PANalytical Empyrean. Cu X-ray tube. Primary beam monochromator (CuKa1).
15-position sample changer. X'celerator RTMS detector.

Both diffractometers are operated in reflection, Bragg Brentano,Theta -2Theta mode. Data collected at room temperature. Generic sample holders or PANalytical holders with 0-background Si substrate and optional Kapton film cover. Maximum 17 samplles/day. Data collection with Adjustable Divergence Slit.Operated by authorised personnel only.

STOE STADIP. Mo X-ray tube. Primary beam monochromator (MoKa1).
Single position-sensitive Mythen linear detector.

Both diffractometers are operated in capillary Debye-Scherrer mode. Data on GEORGE collected only at room temperature. RINGO is equipped with permanently mounted Cobra Plus non-liquid-nitrogen cryostream from Oxford Cryosystems for VT measurements in the range 80 -500K and STOE HT2 reaction chamber for measurements at up to 1800K with a gas flow through capillary.
