Working 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 Presentation for the DIAMOND SAC May 2002
Working Party Conclusions • 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 Presentation for the DIAMOND SAC May 2002
Working Party Conclusions • Ultra-high resolution mode • Double bounce analysers? • Analysers synchronised with monochromator • Low-angle detectors to be pixellated to remove effect of axial divergence • Negative 2q direction, 60° PSD • Saturation rate 1MHz • Data collection in 100s ms to s • Real-time monitor for parametric studies (VT, VTP, VH, etc.) • Positive 2q direction, 64 analysers & detectors Presentation for the DIAMOND SAC May 2002
Working Party Conclusions • 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 ££££ Presentation for the DIAMOND SAC May 2002
Working 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 Presentation for the DIAMOND SAC May 2002
Working Party Conclusions • 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?
