Doctoral Researcher in Experimental Nuclear Physics

Descrizione

Doctoral Researcher in Experimental Nuclear Physics Sintesi in italiano (traduzione automatica): Il Dipartimento di Fisica dell'Università di Jyväskylä cerca un Ricercatore Dottorale per il progetto DopCool, finanziato dal Research Council of Finland. La posizione, che avrà inizio a gennaio 2027 e durerà 3,5 anni, è finalizzata alla realizzazione di una tesi di dottorato. Il progetto si concentra su tecniche di raffreddamento laser per ioni radioattivi a vita breve, con applicazioni nella fisica delle particelle e nella terapia oncologica. I candidati devono possedere o essere prossimi al conseguimento di una laurea magistrale in fisica o in un campo correlato. È preferibile avere esperienza in fisica atomica, nucleare o delle particelle, sistemi laser, spettroscopia laser e analisi dei dati. La posizione offre un ambiente internazionale e opportunità di formazione pratica in tecniche avanzate di laboratorio. The Department of Physics is seeking to recruit a Doctoral Researcher within the newly funded Research Council of Finland project DopCool (Doppler and Sympathetic Cooling for Ultra-High Precision Mass Measurements of Short-Lived Radioactive Ions), hosted at the IGISOL facility within the Accelerator Laboratory of the University of Jyväskylä. The position will start in January 2027, or as soon as possible thereafter, for a period of 3.5 years. The position is fixed-term, as it is expected to lead to the completion of the doctoral thesis. The project will pioneer laser-based cooling techniques for short-lived radioactive ions and establish a new experimental paradigm for ultra-high-precision mass measurements at the IGISOL facility and beyond. Using lasers, the ions will be slowed and cooled close to absolute zero before injection into the JYFLTRAP Penning trap mass spectrometer. The ultra-high-precision mass measurements will be key to testing the limits of the Standard Model of particle physics and to exploring possible new physics. Mass measurements will also be performed to improve decay heat calculations in nuclear reactors and to refine dose estimates in targeted radionuclide therapy, a highly promising and rapidly emerging form of cancer treatment. Furthermore, the doctoral researcher will have opportunities to participate in mass measurements for nuclear structure and nuclear astrophysics studies and to collaborate with researchers from all over the world. The doctoral researcher will work in an international environment at the IGISOL facility, within the Accelerator Laboratory of the University of Jyväskylä. The facility is used to conduct research at the intersection of fundamental symmetries, nuclear and atomic physics using techniques in laser spectroscopy, mass spectrometry and ion trapping. The position offers extensive hands-on training in laser systems, ion trapping, precision instrumentation and data analysis, in the environment of a large-scale experimental facility. The position will provide excellent preparation for careers in academia, research institutes/laboratories and high-technology industries. Depending on the candidate’s interest and expertise, the work will include: Develop laser-cooling techniques for trapped ions including the setup and operation of laser systems Optimize the laser-cooling trap built by our collaboration partners from KU Leuven, Belgium Design, commission and optimize beam-manipulation devices for optimal ion injection into the Penning trap Integrate the laser-cooling trap with the JYFLTRAP Penning-trap mass spectrometer Study ultracold ion ensembles and their application to precision mass spectrometry Analyze and interpret high-precision mass measurements Participate in experiments at the IGISOL radioactive-ion-beam facility Develop and apply simulation tools for an improved understanding of the ion motion and cooling dynamics Present scientific results at international conferences and publish in peer-reviewed journals Who should apply Applicants should hold, or be close to completing, a Master’s degree in physics or a related field. Experience in one or more of the following areas is considered advantageous, but not required: Experimental atomic, nuclear or particle physics Laser systems and laser spectroscopy Ion trapping and charged-particle manipulation Mass spectrometry Vacuum technology and instrumentation Electronics, data acquisition and/or scientific programming (e.g. Python) Simulations (e.g. SimIon or Comsol) and/or data analysis Strong motivation for experimental research, excellent problem-solving skills, the ability to work effectively in an international research environment, and good written and spoken English skills are essential. The tasks of a Doctoral Researcher focus on research aiming at the completion of a doctoral thesis, doctoral studies, assisting teaching tasks, and other related tasks to these.
