Skipper CCD Spectrograph

Student project: Dalys Guajardo and Mason Jelken

Our lab is teaming up with Fermilab and the University of Illinois Urbana-Champaign to explore a quantum spectroscopy application that utilizes a Skipper CCD for counting photons from a fiber-fed spectrograph on an optical bench. Our students are designing and building the spectrograph required to disperse the light onto the CCD. The goal is for the final application to detect nanometer shifts in the spectrum.
