Offer Description

The Group for Advanced Receiver Development (GARD) at Chalmers leads in Terahertz instrumentation for radio astronomy. Our team of scientists, physicists, and engineers focuses on superconducting electronics, terahertz technologies, material science, low-temperature physics, thin-film technology, and microwave engineering. This multidisciplinary approach allows us to create advanced instruments for radio astronomy and environmental sciences.

GARD, recognized internationally for its Terahertz instrumentation, has significantly contributed to projects like Herschel HIFI, ALMA, and APEX. As part of Onsala Space Observatory , GARD collaborates with astronomers to design future instruments for exploring the universe's greatest questions.

Project overview
Developing multipixel heterodyne receivers is essential for advancing astronomical and atmospheric research. These receivers enable simultaneous observation across multiple frequency bands, increasing data acquisition rates and telescope capabilities. This technology ensures efficient use of observation time, especially during limited THz observation windows. It also introduces multi-color operations, enhancing detailed mapping of the interstellar medium and improving atmospheric monitoring for understanding star formation and atmospheric chemistry.

This PhD project aims to develop an advanced terahertz multi-pixel heterodyne receiver using SIS and HEB technologies. The focus is on integrating broadband capabilities within the receiver design for efficient operation across terahertz frequencies, addressing complexities in developing advanced broadband terahertz waveguides and layouts, and overcoming challenges related to signal attenuation, diffraction limits, and thermal noise. Achieving compact, efficient designs for cryogenic environments is crucial for practical applications in radio astronomy.

Major responsibilities
As a PhD student, you will conduct research involving electromagnetic simulation, fabrication, and experimental measurements. You will develop scientific concepts and communicate findings both verbally and in writing. The position includes teaching responsibilities at the undergraduate level, accounting for approximately 20% of your time. A collaborative spirit, self-motivation, attention to detail, and strong problem-solving capabilities are essential.
