Relativistic Klystron Two-Beam Accelerator*
نویسنده
چکیده
Relativistic klystrons are being developed as an rf power source for high gradient accelerators applications which include large linear electronpositron colliders, compact accelerators, and FEL sources. In a relativistic klystron two-beam accelerator (RK-TBA), the drive beam passes through a large number of rf output structures. High conversion efficiency of electron beam energy to rf energy can be achieved in two-beam accelerators using reacceleration of the bunched drive beam. We have conducted experiments which studied rf power extraction in an RK-TBA and have prepared a demonstration in which a modulated beam's energy is boosted as it passes through induction accelerator cells.

Preliminary studies of beam dynamics in a relativistic klystron were done to support a design study for a 1 TeV relativistic klystron two-beam accelerator (RK-TBA), 11.424 GHz microwave power source. This paper updates those studies. An induction accelerator beam is modulated, accelerated to 10 MeV, and injected into the RK with a rf current of about 1.2 kA. The main portion of the RK is the 30...
