The 32P implanter is a compact ion accelerator that delivers a ion beam of the radioactive isotope phosphorus 32. The ion beam can be used to label material with 32P. Such materials can be used for biomedical or material scientific applications where 32P can be used as a tracer.
The ion beam is generated by an electron-cyclotron resonance ion source (ECRIS) which contains 32P, which has been generated by neutron activation. The typical acceleration voltage is 60kV, which allows to implant, depending on the target material, into depths down to 100nm. The ion beam can be raster-scanned across an area of approximately 10 cm × 10 cm, enabling homogeneous implantation into that area. The activity of the target can be determined online during the implantation using a home-build setup.
