107. M1Or4A-01: [Invited] Thermal Conductivity of Polymer Aerogels at Different Vacuum Levels for Cryogenic Insulation Applications

Ryan Ehresman (LeTourneau University)

5/19/25, 4:15 PM

Invited Oral

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...

442. M1Or4A-02: Composite cryogenic hydrogen insulated lightweight lined storage (C-CHILL)

Sascha Stevens (Dynovas)

5/19/25, 4:45 PM

Contributed Oral

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...

245. M1Or4A-03: [Invited] Quantifying the relation between strain energy release rate and heat generated in the CTD-101K epoxy resin magnet impregnant at cryogenic temperatures

Prof. Herman ten kate (University of Twente)

5/19/25, 5:00 PM

Invited Oral

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...

439. M1Or4A-04: Elimination of Training in Nb3Sn and NbTi Superconducting Magnets

Elena Tamagnini

5/19/25, 5:30 PM

Contributed Oral

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...
