Calibration of a Slotted Disk Velocity Selector Using Supersonic Molecular Beams
ثبت نشده
چکیده
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%.

The cooling of molecules during the adiabatic expansion of supersonic seeded molecular beams is reviewed and illustrated by the example of NO -molecules. The reduction of the Doppler width by collimation of the beam and the cooling to low rotational temperatures brings a significant simplification of the complex NO -absorption spectrum and allows its assignment. The measured rotational tem...
متن کاملSupersonic beams at high particle densities: model description beyond the ideal gas approximation.
Supersonic molecular beams constitute a very powerful technique in modern chemical physics. They offer several unique features such as a directed, collision-free flow of particles, very high luminosity, and an unsurpassed strong adiabatic cooling during the jet expansion. While it is generally recognized that their maximum flow velocity depends on the molecular weight and the temperature of the...

متن کاملPrecision velocity measurements of pulsed supersonic jets.
We introduce a straightforward experimental approach for determining the mean flow velocity of a supersonic jet with very high precision. While time measurements easily can achieve accuracies of Δt/t ≤ 10(-4), typically the absolute flight distances are much less well-defined. This causes significantly increased errors in calculations of the mean flow velocity and mean kinetic energy. The basic...
