Over distances hardly more than the thickness of a coin, such laser "wakefield" accelerators
can pump electrons to high energies, the scientists report.
The binary combination of TEBA with N-oxy diethylene benzthiazyl sulfenamide(NOBS) and other accelerators
exhibit mutual activity.
The activity of accelerators
is determined to a great degree by the rate and extent of crosslink formation.
In contrast, the aging accelerators
now used for proton therapy were designed for basic physics research and are located in nonhospital settings.
Introduction In spite of the fact that some organic compounds used as accelerators
are added in small amounts (1-2 phr), they play a very important role in determining the physicomechanical properties of the obtained rubber vulcanizates (refs.
The collider, located at the Stanford Linear Accelerator
Centers (SLAC) at Stanford University, consists of two main parts: a 22-year-old, extensively modified, 2-mile-long linear accelerator
and a newly built section, resembling a pair of pincers at the end of a long, thin handle, carrying electrons and positrons along opposing arcs to the collision point (see diagram).
Whereas most high-powered electron accelerators
hurl "pulses' of electrons, all bunched together, toward the target nucleus, CEBAF is designed to shoot the electrons in a single-file stream.
