Abstract

The invention discloses a two-dimension adjustable temperature control beam source device and relates to the technology of atomic beam tests. The two-dimension adjustable temperature control beam source device comprises a heating portion (10), a connecting portion (20) and an adjusting portion (30), wherein the heating portion (10), the connecting portion (20) and the adjusting portion (30) are connected vertically in sequence. The heating portion (10) is fixed on a stainless steel support (21) of the connecting portion (20) through bolts and can be conveniently detached and replaced. The adjusting portion (30) makes close contact with a stainless steel supporting column (26) through sliding blocks (32), and the adjusting portion (3) is adjusted through micrometer knobs (31). The two-dimension adjustable temperature control beam source device guarantees the stability of an atomic beam, can achieve precise two-dimensional adjustment of the position of the atomic beam, and is suitable for detecting a signal depends on laser space distribution. The two-dimension adjustable temperature control beam source device respectively obtains signals coming from different laser areas in an action region through fine adjustment of the position of the atomic beam, and thereby the two-dimension adjustable temperature control beam source device can diagnose the quality of laser spots in the action region.

Description

technical field [0001] The invention relates to atomic beam experiment technology, in particular to a two-dimensional adjustable temperature control beam source device. Background technique [0002] In many experimental studies involving laser cooling of atoms, atom-particle collisions, and atom-laser interactions, etc., obtaining a stable and high-density atomic beam source in the active region is an indispensable prerequisite. Because many research objects (such as metal atoms) are solid at room temperature, people usually use high temperature to vaporize the sample to a gaseous state. Under the action of saturated vapor pressure, atoms are ejected from the small hole above the sample cell to the active area to form an atomic beam. A general atomic beam source device is mainly composed of a heating device, a temperature control system and a crucible (sample pool). Due to the different melting points and saturated vapor pressures of different samples, and the deformation o...
