TL;DR
This paper presents a novel atomic oven design for ion traps that enables rapid control of atomic flux, achieving a 12-second response time for calcium atoms, with potential for even faster operation through heat treatment.
Contribution
The authors introduce a fast-response atomic oven optimized for ion trap experiments, demonstrating reproducible construction and reduced response times compared to traditional sources.
Findings
Achieved 12s flux response time for $^{40}$Ca atoms.
No flux overshoot during operation.
Potential for faster response with heat treatment.
Abstract
Ion traps are often loaded from atomic beams produced by resistively heated ovens. We demonstrate an atomic oven which has been designed for fast control of the atomic flux density and reproducible construction. We study the limiting time constants of the system and, in tests with , show we can reach the desired level of flux in 12s, with no overshoot. Our results indicate that it may be possible to achieve an even faster response by applying an appropriate one-off heat treatment to the oven before it is used.
