APPENDIX C
REPRESENTATIVE SYNCHROTRON RADIATION SOURCES
Note that data are presented for 0.1% bandwidth from the source. Realizing this level of resolution at the experiment would generally require an optical system (monochromators, filters, etc.) that would reduce the power at the sample by a factor of ten or more.
