Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Long term stable cold cathode with reliable ignition</bold> </p> <p>Cold cathodes gauges have been used in various areas of vacuum technology for decades. Their unique properties make them the method of choice even despite the residual magnetic field, poor ignition characteristics in the UHV‐region and long term stability. In other applications they do not significantly shorten the maintenance intervals. However, especially in the UHV or XHV region these properties lead to an extinguishing of cold cathode discharge.</p> <p>Considering the underlying processes and their correlation in this contribution an improved cold cathode will be presented. The measured data show a residual magnetic field of 1 mT in close vicinity to the gauge and an extended operating pressure range down to the 10⁻¹² mbar region. Furthermore the ignition characteristics were improved to &lt; 60 s at 1×10⁻⁹ mbar.</p> </abstract>
