Project Description

Fourier Transform Spectroscopy for CLASS Telescope Noise Reduction

The Cosmology Large Angular Scale Surveyor (CLASS) is an array of four microwave telescopes under construction at the physics department at Johns Hopkins University, falling under the joint supervision of Prof. Tobias Marriage. My proposed project for the upcoming summer of 2015 is to assemble, program and calibrate a Fourier transform spectrometer to be equipped onto one of the CLASS telescopes. The function of the spectrometer will be to filter out frequency ranges of electromagnetic noise that may contaminate the cosmic microwave background. One of the key tasks at hand is to align the microwave mirrors of the interferometer so as for input light to couple correctly with the CLASS receivers. With the setup in place, I will then program the spectrometer to produce relevant spectrum output. I will further calibrate the spectrometer based on initial test results until desired results are achieved.
