Intense Source of Slow Positrons
P. Perez, A. Rosowsky
We describe a novel design for an intense source of slow positrons based 
on pair production with a beam of electrons from a 10 MeV accelerator 
hitting a thin target at a low incidence angle. The positrons are collected
with a set of coils adapted to the large production angle. 
The collection system is designed to inject the positrons in a
Greaves-Surko traps.
Such a source could be the basis for a series of experiments in fundamental 
and applied research and would also be a prototype source for industrial 
applications which concern the field of defect characterization in the 
nanometer scale.
