The Astroparticle and Dark Matter groupat the Center for Cosmology and Particle Physics Phenomenology (CP3)at the Department of Physics Chemistry and Pharmacyat the University of Southern Denmark (SDU)invites applications for a PhD position in Experimental Particle Physics with a focus on cryogenic single-photon detectors for axion searches.
The successful candidate will contribute to the development of background-suppression techniques for singlephoton detectors used in axion experiments operating at optical and infrared wavelengths. The research project includes the installation and characterization of a cold optical filter bench inside a dilution refrigerator and the evaluation of its performance when coupled to a transition edge sensor (TES) or superconducting nanowire singlephoton detector (SNSPD). Additional responsibilities include developing efficient coupling of freespace optics to optical fibers conducting extended datataking runs with TES and SNSPD systems and performing data analysis. Contributions to the development of novel experimental designs for dark matter axion searches are also possible.
Our groupprovides hands-on access to state-of-the-art cryogenic facilities and the opportunity to work within major international research collaborations. CP3is embedded in a vibrant and interdisciplinary research environment at SDU with close ties to leading groups in lightmatter interactions and nanophotonics as well as to theoretical physicists in the Department of Mathematics and Computer Science. We collaborate closely with scientists of the ALPS II collaboration and parts of the experimental work will be carried out at DESY Hamburg.
Applicants should indicate whether they are applying for a 3year PhD position in which case a Masters degree (or equivalent qualification) in physics or a closely related field is required or for a 4year integrated Masters and PhD program.
Essential qualifications include:
Experience in cryogenics data analysis programming nanophotonics and working in international research teams or collaborations will be considered an advantage.
