4985. Continuous flow reflux oven as the source of an effusive molecular Cs beam

R. D. Swenumson, Uzi Even

The design and the operation of a continuous flow reflux (CFR) oven used for the formation of an effusive Cs molecular beam which is compatible with ultrahigh vacuum (10−9 Torr) conditions are described. The CFR oven operation utilizes capillary action to recycle the unused part of the Cs molecular beam. A possibility of extending the principle to supersonic beam pressures is discussed.

We present a simple and inexpensive design for a multichannel effusive oven nozzle which provides improved atomic beam collimation and thus extended oven lifetimes. Using this design, we demonstrate an atomic lithium source suitable for trapped-atom experiments. At a nozzle temperature of 525 °C, the collimated atomic beam flux directly after the nozzle is 1.2 × 10(14) atoms/s with a peak beam intensity greater than 5.0 × 10(16) atoms/s/sr. This suggests an oven lifetime of several decades of continuous operation.
