“…Several synchrotron beamlines have been built world wide for the study of chemical dynamics [2][3][4][5][6][7][8][9][10][11]. They serve as an alternative to common laboratory sources of ultraviolet and vacuum ultraviolet radiation such as laser systems and discharge lamps.…”

“…For energies above 10 eV there is no suitable solid window material. The use of gas filters has become the preferred method [5,6,13,14] besides low-pass filters based on reflection. [15] Gas filters are efficient differential pumping systems and are most often used with noble gases such as Ar, Ne or even He.…”

“…[15] Gas filters are efficient differential pumping systems and are most often used with noble gases such as Ar, Ne or even He. [6] The challenge is to keep the pressure low enough at each end of the filter for the proper operation of the beamline and yet to reach a high-enough photoabsorption efficiency in the filter for the suppression of higher harmonics. In the past, gas filters have been rather bulky installations with a minimum length of 1.40 m [13] and powerful pumping systems were required.…”

An ultrahigh resolution and high-flux undulator beamline U9-CGM, with a cylindrical grating monochromator and covering an energy range from 5 to 100 eV, has been constructed. Two separate entrance slits are included to provide different incident angles, hence to optimize the overall performance. This beamline delivers an average photon flux of 6 ϫ 10 10 photons/ s with the entrance and exit slit openings at 10 m. An energy resolving power of 110 000 with a photon flux of 1 ϫ 10 10 photons/ s was obtained at 16 eV with the 1800 line/ mm grating and at 64 eV with the 1600 line/ mm grating, with the entrance and exit slit openings at 3 and 5 m, respectively. A differentially pumped gas cell is used to attenuate high-order light by up to four orders of magnitude. This beamline will be a powerful tool for research in ultrahigh resolution spectroscopy of atoms, molecules, and condensed matter.

A novel design for a differential pumping system has been investigated. This system allows windowless experiments in a soft X-ray beamline under normal atmospheric conditions. The new design consists of an aperture-based four-stage differential pumping system, based on a simple model calculation. A prototype system with a total length of 600 mm was constructed to confirm the validity of the design concept. Relatively short conductance-limiting components allow easy installation and alignment of the system on a synchrotron beamline. The fabricated system was installed on a beamline to test the transmission of soft X-rays through atmospheric helium.
