Research Assistant in Antimatter Physics
We are seeking to appoint an person to aid in the construction and commissioning of a PELLIS hydrogen ion source aimed at specialised use in the production and diagnosis of hydrogen atoms in the ALPHA antihydrogen experiment. The successful applicant should have familiarity with accelerator physics, as well as a detailed background about the theory of the operation of ion sources and subsequent beam extraction. They should also be ready to understand and contribute to the specific technical details of this source installation, including the design of mechanical and electrical systems associated with the source, as well as design and operation of control and diagnostic software. The role will be partially based at CERN and report to Dr. William Bertsche.
Along with your application, you should submit a single file containing your CV, list of publications, and research statement (max 2 pages).
The ALPHA experiment at CERN addresses a key challenge in physics – understanding the disparities between matter and antimatter that have shaped our matter-dominated universe. Focused on precise atomic physics measurements, the project aims to uncover minute differences between trapped antihydrogen and hydrogen atoms. In the realm of antimatter gravitation and spectroscopic studies, achieving the highest precision demands meticulous control and understanding of the magnetic environment.
The ALPHA experiment performs precision experiments with antihydrogen atoms that are formed through direct combination of positrons and antiprotons. To date, comparison of antimatter experiments to matter experiments relies on comparing detailed simulations of assumed matter behavior in traps against empirical measurements. This project will take the first steps towards making direct comparisons of the behavior of hydrogen atoms in the ALPHA experiment to antihydrogen results by commisioning an ion source for use in the production of hydrogen atoms in ALPHA.
This experimental initiative involves the organisation, installation, and initial testing of the ALPHA PELLIS ion source on a test chamber at CERN. This project will aim to install and operate the PELLIS source on a test experiment in advance of incorporation in the ALPHA experiment, and establish similar performance of the source to its use at RAL. The installation work will involve modification and extension of an existing test chamber to accept the PELLIS source, installation of source hardware, modification and extension of test chamber diagnostics to validate source operation, tracking purchasing of and installation of commercial hardware for operating source electronics, development of simple test software to operate the above.
Qualifications for the role include an MSc or equivalent degree in physics, with a focus on accelerator science or related fields. The successful applicant should have a background knowledge on the principles and operation of charged particles sources and beam transport. Applicants should have experience with mechanical modelling and experience electronics and electronics testing. Practical experience with particle tracking will be critical to interpreting commissioning results. Significant portions of the effort will take place at CERN in Switzerland, and candidates should be
