First Neon Film in prototype Single Atom Microscope
The prototype Single Atom Microscope has been assembled and has passed two critical test. It has been reassuring to pass these two tests because we made several design choices to optimize the optical access in order to the maximize the light collection efficiency from individual emitters embedded in the solid neon.…

Producing Scientific Diagrams Which Reveal the Relevant Scale @EdwardTufte
Learning how to produce informative and detailed graphical representations of the equipment used for experiments is a critical skill that takes practice and requires detailed knowledge of what is truly important about each component of the apparatus. For the Single Atom Microscope (SAM) project, we designed and assembled a prototype…

Farewell Andy & Courtney! (2017 MSU REU Poster Session)
Andy and Courtney have completed their REUs with the group this summer and presented their results at the REU poster session. Andy developed a machine vision system for characterizing the HV electrodes used for the Ra EDM experiment. This optical method is high resolution (10 microns), high precision (repeatable),…

Calibrated Spatial Profile Measurements of Extended Light Sources
The purpose of SAM is to image individual atoms that fluoresce upon excitation with a light source that we choose based upon the properties of those atoms. In the past, we’ve made the simplifying assumption that the spatial profile of a light source is uniform, but, for real extended light…

Laser Scanning of Yb Atomic Beam Fluorescence
The Single Atom Microscope team, led by Kristen and Roy, is taking large steps towards a proper calibration of Yb atom number density in solid Neon. Most recently, the atomic beam fluorescence measurements have incorporated laser frequency scanning. At a stable atomic oven temperature, these measurements are used to determine…

Bake of the Ne Gas Handling System
This week, we completed a setup for a vacuum bake. Vacuum bakes are used to remove tiny impurities (specifically water) from a vacuum system. This is done by heating the vacuum components, which makes any water bound to the walls of the stainless steel detach at a faster rate. In this process we use…
