This technical note by Lee & Yang, first published in October 1957, is based on a series of lectures given in January 1957. Of particular note is “Section III.4 Static Electric Dipole Moment” on page 17 which indicated, perhaps for the first time, that non-zero EDMs would violate not only…

2017 University Undergraduate Research and Arts Forum
Six Spinlab undergraduate researchers will be presenting on our research on April 7 as a part of MSU’s 2017 University Undergraduate Research and Arts Forum. Abstracts (links), titles, and locations for the posters (2) and talks (5) are below. Name: Kate Nezich Title: How to Make Atoms Glow: Characterization of Different LED’S for the Detection…

Laser Trap Monte Carlo Simulation
We have upgraded the Laser Trapping Monte Carlo to include a laser chirping feature. This new feature allows for the addition of a linear frequency chirp to be added to any of the lasers in the simulation. This is one of the first needed steps in being able to simulate…

Seminar @ Bucknell
Testing Time-Reversal Symmetry Using Lasers, a Magic Room, and Pear-Shaped Nuclei Experimental tests of fundamental symmetries using nuclei and other particles subject to the strong nuclear force have led to the discovery of parity (P) violation and the discovery of charge-parity (CP) violation. It is believed that additional sources of…

HVPlotter in Python
Over the last week, I have developed a program in Python for quickly plotting data made from the exported data from the jhv4 labview program. The program has the user select which file they want to make plots from, and then opens the attached window. The user will then select…

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…

CUSTIPEN-IMP-PKU Workshop on Physics of Exotic Nuclei
I was asked to give a talk on “The Search for Electric Dipole Moments Using Octupole-Deformed Nuclei” @ the Workshop on Physics of Exotic Nuclei in Huizhou, Guandong, China. This is the first public talk I’ve given on our concept for a Protactinium-229 EDM search in the FRIB era. While in China,…

Safety Interlock for HV Supply
This week is all about our electrode test station. We’ve made significant safety improvements and improvements in the sensitivity of our high voltage measurements. The first is the installation of our fancy new Interlock Chassis, which allows us to remotely shut down the power supply. It also automatically cuts power to the high voltage power supply…

Python Code to Control Four Relays
The “Weekly Win” for the week of Nov. 7th was awarded to Liam Clink for completing the code which will be used for the degaussing project in the RaEDM study. “This past week I finished getting the code for the degaussing project functional. This code will be used in a Raspberry…

APS DNP Vancouver 2016
Four members of the Spinlab team made the trip to Vancouver for the annual fall meeting of the Division of Nuclear Physics of the American Physical Association held Oct. 13-16th. The team contributed talks and posters regarding their work at the MSU Spinlab and was composed of Jaideep Singh, Roy…
