Abstract
To realize and test advanced accelerator concepts and hardware, a beamline is being reconfigured in the Linac Extension Area (LEA) of APS linac. A photo-cathode RF gun installed at the beginning of the APS linac will provide a low emittance electron beam into the LEA beamline. The thermionic RF gun beam for the APS storage ring, and the photo-cathode RF gun beam for LEA beamline will be accelerated through the linac in an interleaved fashion. In this paper, the design studies for interleaving lattice realization in APS linac is described with initial experiment result
Highlights
New acceleration technologies for compact accelerators, such as laser-driven plasma wakefield accelerators, beamdriven plasma wakefield accelerators and structure-based wakefield accelerator (SBWAs), are rapidly developing many synergies
Since the requirement for injection into the particle accumulator ring (PAR) was satisfied, the Advanced Photon Source (APS) linear accelerator has been operated with minimal beam loss through the linac after filtering lowenergy electrons in the alpha magnet
Because of the significantly different properties of beams produced by rf electron gun (RG) and photocathode gun (PCG), setting up a single linac lattice that is suitable for both beams is an extremely challenging task
Summary
New acceleration technologies for compact accelerators, such as laser-driven plasma wakefield accelerators, beamdriven plasma wakefield accelerators and structure-based wakefield accelerator (SBWAs), are rapidly developing many synergies. The experimental study for these new acceleration technologies requires a large scale facility. The existing large facility must be considered for the experimental study on new acceleration technologies. Such an experimental study requires a long time without interruption to user operation (original purpose of facility). The thermionic rf electron gun (RG) provides the electron beam that is accelerated through the linac, injected into the particle accumulator ring (PAR), cooled, and transferred to the booster synchrotron. It is accelerated, and injected into the APS storage ring.
