"Postdoctoral Researcher in Antihydrogen Physics"

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-g experiment, in particular, employs magnetic fields to balance the effects of gravitational potential on antimatter. This project will perform the first attempt to quantitatively measure the acceleration of antihydrogen due to Earth's gravitational field through the stochastic application of dipole heating pulses on a trapped antihydrogen population. The selected candidate will be central to this effort and develop the optical system and experimental techniques for use in the ALPHA-g gravitation experiment. The project will also include the development of a H- dissociation for use in performing equivalent measurements with trapped hydrogen experiments in ALPHA. The successful candidate will also actively contribute to the broader ALPHA physics program, encompassing gravitational measurements and general spectroscopy campaigns.

Based at CERN, this experimental initiative involves manipulating trapped electron plasmas for use as magnetometers. It also entails developing and deploying electronics to enhance and optimize control of the antihydrogen magnetic trap system. Further, this candidate will help establish the development of stochastic acceleration of trapped anti-atoms for use in future gravitation experiments. The successful candidate will also actively contribute to the broader ALPHA physics program, encompassing gravitational measurements and general spectroscopy campaigns.

Qualifications for the role include substantial experimental experience with trapped ions or atoms. A background in atomics physics and familiarity with optics, high power lasers and associated instrumentation and control systems, are essential.
