A plane-grating monochromator beamline for the PTB undulators at BESSY II.

At the BESSY II storage ring, the Physikalisch-Technische Bundesanstalt (PTB) will operate insertion devices dedicated to radiometric use. One branch of the appendant beamline system will be equipped with a grazing-incidence monochromator, described here. The monochromator concept is based on a plane grating operated in parallel light; therefore exact focusing is maintained for all photon energies irrespective of the angular setting at the grating. The monochromator has been optimized for small higher-order transmittance and high power throughput, as required by radiometric applications in the wide photon energy range from 20 eV to 1900 eV.

[ Ulcerative colitis and pregnancy].

Ulcerative colitis is a disease confined to the colon in an age from 20 to 40 years mainly. Fertility and pregnancy are not disturbed generally. The influence of pregnancy on the course of the colitis is not foreseeable, however. The therapy with Salazosulfapyridine is possible in pregnancy, too.
