Master Student – Internship/Thesis: Development of an experimental setup for the photothermal lensing effect in gas sensing applications.

06.05.2026, Studentische Hilfskräfte, Praktikantenstellen, Studienarbeiten

Description:
Photoacoustic spectroscopy (PAS) is an analytical technique that leverages the photoacoustic effect, where modulated light absorption by a gas sample causes localized heating, thermal expansion, and the generation of pressure waves that can be detected as sound.

In this project at the Chair of Analytical Chemistry at TUM, we aim to develop a photoacoustic gas-sensing system tailored for biogas plant applications.

Possible tasks in the project:
-Design and implementation of an optical experimental setup for investigating Photoacoustic effect gas-sensing effects
-Calibration and characterization of the system using controlled conditions (pressure, flow, and humidity, etc.)
-Signal processing, data evaluation, and documentation of results

Your Profile:
-You are currently enrolled in a degree program in Physics, Chemistry, or another STEM-related field
-Initial laboratory experience, ideally with lasers and/or optical systems
-Basic understanding of spectroscopy, measurement technology, or sensor principles
-Familiarity with experimental data acquisition and analysis
-Strong communication skills in English
-Independent and structured working style


Start:
As soon as possible.

Location:
Our Team is located in Großhadern, Georg-Heberer-Straße 11.

Note:
This position is unpaid, and it is designed for Master's students as a research intern/thesis student.
