Atomic beam sources for ultracold transition-metal atom experiments
Abstract
Atomic beam sources for ultracold transition-metal atom experimentsResponse to Program Announcement ONR: N00014-21-S-F002Program man,ager: Dr. Roberto DienerIt has recently been shown that nearly a dozen transition-metal atoms have the requisite atomic structure to, allow laser cooling to ultralow temperatures. Such laser cooling is a precursor to novel applications of these atoms to sensing, ti,me-keeping, studies of quantum science, and probes of fundamental physics. However, the standard methods for producing atomic beams, in current laser cooling experiments are not applicable to these transition metals, many of them refractory metals with very high m,elting and sublimation temperatures. This DURIP project supports the construction andtesting of two types of atomic beam sources tha,t are universally applicable to transition metals and compatible with the experimental techniques of laser cooling, magneto-optical, trapping, and ultrahigh vacuum. Specifically, this project supports the acquisition and testing of rod-fed electron- bombardment so,urces, which produce high velocity atomic beams with little extra gas load into an ultrahigh vacuum chamber system, and also of a cr,yogenic buffer gas beam source, which produces lower velocity beams while also requiring greater management of the gas load of the b,uffer gas. Each source will be tested, with the atomic beams analyzed by optical spectroscopy using equipment included in this DURIP, request. Success in this project will open a path for an enormous range of scientific studies using a new family of ultracold atomi,c gases.This abstract is intended for public release.Submitted for consideration to:AFOSR: Dr. Boyan Tabakov, Program Officer, Atomi,c and Molecular Physics, Email: boyan.tabakov@us.af.milONR: Dr. Roberto Diener, Program Officer, Department: Code 312, Email: robert,o.diener@navy.mil ARO: Dr. Paul Baker, Program Manager, Atomic and Molecular Physics, Email:paul.m.baker4.civ@mail.mil
