ABSTRACT:
A sensor having a light detector with a small gap between the cathode and anode to enable a high pressure cavity resulting in a long lifetime of the detector due to insignificant sputtering from the cathode and subsequent minimal burying of the noble gas in the cavity. The detector may be made with MEMS technology and its techniques. The sensor may contain an array of light detectors. Some of the detectors may be UV detectors.
