Novel accelerator concepts will play an important role in future accelerators for high energy physics. As examples for a possible applications, we want to explore two scenarios, relevant for present research in high energy physics: the generation of relativistic single electrons with gigahertz repetition rate for dark matter search, and the rapid acceleration of muons with GV/m accelerating fields for experiments at the energy frontier.
GHz Rate Electrons
Dark matter appears to be more abundant in our universe than visible matter, yet its composition and properties remain largely unknown. Indirect detection experiments make use of a well-known initial state, and search for energy and momentum unbalance in the detector. The generation of single electrons with relativistic energies would supply a clean initial state. As the coupling constant to standard model particles is very small, a high repetition rate of the experiment is absolutely necessary for these planned experiments. In this workshop, we will explore the use of dielectric accelerating structures, directly driven by a high-repetition rate laser. Such concepts could lead to energy-efficient accelerators for indirect dark matter search experiments.
Rapid Muon Acceleration
Muons are promising particles for future colliders at the energy frontier, because their higher mass leads to a significant reduction in energy losses through synchrotron radiation in comparison to electrons. Muons are, however, unstable, and they need to be accelerated rapidly to relativistic energies to avoid their decay. Plasma wakefield accelerators, which have demonstrated GV/m accelerating fields, appear a natural candidate for this rapid acceleration.
This invitation-only workshop will combine experts from the fields of high energy physics with laser and accelerator physicists. We are aiming at an open exchange of ideas, and we will leave ample time for discourse and discussions. Please contact the conference chairs if you are interested in participating in this workshop!
