Energy Doubling of the SLAC 28.5 GeV Beam in 60 cm Possible
If successful E167 will try doubling the 50 GeV Beam
“Accelerator Moore’s Law”
Current Energy Frontier
All these issues can be addressed with SABER
Spot Size=10 micron

E162: Positron Focusing
Can we focus e+,e- SABER beams to submicron dimension using plasma lenses?
Can we design layered structures as lenses for obtaining nanometer spot sizes?
