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.…

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…

The Great Fry Test of 2017
Optics vendors such as Thorlabs and Newport have figured out that graduate students fed with snacks spend more time aligning lasers than hangry (hungry+angry) students, which has the added benefit of them needing more optics and/or snacks. As a consequence, these companies send out a boxes of snacks with every…

The Chunk Code: HV Stability During an EDM Simulation
This Weekly Win is a celebration of my high voltage ramp test analysis suite, AKA Chunk Code. Let me break this down into ‘chunks,’ if you will: Here is a plot of a high voltage ramp test the Spinlab RaEDM crew performed on 7-5-2017. The ramp test simulates the conditions that the electrodes will be subjected to…

Stable & Repeatable Ramping of 170 kV/cm Electric Field
This week we hit a milestone by successfully running a ramping simulation to 170 kV/cm for ~ 1 hr. This is approximately 15% higher than the goal we set out to reach and more than double the electric field that we were able to achieve during the Ra EDM data…

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…

Magnetic Field Map of Spinlab
This week I completed the Spinlab Magnetic Field Mapping Report, a 31-page LaTeX document outlining the motivation for mapping the magnetic field of the Spinlab, the process for building the components necessary for completing the mapping, and results from various mappings from 2016. This document will be very important for completing any…

Conditioning of HV Electrodes
This week we successfully approached the point of electrode conditioning with our high voltage system. In previous attempts, we were forced to stop short of reaching a high enough voltage due to cable failure–22 kV was the highest we could get. On Tuesday, we were able to reach 27.9 kV…

Measuring the Yb Atomic Beam Flux
On Monday, December 5th the SADiCS team led by Kristen Parzuchowski performed an improved Yb flux measurement. Several improvements were implemented including covering the measurement chamber with a non-reflective black foil to reduce stray light and conducting a more precise scan over wavelengths to find the resonance wavelength of…
