Surprise, Surprise!

We use several compressed gas bottles in Spinlab. Each of these bottles is secured to a wall when in use and transported on a tiltable cart with four wheels. Of course, when the bottles are being transported, we make sure that the gas bottle cap is securely screwed onto the top, because we don’t want ...

Magnetic Field Map of Spinlab

This week I completed the Spinlab Magnetic Field Mapping Report, a 31-page LaTeX document outlining the motivation for mapping the magnetic field of the Spinlab, the process for building the components necessary for completing the mapping, and results from various mappings from 2016. This document will be very important for completing any future B-field mappings, especially once I ...

Righty Tighty, Lefty Loosey

The lab was confronted with a stuck knob on one of our Helium gas regulators. Many of the other lab members attempted to open the outlet valve to the regulator but that proved unsuccessful. I attempted to open the stuck valve as well, even using the strap wrench as shown. I had the thought that ...

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 Pi to control relays and ...

Digital Green LED Clocks

sample of one of the clocks in the lab During the week of Oct. 24th, some small but vital improvements were made to lab. As most scientific experiments often do, many of the projects occuring at Spinlab require precise time keeping. It has been a long-haul battle getting the required clocks to function at optimum ...

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 ...

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 ...

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 ...
