Dear Morpholino, In 1985 on a second generation synchrotron Xray source we, Daresbury SRS with Stanford SSRL staff, could mimic the on paper monochromatic undulator intensities of the proposed “New Rings“ of the 3rd generation with a focussed SRS white beam and thus showed that a gramicidin crystal of average dimension of 20 microns could be studied with Xray diffraction methods:- https://www.pnas.org/content/82/22/7604 So, the ESRF Foundation Phase Report published in 1987, the Red Book, included as a practical plan a microfocus beamline for MX, envisaging then protein crystal samples of 20 microns or less should be feasible for XRD. The “or less” was a hope. Initially we, the MX community, had to be accommodated on a generic, shared, High Brilliance beamline at ESRF as we were not the only community eager to access such high intensity microfocus monochromatic Xray beams. Best wishes, John Emeritus Professor John R Helliwell DSc
