... Originally photons are in equilibrium with electrons: Electrons or positrons radiate photons: e --> e + And photons pair produce: e+ + e As the universe cools, the energy of the radiated photons falls below 2 x me = 1 MeV, and they can no-longer pair produce. ...

IMPROVEMENT OF THE MAGNETIC PROPERTIES OF Nd Fe B
... properties. Therefore, only a small amount of Dy precursor was required to improve markedly the coercivity of the Nd2Fe14B powders [13]. And multi domain particles like Nd2Fe14B are subdivided into homogeneously magnetized domains, in which magnetization is oriented along an easy axis. The transitio ...

Antiproton Decelerator
_Hall.jpg?width=300)
The Antiproton Decelerator (AD) is a storage ring at the CERN laboratory in Geneva. It was built as a successor to the Low Energy Antiproton Ring (LEAR) and started operation in the year 2000. The decelerated antiprotons are ejected to one of several connected experiments.
