Laser beams as fiducial lines in bubble chambers

It is proposed to base the fiduciary system of large volume bubble chambers on laser beams originating from theodolite-fixed positions and thus traversing the liquid at well defined space coordinates. From a series of experiments some important conditions for this proposal have been established: Ray...

description It is proposed to base the fiduciary system of large volume bubble chambers on laser beams originating from theodolite-fixed positions and thus traversing the liquid at well defined space coordinates. From a series of experiments some important conditions for this proposal have been established: Rayleigh-scattering on molecular concentration fluctuations in the chamber liquid is responsible for the visibility of laser beams which can be photographed under angles up to 90 degrees within reasonable exposures. Small-angle random deflections of the laser beam were observed which are due to thermal turbulence in the chamber liquid.
