The ALPHA Collaboration at CERN is engaged in an ambitious experimental programme to perform numerous precision measurements of antihydrogen atoms, including optical and microwave spectroscopy as was as direct gravitational acceleration measurements in order to precisely test CPT invariance, the weak equivalence principle, and Lorentz invariance. The antiprotons for these experimental efforts are provided by CERN’s accelerator complex and ALPHA’s unique antiproton catching trap.  CERN has recently upgraded its infrastructure to include a new antiproton decelerator, ELENA, in order to enable experiments to improve their antiproton capture efficiency. ALPHA is updating its antiproton catching trap and antiproton manipulation techniques to accommodate this new infrastructure.

This post will focus on commissioning and optimizing the operation of ALPHA’s antihydrogen trapping experiments. This will include experimental design and data analysis for antihydrogen experiments ranging from antimatter gravitation measurements to antihydrogen spectroscopy work in ALPHA’s experimental apparatus. Of particular interest in this post is the collection and analysis of annihilation data from ALPHA’s array of detectors. This will include the systematic study of antihydrogen annihilation events in on ALPHA’s silicon vertex detector, radial time projection chamber and barrel scintillator. A main focus on this work will be the identification and suppression of background signals. Additional studies will include acquisition and analysis of antiproton annihilations during experimental procedures which manipulate these particles directly.

You are required to have or be about to receive a PhD-level qualification or equivalent in physics related to the detection of antiproton annihilations, and analysis of vertex detectors using machine learning. You should have operational experience with the hardware and diagnostics typical of these experiments, including antimatter annihilation detectors and charge measurement devices. You should be expert in detector data analysis and simulation codes including atomic Monte Carlo simulations for modelling trapped antihydrogen behaviour. You will be based at CERN for the duration of this post and may be expected to travel as necessary for conferences and meetings.
