Photomultipliers offer high gain, low noise and fast time response. They are among, if not the most popular and widely used detectors for spectroscopy. It makes sense then, to detect vacuum ultraviolet radiation with a photomultiplier tube. But photomultiplier tubes cannot detect very short wavelengths by themselves. Their glass or quartz enclosure limits the response range. Addition of a ...
