Abstract
A micro secondary electron multiplier or an array thereof employs discrete dynodes which are microstructured and applied to an insulating substrate plate. The substrate plate is provided with electrical conductor paths for the connection of the dynodes. The dynodes can be made using a technique such as X-ray depth lithography-galvanoplasty (the LIGA technique). The micro secondary electron multiplier or an array of such multipliers is extremely small and sensitive, and has a high time resolution. Furthermore there is considerable flexibility in positioning the multipliers of an array.
