Improvements in Quality of X-ray Beams 1)
Development of Wigglers and Undulators -
Increased Intensity and Brightness -
Experimental Facilities R D 2) Increased
Brightness - Better Focussing of Electron
Beams - Beam divergence and cross sections
reduced - Accelerator R D (reduced
emittance) 3) Increased Electron Beam
Current - Improved RF Systems, Electron
Guns - Accelerator R D 4) Improved Electron
Beam Stability (Accelerator R D) - Control
of Mechanical Vibrations - Improved Orbital
Feedback Systems - Thermal Stability to
maintain orbits
