Hazard control for helium-neon gas lasers
The British Journal of Radiology, 1970In many cases health physicists are now concerned with protection arrangements for laser installations. The Institute has indicated that its interests extend to nonionising radiations, and so, from previous experience, may be able to provide some professional support in the preparation and implementation of generally acceptable protection ...

The optimal helium fraction for air–helium gas mixture HDDs
Microsystem Technologies, 2015Helium-filled drives have recently been commercialized to enable a high recording density. However, because the use of helium increases production costs, binary gas mixtures such as air---helium have been investigated. In this paper, the dominant performance metrics of hard disk drives (HDDs) are the windage losses, the flow induced vibration (FIV ...
