Recirculating atomic beam oven

Gary M. Carter, David E. Pritchard

Published Jan 1, 1978• 8 citations
Publisher

Abstract

We describe an atomic beam oven that reuses alkali metal in the unused portion of the beam. This is accomplished by condensing the desired vapor on a cooled jacket from which it may be drained back into the oven.

Design of a three-stage alkali beam source

Melissa Lambropoulos, Stephen E. Moody

A three-stage effusive alkali beam source is described in detail. Among the advantages of this device over ordinary effusive ovens are greatly increased intervals between refillings, and the production of beams with significantly reduced alkali dimer densities.

Low-consumption atomic beam source

G.J. Witteveen

A sodium atom beam source is described in which those atoms which intercept the collimator surface are returned to the oven chamber, thus minimizing the total sodium consumption for a given collimated beam intensity.

Designing an Atomic Beam

Cyril Bernard Lucas

Generally lower temperatures of evaporation make most aspects of oven design easier than those discussed in Chapter 5 and included in this group are ovens for the production of beams of alkali metals and their salts. Some special techniques are, however, necessary to handle the alkali metals because of their reactivity with moist air, which increases with atomic number Z. One solution is to produce the beam by a reaction of stable substances in the oven and we begin the discussion of the alkali metals with those cases in Section 4.2. We then consider in Section 4.3 more conventional ovens where the material to be evaporated is loaded directly into the oven. In Section 4.4 we turn to the alkali halides, which have problems due to their corrosiveness in the liquid and vapour state. Ovens where an ampoule of material has to be broken are discussed in Section 4.5. Finally in this chapter we discuss recycling ovens, where material that is not formed into a useful beam is returned to the oven.

A simple atomic beam oven with a metal thermal break

Chetan Vishwakarma, Jay Mangaonkar, Kushal Patel +3 more

We report the design and construction of a simple, easy to machine high temperature oven for generating an atomic beam in laser cooling experiments. This design eliminates the problem of thermal isolation of the oven region from the rest of the vacuum system without using a glass or ceramic thermal break. This design simplifies the construction and operation of high temperature ovens for elements having low vapor pressure. We demonstrate the functionality of such a source for strontium (Sr) atoms. We generate a high flux of Sr atoms for use in laser cooling and trapping experiments. The optimization of the design of the metal thermal break is done using a finite element analysis.
