Energy Recovery Linac

Cornell University and Jefferson Laboratory physicists have been studying the properties of a new type of synchrotron radiation machine, called and Energy Recovery Linac (ERL), based on a superconducting linac and a one-turn return arc (like a storage ring). A 5 to 7 <nop>GeV, 10 to 200 mA ERL m achine could produce electron beams of a few microns diameter with very low emittances (8 to 100 pm) in both the horizontal and the vertical planes. Small gap undulators up to 25 meters in length can produce ultra-high brilliance x-ray beams with many desirable characteristics, including: transversely coherent, diffraction-limited hard x-rays of very short (~20 fs to 2 ps), frequent (1.3GHz) pulses, with no limits on beam lifetime and very flexible modes of operation. This combination of characteristics opens new possibilities and could significantly advance the state of the art in x-ray research.

NSF awards Cornell $18 million to develop a new source of X-rays
ITHACA, N.Y. -- The National Science Foundation (NSF) has awarded Cornell University $18 million to begin development of a new, advanced synchrotron radiation x-ray source, called an Energy Recovery Linac (ERL). The ERL, based on accelerator physics and superconducting microwave technology in which Cornell's Laboratory of Elementary Particle Physics (LEPP) is a world leader, will enable investigations of matter that are impossible to perform with existing X-ray sources.
