| Publication Abstract: | Accelerator-based searches for dark matter are aiming for high sensitivity and need an experimental setup with high luminosity. This field of research is often called intensity frontier physics. One of the best motivated portals of interaction between dark matter and ordinary matter is a dark photon which could be observed as a resonance in invariant mass of the decay products. Electron-positron collision is known to be the cleanest process for such a study. In this paper we propose a scheme for a collider which allows for a luminosity of a few orders of magnitude higher than could be obtained in a conventional symmetric collider and with a few times higher accessible mass than is possible using a positron beam and a fixed target approach. The key concept is based on asymmetric energies: a high energy circulating positron beam and a low energy high intensity electron beam, and optimization of the beam interaction region. We present here a configuration of the collision region of the 10 MeV electron and 4 GeV positron beams. |
