Compact, ultra-high vacuum compatible, high power density conductive heaters

Abstract

We present a design and evaluation of a simple and easy-to-fabricate conductive heater intended for ultra-high vacuum experiments. We demonstrate a compact and power-dense heater that has minimal outgassing up to nearly 200 °C. We further detail a method for using the heater in air to heat an object in vacuum by partially replacing a glass vacuum chamber wall with silicon, avoiding some possible outgassing issues. This method has successfully loaded a 2D magneto-optical trap feeding a 3D magneto-optical trap in rubidium 87.
