摘要
An electrostatic quadrupole is used to filter slow dipolar ND3 molecules from an effusive source and to guide them into ultrahigh vacuum. The molecules in the electrostatic quadrupole experience a Stark interaction which allows filtering of small velocities in the linear and bent sections of the quadrupole. With this technique we demonstrate a flux of approximate to10(10)/s with a longitudinal temperature of a few K. The technique and the set-up are discussed in detail, and the guided gas as well as the output beam are characterized. Improvements in the set-up are highlighted; as for instance cooling of the effusive source to below 150 K.
