Helium swelling behavior for neutron multipliers after irradiation with He ions at high temperatures

Nuclear Materials and Energy
Beryllides as beryllium intermetallic compounds are the advanced multiplier materials as candidate materials for fusion demonstration power plant (DEMO) due to having good properties such as low swelling rate and stable chemical properties.Under DEMO ...

Evidence for a High-Temperature Disorder-Induced Mobility in Solid $^4$He

, 2010
We have carried out torsional oscillator experiments on solid $^4$He at temperatures between 1.3K and 1.9K. We discovered phenomena similar to those observed at temperatures below 0.2K, which currently are under debate regarding their interpretation in ...

Formation rates of core collapse SNe and GRBs

, 2003
We study the evolution of stars that may be the progenitors of long-soft gamma-ray burst (GRBs) -- rotating naked helium stars presumed to have lost their envelopes to winds or companions. Our aim is to investigate the formation and development of single
