Coordinated Projects

The ToASt ASIC is a 64-channel integrated circuit developed for the readout of the Silicon strip detector project designed to be placed in the Micro-Vertex Detector of the PANDA experiment. ToASt is implemented in a commercial 110 nm CMOS technology and can provide information on the position, time, and deposited energy of the particle passing through the detector. [...]

The PANDA (antiProton ANnihilation at DArmstadt) experiment will study the strong interaction in annihilation reactions between an antiproton beam and a stationary cluster jet target. The PANDA detector will be composed of several sub-detectors designed for tracking, particle identification and calorimetry. [...]

Summary. — The new Facility for Antiproton and Ion Research (FAIR) is un-der construction at GSI in Darmstadt (Germany). [...]

This work aims to develop a non-destructive beam time structure monitoring system for the superconducting Darmstadt linear accelerator (S-DALINAC). The S-DALINAC is a 3 GHz superconducting electron accelerator capable of operations in the energy recovery (ERL) mode. [...]

The investigation of femtoscopic correlations between pairs of photons emitted from heavy-ion collisions offers a unique opportunity to investigate the evolving source spacetime characteristics and properties. Unlike commonly studied charged particle correlations, photons are not influenced by strong or electromagnetic interactions, and thus have a longer mean free path. [...]

Summary. — This work explores femtoscopic correlations in proton-proton andproton-cluster systems at the HADES experiment, GSI. [...]

An experimental study of $\gamma$-$\gamma$, $p$-$\Lambda$, and $p$-cluster femtoscopic correlations from Ag+Ag collisions at $\sqrt{s_{NN}} = 2.55 \ \text{GeV}$ has been conducted using the HADES detector. The results reveal an HBT-like structure for $\gamma$-$\gamma$ correlations, provide estimations of strong interaction parameters for $p$-$\Lambda$ correlations, and indicate potential decay signatures of light nuclei for $p$-cluster correlation functions..

In this contribution we will discuss the production of $\Sigma^{0}$ baryons in Ag+Ag collisions at $1.58 \, A\text{GeV}$ beam energy measured by HADES. The experimental upgrade with an electromagnetic calorimeter enables a clear reconstruction of the $\Sigma^{0}$. [...]

Preliminary results of inclusive $\sigma^{+}(1385)$ production in $p + p$ reactions at $E_{\text{beam}} = 4.5 \ \text{GeV}$ and $\Lambda(1520)$ in $p + p$ and $p + \text{Nb}$ at $E_{\text{beam}} = 3.5 \ \text{GeV}$ are presented. Both measurements were performed by the HADES (\emph{High Acceptance Di-Electron Spectrometer}) experiment at FAIR/GSI [...]

Abstract. Photons, as penetrative probes, can deliver information about early stages of heavy-ion collisions, in contrast to hadrons, whose kinematics are determined after the freeze-out era. [...]
