Future Trends in Structural Crystallography by Powder Diffraction

Future Trends in Structural Crystallography by Powder Diffraction

• Laboratory X-ray Diffractometers– Limited scope for orders of magnitude improvements

• Faster and better detectors

• Neutron Powder Diffractometers– Count rate on modern machines vastly improved

• e.g. GEM at ISIS

• Synchrotron Powder Diffractometers– Move of BM16 to ID31 at ESRF– Beamline H on DIAMOND


Background to Beamline HBackground to Beamline H• September 2001 SRS User Meeting

– List of Possible Beamlines Required on DIAMOND– E-mail Invitation for "Expressions of Interest"

• Organised by Graham Bushnell-Wye

• Open Meeting held at Birkbeck in October 2001– Approx. 30 Attendees– Topics

• Insertion Devices (Mike Poole) & BM16/ID31 (Andy Fitch)• Science• High-Resolution versus High-Flux Diffractometers• User Instrument


Initial ProposalInitial Proposal• Three Page Initial Proposal for a High-

Resolution Powder Diffraction Beamline Submitted on Behalf of the UK Powder Diffraction Community in November 2001– With much help from from Chiu Tang, Paolo Radaelli,

Bill David, John Evans

• Of the 16 Initial Proposals, 6 Shortlisted by the SAC in January 2002– A High-Resolution Powder Diffraction Beamline for

Structural Crystallography Short-Listed as

"BEAMLINE H"

Working Party ConclusionsWorking Party Conclusions

• User-friendly beamline for the non-expert– As easy to use as the laboratory diffractometer

• Ultra high resolution, but– Rapid high-resolution powder diffraction data required in minutes

and not in hours!!!

• Energy range from 5 to 30+ keV– Limits imposed by the choice of a medium energy (3 GeV) source – Optimised in 10 to 20 keV range– ESRF available for those requiring very hard (>30 Kev) X-rays

• Wavelength range from 2.5 down to 0.4 Å



• Optics: in vacuo narrow-gap undulator is essential:

– High brightness with narrow horizontal divergence• No need for beam focussing (simple optics)• No requirement for mirrors (more user friendly)

– Provides a continuous range of wavelengths over the desired wavelength range

• Ability for the user to change wavelength at the "click of a mouse"

– EXAFS quality monochromator with double Si(111) crystals– Fixed beam entry/exit with detuning for harmonic rejection


Working Party ConclusionsWorking Party Conclusions• Positive 2 direction, 64 analysers & detectors

• Ultra-high resolution mode• Double bounce analysers?• Analysers synchronised with

monochromator• Low-angle detectors to be pixellated

to remove effect of axial divergence

• Negative 2 direction, 60° PSD• Saturation rate 1MHz• Data collection in 100s ms to s• Real-time monitor for parametric

studies (VT, VTP, VH, etc.)



• Typical modus operandi :– collection of PSD diffraction data while the

sample is undergoing some of change of state – switch to high-resolution mode once sample

equilibrium has been reached

• Obtain a complete experiment on the same sample on the same instrument

• One disadvantage: additional ££££


Working Party ConclusionsWorking Party Conclusions• Separate optics & experimental hutches• Large amount of space in experimental hutch

– Avoid SRS situation of cramped working conditions!

• Sample automation of the utmost importance– High throughput as in PX– Use of robotic sample changers– Automatic alignment

• Easy to use sample heating/cooling stages, variable humidity, gas, electric and/or magnetic field, etc.

– Must be available on Day 1

• Integrated & user-friendly control software– Must be properly budgeted



• User control hutch and user data analyses rooms

– Multiple PCs & plug-in laptop facilities– Appropriate analysis software– Colour printing "on tap"– Data archiving facilities

• User laboratories close to beamline– Well-equipped for various sample manipulations– Share laboratories with beamline 1 & a single

crystal beamline?
