Progress Report of the SPICE (Single Particle Irradiation system for CEll) in NIRSHitoshi Imaseki,National Institute of Radiological SciencesThe ion-microbeam technique adapted to cellular irradiation becomes currently interested in the field of radiation biological effects research. By using this method, it is prospected that important quantitive analysis in the field of radiobiological can be done.From 2000, we started to specify the Single Particle Irradiation system for CEll (SPICE), whose optical design bases the achievement of scanning microbeam PIXE system in NIRS, and installation was finished in 2003. From that time, we have been developing the system.The feature of this system is that it uses the triplet quadrupole lens for beam focusing and voice coil motor for the movement of the target stage, uses Proton (3.4MeV) and Alpha (5.1MeV), and is upward atmospheric radiation.The end goal of is that we put the both of the beam size and the targeting accuracy within 2um, and the irradiation speed above 2000 cells/hour.
