Status of natural and magnetic circular dichroism instrumentation using synchrotron radiation

Since synchrotron radiation is intense, highly linearly polarized, a spectral continuum and collimated, it is ideal (necessary) for magnetic and natural circular dichroism measurements in certain regions of the spectrum. What these regions are, the importance of the measurements and considerations in instrumental design which preserve the ideal properties of synchrotron radiation are discussed. Then the design, present status and future plans are reviewed for each functioning instrument. Finally the instrumental design challenges of the future are surveyed.
