Available positions

We have a post-doc  and a PhD position available,  please contact us for more information.

Further information on the post doc position:

There is an immediate opening for a Research Associate to work in the group of Professor David Cassidy on the production and spectroscopic investigation of positronium ions and molecules. The post will involve two main areas of research (1) the development of new positronium molecule and ion production methods and, (2) the development of a transform limited pulsed laser spectroscopy experiment. The ultimate goal of this work is to study excited states and resonances in Ps ions and molecules. The RA will be expected to contribute to all aspects of the experiment, and will take a leading role in planning and executing research strategies. There will also be opportunities to contribute to other experimental activities in the group, including precision positronium spectroscopy and interferometry measurements.

The successful applicant will have a PhD, in experimental atomic physics, physical chemistry, or a related subject. Hands-on experience with pulsed lasers and optical systems is essential. It is desirable that the candidate will have experience with ultra-high vacuum systems, basic electronics, and programming using Python. Prior experience with positron beams is not required. In the first instance please contact David Cassidy at d.cassidy@ucl.ac.uk

Further information on the PhD position:

There is an opening for a PhD student to join the group of Professor David Cassidy, working on a new project to develop experimental techniques to produce and study positronium atoms, ions, and molecules. This will involve the development of a positron microbeam, engineered positronium formation materials, and new spectroscopic techniques using pulsed laser systems. The ultimate goal of the research is to study excited states and resonances of Ps molecules and ions, and to perform fundamental measurements of physical constants via precision spectroscopy of Ps atoms. There will also be opportunities to work on other areas of research in the group, including manipulation of Rydberg atoms using inhomogeneous electric fields and antimatter gravity tests using Ps interferometry.

The studentship will cover tuition fees at the UK/EU rate plus a maintenance stipend for four years. Applicants should have, or be expecting to achieve, a first or upper-second class honours degree or equivalent in, physics, physical chemistry or a related subject. They must also have effective written and verbal communication skills in English.

Interested candidates should contact d.cassidy@ucl.ac.uk with a CV and a motivation letter explaining their interest in this project. Informal enquiries are encouraged, and applications will be reviewed beginning 28 FEB 2020.
