Smith–Purcell Radiation from Low-Energy Electrons

Radiation from polarized electrons in oriented crystals at high energy

Radiation from high energy electrons in an oriented crystal can be considered in a frame of the quasiclassical operator method which appears to be a most satisfactory approach to the problem. Under some quite generic assumptions the general expression is derived for the probability of circularly polarized photon emission from the longitudinally polarized electron in oriented crystal. The partic...

Collisions of low-energy electrons with isopropanol

We report measured and calculated cross sections for elastic scattering of low-energy electrons by isopropanol (propan-2-ol). The experimental data were obtained using the relative flow technique with helium as the standard gas and a thin aperture as the collimating target gas source, which permits use of this method without the restrictions imposed by the relative flow pressure conditions on h...

A tracking detector for low energy electrons

Amultiwire proportional chamber has been developed to study the properties of a detector for tracking of low energy electrons (0.2–1 MeV). The geometry and the materials used have been optimized to minimize energy losses and multiple Coulomb scattering. The detector is equipped with a special electronic readout and event selection system, consisting of an amplifier=comparator stage, a fast trig...

Can Low-Energy Electrons Affect High-Energy Physics Accelerators?

014801-1 Present and future accelerators’ performances may be limited by the electron cloud (EC) effect. The EC formation and evolution are determined by the wall-surface properties of the accelerator vacuum chamber. We present measurements of the total secondary electron yield (SEY) and the related energy distribution curves of the secondary electrons as a function of incident-electron energy....
