Energy doubling of 42 GeV electrons in a metre-scale plasma wakefield accelerator

Article Abstract:

An energy gain of more than 42 GeV is accomplished in a plasma wakefield accelerator that is driven by a 42 GeV electron beam at the Stanford Linear Accelerator Center (SLAC). The viability of plasma accelerators for high-energy physics is demonstrated by producing the energy gain of the 3-km-long SLAC accelerator in less than a meter for a small number of electrons.

Hexagonal nanoporous germanium through surfactant-driven self-assembly of Zintl clusters

Article Abstract:

Surfactant templating is a method that has successfully used to produce nanoporous inorganic structures from a wide range of oxide-based material. An attempt is made to show that it is possible to use surfactant-driven self-organization of soluble Zintl clusters to produce periodic, nanoporous versions of classic semiconductors such as amorphous Ge or Ge/Si alloys.
