S. Yamamoto et al., IN-VACUUM UNDULATOR INSTALLED IN A 6.5 GEV STORAGE-RING FOR PRODUCINGBRILLIANT 14.4 KEV MOSSBAUER PHOTONS, Journal of applied physics, 74(1), 1993, pp. 500-503
Using a newly developed in-vacuum type undulator installed in the 6.5
GeV TRISTAN Accumulation Ring at the National Laboratory for High Ener
gy Physics, a beam comprising of more than 2.4 x 10(4) Mossbauer photo
ns/s at 14.4 keV has been achieved from an enriched alpha-(Fe2O3)-Fe-5
7 single crystal. The spectrum in terms of brilliance in the region fr
om 5 to 25 keV agrees well with the calculation.
