The negative hydrogen ion is the work horse ion in terms of medical radioisotope production world wide. This paper shall discuss latest developments in Penning ion source developments for cyclotrons utilizing internally produced H‾, largely for Positron Emission Tomography (PET) radioisotopes. In addition, evolution of the volume-cusp type ion source designs for H‾ production external to...
The RIKEN RI Beam Factory (RIBF) is working on the future upgrade project to increase the intensity of heavy ion beams, especially for the heaviest uranium beams which are particularly important in unstable nuclear physics research in the midst of global research competition. The charge conversion efficiency of the two charge strippers (He gas and rotating graphite sheet disk strippers) in...
A laser ion source is well-known as a high current and high charge state heavy ion source using laser ablation of solid materials. This is the only type of an ion source capable of producing ampere-class heavy ion beam using compact and simple ion source structure. However, it is difficult to transport and inject such a high current beam into the first stage accelerator, typically a radio...
At LANSCE, we are developing a new technique for measuring our H- beam energy by examining the decay photon spectrum distribution following neutralization. The photons emitted during the decay have well-known discrete energies. Therefore, the Doppler shift of their wavelength reveals the speed of the particles they came from, which allows for the precise calculation of beam energy. This method...
