Measuring the Yb Atomic Beam Flux

  On Monday, December 5th the SADiCS team led by Kristen Parzuchowski performed an improved Yb flux measurement. Several improvements were implemented including covering the measurement chamber with a non-reflective black foil to reduce stray light and conducting a more precise scan over wavelengths to find the resonance wavelength of Yb. This measurement took the ...

Fluorescence Spectrum of Impurities in Sapphire

  In the week of Dec. 5th a first analysis of the background of a sapphire substrate was performed. The measurements were performed be Evan Ryan, an undergrad working for the SADiCS project. The graph below shows the scattering and fluorescence response of impurities within the sapphire substrate when illuminated with light at a wavelength ...

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 in the event that one of ...

Demodulation Analysis of NMR Signals

The “Weekly Win” for the week of Nov. 21 was awarded to Jake Huneau for rewriting the program which uses a demodulation technique of analysis for the HeXe collaboration. The demodulation technique uses trigonometric identities and a digital lowpass filter to extract frequency and amplitude from the dataset. The benefit of this technique is that it creates ...

Emission Spectrum of 375 nm LED

The Weekly Win for the week of Nov. 14 was awarded the SADiCS team. The team led by undergraduate Evan Ryan focused on a detailed characterization of one of the light sources used for the Yb fluorescence measurement. This light source is an LED characterized by a central wavelength of 375nm. This LED is used as a ...

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 ...

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 Ready, Jake Huneau, and Kristen ...
