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 ...

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), real time (can be performed ...

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. ...

Claude Shannon’s 1952 Lecture on Creative Thinking

A lecture by Claude Shannon on Creative Thinking is buried deep inside of his Miscellaneous Writings edited by N. J. A. Sloane & Aaron D. Wyner in 1990. It has been rediscovered in some sense by the authors Jimmy Soni & Rob Goodman who have just recently published a biography of Shannon. One of the ...
