Abstract:

Development of accelerator structures that can sustain acceleration gradients in the range of 150 MeV/m are required in order to build a future multi-TeV collider with an energy reach beyond present or planned electron-positron colliders. A two-channel dielectric wakefield accelerator is to be developed that could have the potential to satisfy that need. A coaxial structure consisting of two dielectric pipes surrounded by a conductor is being analyzed so as to design (Phase I) and test (Phase II) a wake field accelerator driven along its outer channel by an annular charge bunch whose wake fields accelerate a test charge bunch moving along its inner channel. This structure can have the advantages of a high transformer ratio, favorable stability, and accelerator gradients in a mm-scale version of several 100 MeV/m induced by a single few-nC drive bunch. Computations were carried out to predict performance of coaxial dielectric wake field accelerator modules that can be tested using facilities at Argonne National Laboratory. Stability of the high-current drive beam and the low-current test beam was analyzed and found to be adequate for the range of experiments that are planned for Phase II. Experiments will be carried out using facilities at Argonne National Laboratory to measure test beam acceleration, structure transformer ratio, and beam stability. Further computations will be made to refine designs for a future TeV-scale version of this two-beam accelerator. Commercial applications and other benefits: Development of structures that can sustain high accelerating gradient without an undue frequency of breakdown, and which can be the basis for a future multi-TeV electron-positron collider, can hasten the day when the multi-TeV collider will be built, and thus hasten the day when the many commercial companies will have an opportunity to obtain the multi-million dollar manufacturing contracts for the accelerator structures.
