Alan Bigelow works on projects related to the single-particle single-cell microbeam irradiation system at the Radiological Research Accelerator Facility (RARAF) at Columbia University. With the current generation of the microbeam system, Alan's projects are centered on cellular dynamic imaging and on expanding the range of ion species emitted by the particle accelerator. More specifically, Alan has developed and installed a multiphoton microscope for the microbeam endstation and has built a laser ion source as an option for the terminal of the new HVE 5 MV Singletron particle accelerator at RARAF.
