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 ...

Tenzin Officially Starts His Thesis Work on Ra EDM

Today Tenzin passed his first PhD Committee meeting. His thesis project will be an improved measurement of the EDM of Ra-225. He will be moving to Argonne to work with our collaborators on improving the atom detection efficiency as well as other upgrades. Congratulations!  

Major Renovations to Spinlab Complete

Most of the major renovations to Spinlab are complete! This included adding additional clean power and standard power, cable trays, casework, and a sink & eyewash among many other things. Today we celebrated with a fancy cake with fancy cake decorations. We are now waiting for our optical tables and tunable lasers!

Spinlab Group Pictures

The ground has grown significantly over the last year with the addition of Jennifer Wenzl (postdoc), Dustin Frisbie (grad), Kristen Parzuchowski (DRS Scholar) on the Single Atom Microscope project and Tenzin Rabga (grad), Roy Ready (grad), and Steve Fromm (DRS Scholar) on the Ra EDM experiment.  

Assembly of HV Electrode UHV Chamber

One of responsibilities for the Ra EDM experiment is to test and condition high voltage electrodes. The goal is to achieve an electric field that is at least three times higher than what we’ve achieved in the past. This should improve the statistical sensitivity of our experiment by at least a factor of three and ...

The October Event

Today we celebrated the career of the former NSCL/FRIB Lab Director C. Konrad Gelbke and the release of Sam Austin’s book Up From Nothing which tells the story of the Cyclotron Lab from its humble beginnings in 1958. Aphorisms from CKG: The Big Picture is Important  Communication is the Product Intensity is good – but ...

Spinlab is Under Construction

Spinlab will require tunable single frequency lasers for much of our research. These lasers will have to be installed on stable & vibration-isolated optical tables which are enclosed in a dust-free clean-room style enclosure. These are being designed now, but, while we wait, we are manually removing the dust from above the tiles of the drop ...

Postdoctoral Position Available

The NSCL at MSU is seeking a postdoctoral research associate to utilize a variety of atomic, molecular, & optical physics techniques to search for time reversal violation in nuclei and to optically manipulate nuclei embedded in cryogenic solids. Our group is part of the Radium EDM collaboration, which just performed the first “proof-of-principle” measurement of ...
