Paul Chow is a beamline scientist. He received a Ph.D. in Physics from University of Illinois and conducted research at the University of Houston.  He spent 2 years at BL12XU, the Taiwan Beamline at SPring-8, designing and commissioning a spectrometer for inelastic x-ray scattering.  Presently, he is a beamline scientist for HP-CAT at the spectroscopy station 16ID-D at the Advanced Photon Source.  His interest is in electronic excitations in metals.

Daijo Ikuta studied new technique for X-ray identification and crystal structure analysis of multiplesingle crystal phases on a glass thin section. His interest in this new technique is currently to refine this technique and to apply to unknown new minerals. With the use of synchrotron radiations and his thin-section method he examines the crystal structure of tiny and rare minerals in thin section. He joined HPCAT in July 2007. more »
