Dark Sectors 2016 Workshop: Community Report
Jim Alexander, Marco Battaglieri, Bertrand Echenard +201
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the…
The Heavy Photon Search Test Detector
Marco Battaglieri, Sergey Boyarinov, Stephen Bueltmann +61
The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing for installation at the Thomas Jefferson National…
Observation of the Askaryan Effect: Coherent Microwave Cherenkov Emission from Charge Asymmetry in High Energy Particle Cascades
David Saltzberg, Peter Gorham, Dieter Walz +6
We present the first direct experimental evidence for the charge excess in high energy particle showers predicted nearly 40 years ago by Askaryan. We directed bremsstrahlung photon…
A Monitor of the Focusing Strength of Plasma Lenses Using MeV Synchrotron Radiation
Clive Field, Gholam Mazaheri, Johnny S. T. Ng
The focusing strength of plasma lenses used with high energy electron or positron beams can give rise to synchrotron radiation with critical energies in the MeV range. A method is…
