WebA hypernova is an extremely powerful and rare type of supernova explosion that is believed to occur when a massive star, typically more than 30 times the mass of our sun, collapses in on itself at the end of its life cycle. During a hypernova, an enormous amount of energy is released, creating a burst of gamma-ray radiation that can be detected from Earth. These … Web3) can be sputtered as well as evaporated. Niobia (Nb 2O 5) has become a favored material because it provides higher sputter rates than the other high-index materials. The fluorides used at the shorter UV wavelengths are typically evaporated from resistance-heated containers but can be E-beam evaporated at low power.
