The following

The Vacuum Group of the Institute of Physics and the E5 Professional Group of the Institution of Electrical Engineers are to hold a joint conference on ‘Vacuum Devices’ at the New Cavendish Laboratory, Cambridge from 24 to 28 March 1980. The conference will embrace the electronic design and performance of devices, and also manufacturing problems with special emphasis on the vacuum environment. Such subjects as designs for improved characteristics, novel devices, construction and processing techniques, gettering, electron emission and diagnostic and measuring techniques would come within the scope of the conference.

The Atomic Collisions in Solids Group of the Institute of Physics is holding a conference on Low Energy Ion Beams from 14-l 7 April 1980 at the University of Bath. It will provide an opportunity for scientists of many disciplines working with ion beam and plasma-based systems (operating typically between about 1 keV and 1 MeV) to get together. The conference aims to promote a good exchange between specialists in ion source development and beam production on one side and applications-oriented researchers and technologists on the other. In this rapidly developing field, ion beams and plasma deposition processes are being deployed for damage studies, fusion research, semiconductor processing and machining, materials modification in metals and insulators and surface scattering analysis. The common thread to

these important technological areas is the production and manipulation of beams and plasmas of varying properties and quality depending on their end use. The conference will not include fundamental atomic collision scattering at electronvolt energies for example, or papers on Rutherford backscattering and nuclear reaction analysis except where these topics are directly relevant to beam manipulation or materials modification studies. Papers are invited in the following areas : Recent developments in ion source technology ; Excitation, ionization and charge transfer; Ion optics and beam transport; High current ion sources and neutral injection ; Recent developments in heavy ion accelerators ; Beam detection and measurement; Low energy ion beam systems for surface studies; Physical and chemical effects on ion bombarded surfaces, including deposition and etching.

companies will be taking part and presenting a display which is being designed as a ‘shop window’ of the products and services that will be needed by both the public and private hospital and health-care sectors during the next decade. The promotion campaign to attract laboratory equipment buyers to the show is being mounted against the background of increasing pressure to reduce the cost of running hospitals in all sectors, not only in Britain but also in many other European countries, while maintaining or increasing standards. In 1980, in Britain alone, some f700 million will be spent on the National Health Service of which a substantial proportion will be used for the purchase of equipment, materials, supplies and services essential for the up-keep and efficient day-to-day running of the country’s hospitals. The 1980 British Hospitals and Medical Exhibition, as in previous years, is being sponsored by the Institute of Health Service Administrators and supported by the DHSS and all the main professional and employee organizations in the field. Because of the exhibition’s premier size and scope and the reputation of Britain’s hospital and medical equipment and supplies manufacturers, the show will be attended by a large number of foreign buyers from Europe, the Commonwealth, Africa, the Indian Sub-Continent, the Middle East and Far East and other parts of the world.
