Steve Wins Broad of Trustees’ Scholarship Award!

The Weekly Win goes to Director’s Research Scholar Steve Fromm, who was awarded a Board of Trustees Scholarship Award! This award is given to only ~50 out of ~10,000 graduating seniors (top 0.5%!) every year who have “the highest cumulative grade-points at the close of semester prior to graduation.” Furthermore, “To be eligible for these ...

Roy Ready receives a DOE SCGSR Award!

Roy Ready has been selected to receive the U.S. Department of Energy (DOE) Office of Science Graduate Student Research (SCGSR) award for the proposed research project, “Towards a More Sensitive Measurement of the Electric Dipole Moment of Radium-225”, to be conducted at Argonne National Laboratory (ANL) with our collaborator Matt Dietrich. Roy was selected is ...

Six Undergrads Receive Support to Participate in CEU-DNP 2017

Six students were selected to participate in CEU-DNP this October in Pittsburgh and were offered support for lodging for their participation: Courtney Nelson (REU Student): Optical Thin Film Thickness Measurement for the Single Atom Microscope Daniel Coulter: Design of a Prototype Single Atom Microscope for Nuclear Astrophysics Evan Ryan (Honors College Seminar): Characterizing Optical Backgrounds ...

Summer LODY!

This summer has been a very productive summer for the Spinlab group, but to get all that work done we had to get down and dirty. So much excellent work was being done that the lab became a war zone of tools, equipment, and circuit diagrams. Organizing it would prove to be a herculean task ...

The Great Bipolar High Voltage Power Supply Installation of 2017

What is a bipolar power supply and why do we need it? In the Ra EDM experiment, a high electric field flips sign on a roughly 1-minute cycle. The direction of the field is changed by reversing the sign, or polarity, of the voltage being applied across the “hot” cathode (field is defined by positive-to-negative charge direction). ...

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 gas handling system (GHS) which ...

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 sources, this is not true. ...

Kristen’s Guide to Success in Spinlab

Spinlab group alumna Kristen Parzuchowski (MSU ’17, now 1st year graduate student at UC-Boulder now) has written an informal “guide to success in Spinlab.” This document has started to take on a life of its own and has been requested several times since she passed it along to the group. She has kindly given me ...

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 during a real permanent EDM experiment. ...

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 run two years ago. Before ...
