DOE Awards Spinlab Early Career Research Funding
Towards a Next Generation Search for Time-Reversal Violation Using Optically Addressable Nuclei in Cryogenic Solids Certain rare pear-shaped nuclei have unmatched sensitivity to new kinds of forces between subatomic particles that are not the same when the arrow of time is reversed. Such forces are believed to be responsible for the near absence of antimatter ...
First Neon Film in prototype Single Atom Microscope
The prototype Single Atom Microscope has been assembled and has passed two critical test. The substrate upon which we grow the solid neon thin films can be cooled to around 7 K which is cold enough to grow neon films. We have grown neon films at a rate of roughly 1 micron per ...
Adam, Brian, Fry, and Steve Graduate!
Congratulations to Adam, Brian, Fry, and Steve! They are all graduating this semester and participated in the graduation ceremony on December 16, 2017 in Breslin Center. Adam Powers joined the group in April 2016 and has contributed to all aspects of the high voltage electrode development for the Ra EDM experiment including residual magnetization measurements ...
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. ...
