A 2 to 4 nm high power FEL on the SLAC linac

Abstract

SLAC-PJB-5948 DE93 004091 producing a radiation beam witha brightness eight orders ofmagnitude larger than synchrotron light sources, and pulse duration shorter than one picosecond. Such a large increase in radiation A 2 to 4 nm HIGH POWER FEL ON THE SLAC LINAC* flux, and the short pulse duration, will open new exciting and unique research possibilities in C. Pellegrini, J. Rosenzweig physics, biology and other sciences.

Self-amplified spontaneous emission for short wavelength coherent radiation

“…There has been extensive discussion of using a special bypass of a storage ring [11]. Recently, the use of linacs are actively discussed [ 12] due to the development of high-brightness RF photocathodes [ 13]. It appears that SASE based cn such accelerators are a promising way to generate multi-gigawatts of coherent power in the "water window" region.…”

High-intensity laser synchrotron x-ray source

“…Such devices are in operation at visible and IR wavelengths. A proposal has been put forward to build an FEL for the soft x-ray range making use of the 2-mile long linac at SLAC [4].…”

Coherence and linewidth studies of a 4 nm high power FEL

“…We adopt, as a "standard case", the parameters of Ref. [1]; namely, I b = 2 :5 kA and " n rms = 3 :0 mmmrad. The rms beam radius of 66 m corresponds to that expected from external quadrupole focusing with = 1 0 m. Note that this focusing is much greater than the "natural" wiggler focusing.…”
