Synchrotron radiation for long wavelength spectroscopy
- 21 Downloads
A fundamental radiometric measurement has been carried out in the spectral region 1–140 cm−1 which demonstrates the higher brightness of the synchrotron radiation source at Daresbury Laboratory over a high pressure mercury arc lamp source. Comparison of the output powers from the SRS and the mercury lamp revealed that the SRS has a particular advantage in the region where the wavelength of the emitted photon becomes very longer. The gain factor of the SRS at 10 cm−1 was at least 10 times of the mercury lamp at a storage ring current of about 90 mA.
A single period wiggler is considered to be a favorable device which will provide a higher level of photon fluxes from an electron storage ring in the long wavelength region.
