DESCRIPTION:Speakers: Brandt Gaches (Faculty of Physics\, University of Du
 isburg-Essen)\n\nEnergetic particles\, dubbed cosmic rays\, with a wide ra
 nge of compositions\, are important in driving chemical and thermodynamic 
 processes in the molecular interstellar medium. Cosmic ray protons and ele
 ctrons are important regulators of gas-phase chemistry through non-thermal
  ionizations and excitations. Heavy fast ions play a vital role in the rad
 iation chemistry in interstellar ices and the build-up of chemical complex
 ity in ices to prebiotic molecules. In the dense\, shielded regions\, the 
 cosmic ray-driven ionization sets the electron fraction\, controlling the 
 strength of non-ideal magneto-hydrodynamic processes.\nThe physics and che
 mistry of cosmic ray irradiation is naturally an inter- and multidisciplin
 ary problem. Their acceleration and transport exist in the realm of high-e
 nergy astrophysics and plasma physics. Understanding their role in interst
 ellar molecular chemistry requires investigations into fundamental microph
 ysics\, such as electron-molecular interactions\, and laboratory and compu
 tational chemistry. Finally\, placing the role of these small-scale proces
 ses in the larger astrophysical picture requires macroscopic chemical mode
 ls and observations across a wide range of photon energies.\nThe conferenc
 e aims to bring together an interdisciplinary group of experts\, from astr
 onomy\, chemistry\, and physics\, to improve our understanding of radiatio
 n chemistry from the microscopic (nanometer) to macroscopic (parsec) scale
 s. The conference will include a range of talks across different specializ
 ations\, and discussion sections to bring these diverse communities togeth
 er under a common goal and set of curiosities. \nNote: To avoid conferenc
 e fees\, the conference is limited to about 50 participants. Therefore\, w
 e urge all participants that if they cannot make it to the conference to i
 nform the SOC with sufficient notice.\nThemes:\n\n\nAstronomical observati
