Since new techniques to achieve pressures of below 10/sup -12/ Torr have been developed, gauges with an appropriate low pressure limit are required. Channeltrons, with their high gain, seem to be the best means to construct gauges with high sensitivity. In this paper a new ionisation gauge using a channeltron has been described. (15 refs)
