摘要：

The intensity is obtained from the work done on a cylindrical rotating body by the torque exerted by the impinging beam particles. The detector takes advantage of the very low and constant bearing friction of magnetically suspended rotors and of the complete particle momentum accommodation on uncleaned surfaces. The molecular-beam detector turns out to be an absolute instrument. Principle, experimental performance, and measurements with helium nozzle beams are reported.
