2023 - 2024: Python Interface and Autonomous Scanning for FTMW Spectrometer

Under Dr. Gurusinghe at the Tennessee Technological University, a novel L-shaped FTMW (fourier transform microwave) spectrometer is being developed. FTMW spectroscopy is a revolutionary technique to investigate molecular energy transitions between quantized rotational states.

Marton joined the team to develop overarching software controlling synthesizers, actuators, oscilloscopes, and delay generators to streamline spectrometer operation. The software's integration allowed for the further development of algorithm based methods of calibration via data analysis and autonomous control of spectrometer components.

This python software is the first of its kind in the niche realm of FTMW spectrometers of which only several exist. Research was presented at several conferences, including the International Society of Mass Spectroscopy, and research publications are in development.

Laboratory Setup

Laboratory setup for FTMW spectrometer and associated components.

Results of Calibration (Second Iteration)

Second calibration iteration exposes possible regions of interest for mirror actuation positioning based on detected intensity of output signal.

Results of Calibration (Third Iteration)

Third calibration iteration positions mirror actuator within ±10µm of strongest possible signal (±0.0025% error).

2022 - 2023: Effect of Thermal Gradient on Diffusion Through PTFE Membrane

Assisting development of an Industry 4.0 capable underground sensor for qualifcation of environment specific soil profile, Marton conducted research to determine the feasibility of PTFE membranes as a semi-permeable diffusive barrier. Gaseous diffusion analysis was conducted with custom built diffusion testing apparatus in conjunction with mass flow sensors, Vernier/Gaslab software, gas detectors, custom heat exchangers, thermocouples, and more. Full mass balance was conducted with varying temperature gradient and results presented at an American Institute for Chemical Engineers conference.
