Advancements in TOF-PET using DOI Capable Modules and Low-Noise High-Frequency Readout
/ Terragni, G (CERN ; Vienna U.) ; Kratochwil, N (CERN) ; Lowis, C (CERN ; RWTH Aachen U.) ; Pagano, F (CERN ; INFN, Milan Bicocca) ; Cates, J W (LBNL, Berkeley) ; Pizzichemi, M (CERN ; INFN, Milan Bicocca) ; Marton, J (Vienna U.) ; Auffray Hillemanns, E (CERN)
Achieving good time resolution has become a prerequisite in positron emission tomography (PET) to improve the signal-to-noise ratio and thus the quality of the reconstructed image. A particularly attractive solution for the electronic readout is using low-noise high-frequency circuits (HF), which have demonstrated excellent timing performance in time-of-flight (TOF)-PET applications.

Comparison of timing and DOI performance of light-sharing TOF-PET modules with different readout electronics
/ Terragni, G (CERN ; TU Vienna) ; Nadig, V (RWTH Aachen U.) ; Di Gangi, S (Milan Bicocca U.) ; Marton, J (TU Vienna) ; Schulz, V (RWTH Aachen U.) ; Gundacker, S (RWTH Aachen U.) ; Pizzichemi, M (CERN ; Milan Bicocca U.) ; Hillemanns, E Auffray (CERN)
Time resolution plays a key role in positron emission tomography (PET) by enhancing the signal-to-noise ratio and ultimately improving the quality of the image. In previous studies, an array of 16 LYSO crystals (measuring 3.1x3.1x15 mm$^3$) coupled to Hamamatsu S13361-3050AE-04 SiPMs and readout by a custom-made NINO board achieved a coincidence time resolution (CTR) below 160 ps.

Hyperon signatures in the PANDA experiment at FAIR
/ PANDA Collaboration
We present a detailed simulation study of the signatures from the sequential decays of the triple-strange pbar p -> Ω+Ω- -> K+ΛbarK- Λ -> K+pbarπ+K-pπ- process in the PANDA central tracking system with focus on hit patterns and precise time measurement. [...]

Forming a pulsed beam of cold antihydrogen using charge-exchange with Rydberg positronium (Ps) is the goal of the AEḡIS collaboration, which aims to a first gravity measurement on neutral antimatter. Recently achieved results in Ps formation and laser spectroscopy in the main AEḡIS apparatus are summarized. [...]

We report on recent developments in positronium work in the frame of antihydrogen production through charge exchange in the AEgIS collaboration [1]. In particular, we present a new technique based on spatially imaging a cloud of positronium by collecting the positrons emitted by photoionization. [...]

From the experimental point of view, very little is known about the gravitational interaction between matter and antimatter. In particular, the Weak Equivalence Principle, which is of paramount importance for the General Relativity, has not yet been directly probed with antimatter. [...]

The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is a CERN based experiment with the central aim to measure directly the gravitational acceleration of antihydrogen. Antihydrogen atoms will be produced via charge exchange reactions which will consist of Rydberg-excited positronium atoms sent to cooled antiprotons within an electromagnetic trap. [...]
