Abstract

Substantial error in estimating widths of supersonic molecular beam speed distributions can result when using a conventional quadrupole mass spectrometer in pulse-counting mode as a molecular beam detector. This results mainly from improper discriminator settings reached in attempting to maximize signal to background. The effect is illustrated with measurements on a nominally Mach-10 helium supersonic beam.
