Measurements of the targeting accuracy of the Gray Laboratory charged-particle microbeam
The charged-particle microbeam provides a unique opportunity to precisely control both the dose to individual cells and the localization of dose within the cell. In the Gray Laboratory, both the performance of the detection system and the targeting system has been assessed for 3.5 MeV 3 He 2+ ions....
