| 内容記述 | The Single Particle Irradiation to Cells (SPICE) facility has been constructed for biological cell irradiation, with the ability to deliver exactly defined numbers of ions into a small region within the area of an individual living cell. The SPICE is able to provide 3.4 MeV proton and 5.1 MeV alpha particle microbeams using a mono-bloc triplet quadrupole lens (Q lens), which is located just before the beam exit. We are currently adopting a scintillation counter that detects ions after passing through a biological cell, and a pair of electrostatic beam deflecting plates to realize single-ion irradiation. The output signal of the counter is fed to a computer-based scaler, and then a high voltage is applied for the deflecting plates to deflect the beam, once a defined number of protons has detected. The dosage precision of the single particle irradiation system has been tested for 3.4 MeV protons using 90 um thick CR-39 detector. The statistics of the etched pits number on the CR-39 has demonstrated that the single-ion irradiation system is capable of quantitative irradiation with the efficiency (the probability of which the number of traversal ion is equal to the preset value) measured to be 95.1% | |||||
