Abstract
A new calibration method for slotted disk velocity selectors is presented and is compared with other calibration procedures. It is based on the measurement of the velocity distribution of a supersonic molecular beam produced by a room temperature source. The error due to the assumed theoretical distribution and to experimental procedure is discussed. It is shown that the velocity scale is known to within 0.8%.Keywords
