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....

Observations of Terrestrial Gamma-Ray Flash Electrons

Terrestrial gamma-ray flash (TGF) emissions are predicted to be accompanied by energetic electron emissions. These electrons have been suggested to explain several anomalous TGF observations by the RHESSI and BATSE spacecraft. These electrons additionally provide a new window for study of TGFs as they carry additional information about the source through their pitch angle / arrival time distrib...

High-energy drinks may provoke aortic dissection.

High-energy drinks have become extremely popular after Red Bull's promotion at 1987 in Austria and 1997 in the United States. Since then, we witnessed spectacular increase in different brands, caffeine content and market consumption all over the world. However, there are no reports published in the scientific literature related with detrimental side effects after heavy consumption of high-energ...

Imaging high-energy electrons propagating in a crystal.

It has recently become possible to focus a beam of high-energy electrons to a spot smaller than an atom, with vast potential for the study of condensed matter. We devise an experiment that can image, with subangstrom resolution, the distribution of such an electron beam as it scatters within an atomic lattice. Our experiments reveal the acute sensitivity of the scattered electron distribution t...
