Beschreibung
Zusammenfassung:	An electronic sampling head comprising a housing having a path for impinging radiation, a photoemissive element positioned across said path, photoelectron ejection means positioned in proximity to said photoemissive element, means for applying ultrashort sampling potential differences between said photoemissive element and said photoelectron ejection means for accelerating photoelectrons emitted by said photoemissive element in response to said incident radiation, and means for detecting said photoelectrons all resulting in the capability of detecting high-speed radiation phenomena with waveform fidelity.
