“…Cooling of the heat load in the target material analog to Ref. [29] may be an option for future higher repetition rates. The produced muons, unlike electrons and hadrons, penetrate the target material without suffering noticeable scattering and absorption.…”

We analyze þ À pair production generated by high-energy electrons emerging from a laserwakefield accelerator. The þ À pairs are created in a solid thick high-Z target, following the electron accelerating plasma region. Numerical estimates are presented for 1 to 10 GeV electron beams which are expected to be reliable in the nearest future. Reactions induced by the secondary bremsstrahlung photons dominate the dimuon production. According to our estimates, a 20 pC electron bunch with energy of 1 (10) GeV may create about 100 (5000) muon pairs. The produced AE can be used in studying various aspects of muon-related physics in tabletop installations. This may be considered as an important step towards the investigation of more complicated elementary processes induced by laser-driven electrons.

Abstract. At the superconducting electron linear accelerator ELBE at Forschungszentrum Dresden-Rossendorf the neutron time-of-flight facility nELBE has become operational. Fast neutrons in the energy range from 200 keV to 10 MeV are produced by the pulsed electron beam from ELBE impinging on a liquid lead circuit as a radiator. The short beam pulses of 10 ps provide the basis for an excellent time resolution for neutron timeof-flight experiments, giving an energy resolution of about <1% at 1 MeV with a short flight path of 5 m. By means of a "double-time-of-flight" setup the (n,nâγ) cross section to the first excited state of 56 Fe has been measured over the whole energy range without knowledge about cross sections of higher-lying levels. Plastic scintillators were used to detect the inelastically scattered neutron and BaF 2 detectors to detect the correlated γ-ray.

“…For reasons of calibration and statistical accuracy of the determined spectra or reaction cross-sections, a mean beam energy fluctuation of 10-3 is needed. Also, the production of channelling X-rays [2], infrared light (FELBE user facility, [3]) and neutrons [4] at ELBE suffers from instabilities of the primary beam. Not only the spectral distribution of the secondary radiation is directly connected to the beam energy, but also the impinging position and angle at the target may be affected if the alignment is not purely free of dispersion.…”
