We have been developing on proton beam generation with a Laser ion Source (LIS). A LIS has its uniqueness in providing various species of ion beams only by changing solid material target which is irradiated by high intensity pulsed laser. The methods to provide heavy ion beams such as Au or Fe solid target were already established, but there has been no attempt to produce proton beam with LIS....

The space charge compensation process is important in order to transport ion beams with high perveance from the source to the RFQ. In particular, not fully compensated beams may develop halo and emittance growth at the entrance of the RFQ. The signal of incomplete compensation is the presence of a significant residual potential (in the range of 5% or 10% of the uncompensated potential). In...

A new type of laser ion source was developed to produce low charge state positive, negative, and cluster ions by constricting a plasma in a narrow cylindrical volume formed by the target ion material. The basic operation of the ion source involves the ablation of a spot within a cylindrical hollow target by a Q-switched laser. The focused laser strikes the inside surface of the target at a...
