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 noise floor of 〜270℃ from our previous measurement and lowered it to 〜240℃.
This plot shows a much closer agreement between experimental data and simulated atomic flux when compared to the previous measurement. Currently, work is being done to develop a more sophisticated simulation and to achieve a high repeatability for Yb flux measurements. This work is crucial for a proper calibration of our atomic beam source.
