  20. HPCAT Upgrade - Scope

  21. HPCAT Upgrade – Phased Plan Phase 3 Phase 2 Phase 1 2013 2012 2015 2014 2016

  22. Canted Undulators in 2011 • Increased flux • Wider energy range • Enhanced time resolved studies HP Spectroscopy HP Diffraction • Enabled energy scanning capability • Increased flux • Wider energy range X-ray optics Canted into two beamlines Independent controls Increased capacity

  24. HPCAT Upgrade –Next Generation Experiments

  25. Hydrogen – An Alkali Metal? Similar to other alkali metals Metallic fluid predicted APS upgrade will enable the high P experiments on the “holy grail” hydrogen, with higher brilliance smaller focused beam size • Melt down of alkali metals at high P • A range of highly complex structures • Enhancement of quantum effects at high P • Possible metallic liquid ground state • (Guillaume et al, Nat Phys 2011 - HPCAT at APS)

  26. Self Evaluation Scientific impact: • Fundamental physics • Complexity in “simple” alkali metals • Ordering state in materials • Kondo collapse at high pressure • New chemistry • Nobel gas chemistry at high pressure • Liquid-liquid transitions • “structure-property” relations • Novel materials • Superconductivity at high pressure • Strength and deformation at high pressure • Synthesis of new materials • Earth and Planetary sciences • Spin transitions at high pressure • High pressure melting • Structures of post-perovskites ~1.5 papers/week ~23% in journals with impact factors ≥PRL ~7 theses per year ~6 highlights in media per year

  27. Self Evaluation – Cont. X-ray technique development: • Integration of high pressure device with the advanced synchrotron techniques • High pressure micro x-ray diffraction • Multiple tables for optimal performance and maximum stability • Coupled with high or low temperature capabilities • Time resolved studies with controlled strain rates and thermal rates • Advanced detectors (e.g., Pilatus) • High pressure micro x-ray spectroscopy • Pioneered in the development and the only dedicated beamline • High collimation and throughput for maximum S/N • High or low temperature capabilities
