioisotopes 51 Cr and 48 V, having suitable nuclear parameters for tracing in engineering experiments.
