Project description
A powerful approach to test matter-antimatter interactions
Antiprotonic atoms are exotic atoms formed when an antiproton replaces an electron, offering a way to study the interactions between matter and antimatter. Supported by the Marie Skłodowska-Curie Actions programme, the TESAAS project aims to advance their study by adapting X-ray detectors called superconducting transition-edge sensors (TESs). TESAAS will introduce new TES designs to overcome challenges including electron refilling effects and radiation interference. Project work will focus on three areas: specially designed TES pixels for antimatter environments, a gas-target system to control electron dynamics, and a detector array to track charged particle backgrounds. This powerful set-up will enable researchers to explore quantum electrodynamics in strong electric fields, test beyond Standard Model physics and contribute to atomic, nuclear, and particle physics.
Objective
The spectroscopy of antiprotonic atoms with the use of next-generation quantum sensing x-ray microcalorimeters has the potential to benchmark Quantum Electrodynamics (QED) effects in strongest electric fields attainable in the lab. With attainable precisions of dE/E = 10E-5 it is possible to test 2-loop QED vacuum polarization effects well beyond the Schwinger limit, place strict limits on neutron skin thicknesses and, potentially, place constraints on certain classes of beyond Standard Model physics.
Transition Edge Sensors for Antiprotonic Atom Spectroscopy (TESAAS) is a project concerned with adapting x ray detectors called superconducting transition edge sensors (TESs) to the challenges of antiprotonic atom x-ray spectroscopy through the development of new TES designs and a complete experimental end-station that addresses the dominating sources of uncertainty in these measurements, namely electron refilling effects and radiation backgrounds from annihilation products. TESAAS entails three major efforts which build on my work with TESs for antiprotonic atom x-ray spectroscopy: 1) The development of a novel TES pixel design optimized for the noise and radiation environments of antimatter facilities 2) Simulation assisted design of a gas-target system with which to control the impact of electron refilling effects and 3) The construction of an auxiliary detector array capable of monitoring the intensity of charged particle backgrounds produced in the antiprotonic atom decay process.
These will come together to form a complete experimental end-station capable of unlocking the use of Transition Edge Sensors for use in antimatter studies. The availability of this powerful new method opens the door to a new generation of high precision measurements with transverse applications in atomic, nuclear, and particle physics.
