Apparatus for detecting a photon pulse
First Claim
1. Apparatus for detecting a photon pulse as a function of time, comprising a pulse converter for converting a photon pulse to be detected into an electron stream, first deflection means for deflecting the electron stream as a function of time and a position-sensitive detector for determining the deflection of the electron stream, characterized in that the pulse converter comprises a gaseous medium in order to absorb the photon pulse for detecting and to emit the electron stream.

Abstract
Streak camera whereof the pulse converter for converting a photon pulse for detecting into an electron stream comprises a gaseous medium. A streak camera for a photon pulse in the far-infrared region is provided with a laser source to bring particles in the medium into a Rydberg state, in a streak camera for an X-ray pulse the medium contains particles for bringing into an Auger state, and additional deflection plates are provided for separating a primary electron stream from a secondary electron stream.
