About the Group

The ESCA Users group is a forum for scientists from academia and industry with a common interest in Electron Spectroscopy for Chemical Analysis and surface science in general. It meets twice yearly, in January and July, to discuss the latest research and issues of interest to the surface science community and to exchange views on current trends. In addition to these regular meetings the group produces a newsletter for its members which is available on-line from this site. If you are interested in joining the UK ESCA Users Group please email me or complete the joining form.

Surface Science and the Millenium bug Y2K: Will my Spectrometer work in January? The following is a list of links to various manufacturers and agencies with information on the Y2K problem. Some of the links will enable you to establish whether your instrumentation is going to work in 2000. The remainder are of a more general nature, but may be of use if you are not sure what you have to do to be "compliant". bar

Definition of Y2K Compliance "Compliance" is generally defined in the same way as the British Standards Institution's (BSI) DISC PD-2000-1 "A Definition of Year 2000 Conformity Requirements". In brief this requires that:

Neither performance nor functionality is affected by dates prior to, during and after the year 2000. No value for the current date will cause any undesired interruption of operation during a product's expected lifecycle. Date-based functionality behaves consistently for dates prior to, during and after year 2000. In all interfaces and data storage, the century in any date is specified either explicitly or by unambiguous algorithms or inference rules. Year 2000 is recognized as a leap year ( '00 years are only leap years when the year is divisible by 400)

A y2k testing schedule and checklist for y2k compliance can be downloaded from here.
