Production of a slit skimmer for use in cold supersonic molecular beams

Rev Sci Instrum. 2008 Jan;79(1):016101. doi: 10.1063/1.2814026.


Cold molecular beams generated by skimming pulsed supersonic gas expansions normally employ conical skimmers. The use of slit shaped skimmers instead of conical skimmers can afford significant signal enhancements. At this time, however, slit shaped skimmers are not available commercially. We describe a straightforward method for producing functional slit skimmers.
