Milne, J.; Hammond, A. D.

The basic principles of mass spectrometer helium leak testing of large pressure vessels using polythene sheet as a secondary containment have been investigated and experimental results obtained. Techniques of (a) calibrating helium leaks, (b) measuring the helium diffusion rates through pinholes and (c) measuring permeabilities to helium of polythene are described.
