James A. Fedchak

Jim Fedchak has been with NIST since 2003.  He leads the vacuum project, which includes realizing and disseminating absolute pressures from 10-7 Pa to 30 Pa, and low gas flow from 10-12 mol/s to 10-6 mol/s.  He is directly responsible for ionization gauge calibrations and spinning rotor gauge calibrations.  Jim's knowledge of vacuum science and technology covers a variety of applications derived from his previous work experience. Previously, Jim worked with the Low-background Infrared Radiation project at NIST doing cryogenic infrared radiometry; worked in the photonics industry with New Focus Inc.; performed atomic spectroscopy at the University of Wisconsin; and developed spin-polarized targets at Argonne National Laboratory.  He has a PhD in experimental atomic and molecular physics from the College of William and Mary.  He has numerous publications in all of these fields.  Jim is a member of the Low Pressure Working Group of the CCM, and is presently a member of the AVS Vacuum Technology Division Committee.
