Figure 3.2 Comparison of the emitted power from two different synchrotron storage ring NSLS at 0.8 GeV, and SOLEIL at 2.75 GeV, with that of a blackbody at 2000 K. For SR, bending magnet radiation is considered, with collection angles of 40 mrad x 40 mrad (horizontal x vertical).

Synchrotron storage rings, for instance, are able to provide an extremely high flux of nearly monochromatic X-radiation on a small sample area. They could form the basis of XRF set-ups and enhance other microana-lytical methods to provide accurate determinations. In the future they could serve as a reference method for elemental trace analysis on the microscopical level (with the quality of the random number generator, a non-SI concept, as the prime source of error). [Pg.41]

In conclusion we may say that the time-resdved fluorescence depolarization experp ment provides a com nient and accurate n%thod for characterising complex molecular motion occurring in macromolecules. The Hmtted use of the technique to date has been due to the lack of high quality fluorescence decay time data. Improvements in experimental methods associated with the use of better excitation sources such as pulsed lasers or li t from synchrotron storage rings may well provide a renaissance in the use of the technique. [Pg.161]

The radiation is very intense and exceeds the available normal laboratory sources by up to 6 or 7 orders of magnitude. The synchrotron storage rings used for the radiation production, however, are large and expensive, with facilities characterized by storage rings with a circumference up to more than one thousand metres. [Pg.88]
