J. Baruchel et al., PRESENT STATUS OF THE TOPOGRAPHY AND HIGH-RESOLUTION DIFFRACTION BEAMLINE AT THE ESRF, Journal of physics. D, Applied physics, 26(4A), 1993, pp. 9-14
We present a preliminary design of the topography and high-resolution
diffraction beamline (BL16, ID19) at the ESRF. Its main characteristic
s derive from the requirements of having a almost-equal-to 40 (horizon
tal) x 14 (vertical) mm2 spectrally and spatially homogeneous beam, a
high photon flux and a tunable photon energy at the sample position. T
his implies the choice of a high-field, 11-pole wiggler with a variabl
e gap as source, a 140 m long beamline, and different types of filters
. The experimental station is located in a satellite laboratory. The m
onochromators will either produce a wide- or a narrow-bandpass beam. T
he experimental hutch is designed to use either white or monochromatic
beams, and to host either instrumentation with a heavy sample environ
ment or with a high-precision setting for high-resolution diffraction
and topography. Finally we point out the facilities which will be avai
lable for beamline users.
