摘要

A source of radiation pulses composed of: a cylinder 10 defining a sealed cylinder chamber and provided at one end with a radiation permeable window 15; a mass of gas 14 disposed in the cylinder chamber, the composition of the gas being such as to be adiabatically heated and excited to emit radiation in a rotation-vibration spectrum upon being compressed; and a piston 11 disposed in the chamber to be freely movable in the direction of the longitudinal axis 12 of the cylinder 10 for periodically compressing the gas. Preferably, the piston 11 is driven by magnetic forces acting in the direction of the longitudinal axis 12 of the cylinder.
