文摘
Development of a hot cathode ionisation gauges for neutral gas density measurement using alternatively the alternating current as source for heating power. The benefit of such a technique is besides saving of heating power, especially space-saving by applying thinner power supply cables. Different filament deigns are presented. A numerical analyses is presented, begin with a transient thermal followed by an electromagnetic and finally a structural dynamic analysis. The aim of the analysis of the filament heated by AC is to find out the frequency of the heater current for a proposed design (jxB)(jxB).
