Direct, absolute, and in situ measurement of fast electron transport via Cherenkov emission.
We present direct measurements of the absolute energy distribution of relativistic electrons generated in intense, femtosecond laser interaction with a solid. Cherenkov emission radiated by these electrons in a novel prism target is spectrally dispersed to obtain yield and energy distribution of electrons simultaneously. A crucial advance is the observation of high density electron current as p...
متن کاملTagging single muons and other long-flying relativistic charged particles by ultra-fast timing in air Cherenkov telescopes
Atmospheric air Cherenkov telescopes are successfully used for ground-based, very high-energy (VHE) γ ray astronomy. Triggers from the so-called single muon and other long-flying relativistic charged particle events are an unwanted background for the Cherenkov telescope. Because of low rate at ∼ TeV energies the muon background is unimportant. It is much more intense for telescopes with high ph...
متن کاملResponse of the Pierre Auger Observatory Water Cherenkov Detectors to Muons
Two test detectors similar to the Pierre Auger Observatory Water Cherenkov Detectors have been installed at the Observatory site and at the Institut de Physique Nucléaire d’Orsay. The signals from the tanks are read out using three 9” photomultipliers and analyzed by both a digital oscilloscope with high sampling frequency and the Auger surface detector electronics. Additionally, the detectors ...
متن کاملTwo-dimensional Cherenkov emission array for studies of relativistic electron dynamics in a laser plasma
In laser-produced plasmas there are several effects which will scatter a longitudinally probing relativistic electron beam. In vacuum, the laser itself will ponderomotively defocus the electron beam, while in plasma the ponderomotive force can dig an ion channel which would focus the electron beam. In the cases of plasma wave excitation via the beat-wave or wake-field mechanisms, the thermaliza...
