Microhollow cathode discharge (MHCD) plasmas in high-pressure Ne (up to and exceeding atmospheric pressure) are known to be efficient sources of Ne 2* excimer radiation in the vacuum ultraviolet spectral region between 75 and 90nm. By operating the MHCD plasma in a pulsed direct current (dc) mode, we were able to increase the Ne 2* excimer emission by up to 1 order of magnitude...
