   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : WULLSCHLEGER LÉA; [2023]
   Keywords : Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

   Abstract : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. READ MORE

3. 2. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

   Author : Tim Günter; [2022]
   Keywords : ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

   Abstract : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. READ MORE

4. 3. Scattering Kernel Calculations for Liquid Para-Hydrogen Using Ring Polymer Molecular Dynamics

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Pontus Nordin; [2020]
   Keywords : Neutron scattering; Para-hydrogen; Scattering kernels; Molecular dynamics; Ring polymer molecular dynamics; ESS; Physics and Astronomy;

   Abstract : The European Spallation Source will be a world leading neutron source available for a range of neutron scattering experiments in the scientific community. In order to accurately simulate the production of cold and thermal neutrons, an accurate calculation of the neutron cross section for the moderator materials is needed. READ MORE

5. 4. Cold Moderator Hydrogen Flow and Cooling

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Mateusz Pucilowski; Paal Wenaas Smeby; [2014]
   Keywords : Liquid Hydrogen; Cryogenic Liquid; Conjugate Heat Transfer; Technology and Engineering;

   Abstract : In this master thesis, cold moderator flow concepts have been developed on behalf of the European Spallation Source, ESS AB in Lund. The function of the cold moderator is to slow down neutrons, generated in the spallation process. The moderation is done in liquid para-hydrogen at 15 bar and 17 K. READ MORE
