The liquid krypton calorimeter for experiment CERN-NA48

A quasi-homogeneous liquid krypton electromagnetic calorimeter is under construction for a precision study of CP violation in neutral kaons decays. The main characteristics of the detector are discussed, together with results on energy, space and time resolution obtained with a prototype detector.

Particles for tracing turbulent liquid helium

We address the problem of making quantitative measurements of local flow velocities in turbulent liquid helium, using tracer particles. We survey and evaluate presently available particles and previous work to establish the need to develop new particles for the purpose. We present the first practical solution for visualizing fluid motions using a suspension of solid hydrogen particles with diam...

The Scattering of Light from Liquid Helium

A review is given of the scattering of light by superfluid helium. A brief discussion is given first of the theory of Brillouin and Rayleigh scattering from an ordinary simple pure liquid. It is shown how this discussion must be modified in the case of the superfluid phase of purc 4He, and experimental observations of Brillouin scattering from first sound in liquid helium are described. The dis...
