STUDY OF ELECTROSTATIC SEPTUM BY LOW-Z MATERIAL FOR HIGH INTENSITY PROTON BEAM

We examined a feasibility of a low atomic number (low-Z) material as a septum part of an electrostatic septum device (ESS) in the slow extraction at a high intensity proton accelerator. We succeeded to fabricate robust wires from carbon fibers by applying a twisting technique. We produced a testing machine of the ESS using the carbon wires.
