Vacuum ultraviolet coherent undulator radiation from attosecond electron bunches

Abstract Attosecond duration relativistic electron bunches travelling through an undulator can generate brilliant coherent radiation in the visible to vacuum ultraviolet spectral range. We present comprehensive numerical simulations to study the properties of coherent emission for a wide range of el...
