Colloquium @ Central Michigan University

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 CP-violation may be needed to ...

Radio Shack

The Spinlab’s unique inventory of world-class equipment and facilities paired with it’s innovative team members allows for the execution of intricate and critical experiments. Improvements, additions, and customizations are constantly being made around the lab. An example of this is the weekly win awarded on 10/17/16 to Roy Ready for his work in building a ...

E-Field of 110 kV/cm

This weekly win post is for the win awarded on 10/10/16. The win that week was awarded to Roy Ready’s team, working on the Ra EDM project. The RaEDM team  successfully tested the high voltage system, and reached a stable operating voltage of 22 kV. One of the goals  of the project is to reach the ...

Fluorescence Yield of Yb Inside Solid Ne

The win this week belongs to the SADiCS team, who have been working to detect single atoms in solid noble gases in order to measure rare nuclear reactions in an energy range best suited for astrophysics (more information can be found here). This week the SADiCS team consisting of Dustin Frisbie, Kristen Parzuchowski and Jennifer Wenzl ...

Residual Magnetization Gradiometer

As of this week, there will be a weekly blog post titled “Weekly Win”. Each post will include information and a short blurb about something significantly exciting or remarkable which occurred in the lab that week, and each week the members of this group will vote for one of various nominations in order to determine ...

Colloquium @ University of Nevada-Reno

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.

First Steps Towards Two-Photon Magnetometry Using Polarized Noble Gases

We are collaborating with Skyler Degenkolb and Prof. Tim Chupp from the University of Michigan on demonstrating two-photon magnetometry using nuclear-spin polarized noble gases. Spinlab happens to have an intense and tumble UV laser source needed for this project. The first step is to find the UV two-photon transition in gaseous Xe. Shown below are ...

Debugging An Obscure Non-Fatal Failure Mode for a TMP 50 Turbopump

While testing the new TMP 50 (S/N31001349549) on the HV setup, it failed three times. All three times, the TMP was started at a pressure of 4E-3 Torr or below and failed about 4 minutes into the acceleration at pressures of 6E-5 Torr or below. Before the last attempt, we ran the roughing pump with the gas ballast valve ...

The Great Laser Installation of 2016

The Spinlab tunable lasers from M-squared were installed this week. The GRUVY laser provides tunable single frequency laser light from 250-300 nm, 500-600 nm, and 700-1000 nm. The BLUREI laser provides tunable single frequency laser light from 350-500 nm and 700-1000 nm. Thanks Steven and Daniel!

The Great Laser Table Installation of 2016

Spinlab has two nonmagnetic optical tables fabricated from 304 and 316 stainless steel from TMC. They were installed on the morning of April 23, 2016. These tables provide a very stable and vibration-isolated platform for mounting lasers and performing atomic physics experiments. See how the 12 ft by 4 ft 3000 lb optical table was ...
