	Nusano is developing a 50 MeV alpha (4He++) particle accelerator, primarily to produce medical radionuclides. The accelerator produces an average current of 3 mAe with 20 mAe average macro pulse current. This results in an average beam power of 75 kW, and an average beam power within the macro pulse of 500 kW. The beam profile at the exit of the DTL is approximately gaussian with a diameter (FWHM) of about 3 mm. Designing diagnostics for this beam is challenging, as any diagnostics that intercept beam will receive a very high heat load. A BIFM (Beam Induced Fluorescence Monitor) is being developed to measure beam profiles. Nitrogen gas is leaked into the beamline. Excitation of the nitrogen by beam particles is captured using an image intensifier. The signal generated is directly proportional to the beam current. A prototype system has been constructed and tested on a lower intensity alpha beam. First results indicate we can measure beam profile to a 100 µm accuracy. Production system is currently being designed. The Nusano accelerator can also accelerate 2H⁺, 3He++, 6Li3+, 7Li3+, and a few other heavier ions.

Nusano is developing a 50 MeV alpha (4He++) particle accelerator*, primarily to produce medical radionuclides. The accelerator produces an average current of 3 mAe with 20 mAe average macro pulse current. This results in an average beam power of 75 kW, and an average beam power within the macro pulse of 500 kW. The beam profile at the exit of the DTL is approximately gaussian with a diameter (FWHM) of about 3 mm. Designing diagnostics for this beam is challenging, as any diagnostics that intercept beam will receive a very high heat load. A BIFM (Beam Induced Fluorescence Monitor) is being developed to measure beam profiles. Nitrogen gas is leaked into the beamline. Excitation of the nitrogen by beam particles is captured using an image intensifier. The signal generated is directly proportional to the beam current. A prototype system has been constructed and tested on a lower intensity alpha beam. First results indicate we can measure beam profile to a 100 µm accuracy. Production system is currently being designed.
* The Nusano accelerator can also accelerate 2H⁺, 3He++, 6Li3+, 7Li3+, and a few other heavier ions.
