Laser muon sources : concepts and challenges

Muons, standard constituents of elementary particle model with the mass of 207 times
electron mass, are available nowdays in cosmic radiation or can be produced by
accelerators [1]. The progress in laser technolology - availability of high-intensity and
highrep systems [2] , inspires the study of their potential production as tertiary particles in
laser-matter interaction. There exists several posibilities how to achieve this goal :
Direct muon Electron / photon driven systems High-energy complex
production processe 1.1 Electron-electron 1.2 Electron-nucleus particle sources
(electromagnetic collisions collision
processes)
Photon-driven systems Weak pure lepton
2.1 Photon-photon 2.2 Photon-electron sources
collisions collision
Muon production via Proton / ion driven systems Medium energy
pion decay (nuclear 3.1 Flying pion 3.2 Stopped pion sources
processes) decay decay (surface
muons)
In this contribution, results of a suitability study in this area considering concrete ELI
Beamlines systems (HELL, ELIMAIA, P3 ) will be presented. Main attention will be given
to the processes 2.1, 2.2 and 3.2. The first calculation of the proces 1.2 [3] evidently
overestimates the muon yield in a real experiment. Detection and parameter measurement
of muons in this process should be the first task for the experiment, results from the study
[4] are not convicing. The most effective process, alowing the development of applicable
muon source could be the mechanism 3.2. Nevertheless, its possibility supposes the
availabilty of a laser-driven proton / ion beam with energy of several hundred MeV. The
energy of this order is necessery also for oncological applications, the progress in this
intensively studied area will pave also the route for laser muonics. Proposal of an applicable
source based on the process 3.2 wil be presented. Some potential applications of laser-based
muon beams will be mentioned.
