Effective management of the heat transfer into cryogenic piping and storage reservoirs is accomplished with low thermal conductivity insulation systems. Polymer aerogels are renowned for their low density, high mesoporosity, high internal surface area, low thermal conductivity, mechanically robust structural integrity, and high acoustic impedance. These unique properties present in one...
The Composite Cryogenic Hydrogen Insulated Lined (C-CHILL) Storage System, developed by Dynovas, addresses the need for advanced reusable liquid hydrogen storage. The C-CHILL system is engineered to support spacecraft, surface systems, and hydrogen aircraft requiring long-duration cryogenic hydrogen storage. Leveraging a Type IV composite overwrapped pressure vessel (COPV) with a carbon fiber...
Accelerator magnets based on Nb3Sn superconductor are often prone to severe training. Previous works in literature found that stored strain energy in the coil’s impregnant, usually epoxy resin, is released as heat during cracking, debonding and subsequent friction. This heat affects locally the temperature margin of Nb3Sn eventually leading to a quench, and it can contribute to elongated...
By using TELENE® resin as superconducting magnet impregnation material, training and magnet retraining after a thermal cycle were nearly eliminated in Nb3Sn undulators. This allows reducing operation margins in light sources, and increasing the on-axis magnetic field, thereby expanding energy range and brightness intensity. TELENE is Co-60 gamma radiation resistant up to 7-8 MGy, and therefore...
