A very low-energy positron spectrometer for scattering measurements in gases is presented. The apparatus uses electrostatic optics, two stages of positron moderation, magnetic focusing in the scattering chamber and a pseudorandom time-of-flight correlation technique.

Abstract
A very low-energy positron spectrometer for scattering measurements in gases is presented. The apparatus uses electrostatic optics, two stages of positron moderation, magnetic focusing in the scattering chamber and a pseudorandom time-of-flight correlation technique.File in questo prodotto:
