Picometer Metrology for Precise Measurement of Refractive Index, Pressure, and Temperature

December 18, 2013
Author(s)
Jack A. Stone Jr., Patrick F. Egan, Donavon Gerty, Jay H. Hendricks, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace, Gregory F. Strouse
Fabry-Perot interferometers can be used for very precise measurement of the refractive index of gasses. This can enable increased accuracy of interferometer-based length measurement. In addition, because the refractive index of a gas depends on its

Picometer metrology for precise measurement of refractive index, pressure, and temperature

July 14, 2013
Author(s)
Jack A. Stone Jr., Patrick F. Egan, Jay H. Hendricks, Gregory F. Strouse, Douglas A. Olson, Jacob E. Ricker, Gregory E. Scace
For several years we have been studying the use of Fabry-Perot interferometers for precise measurement of the refractive index of gasses, where the primary motivation has been to improve interferometer-based length measurement. Because the refractive index

Faster, Better, Cheaper: New Automated Vacuum Calibration Service at NIST

October 1, 2012
Author(s)
Jacob E. Ricker, Jay H. Hendricks, Douglas A. Olson, Gregory F. Strouse
In today’s fast-paced world and ever expanding quality assurance requirements, the National Institute of Standards and Technology (NIST) has developed a system to fill the need for faster, better, and cheaper low pressure calibrations (0.65 Pa to 130 kPa)

Towards portable vacuum standards

August 1, 2009
Author(s)
Jay H. Hendricks, Douglas A. Olson
Since the middle of the 17th century, when Italian physicist Evangelista Torricelli discovered that a glass tube filled with mercury could be used to measure atmospheric pressure, liquid-column manometers have been used as a primary standard to measure

Effect of Dissolved Nitrogen Gas on the Density of Di-2-Ethylhexyl Sebacate: Working Fluid of the NIST Oil Ultrasonic Interferometer Manometer Pressure Standard

June 1, 2009
Author(s)
Jay H. Hendricks, Jacob R. Ricker, Justin H. Chow, Douglas A. Olson
The National Institute of Standards and Technology (NIST) Low Pressure Manometry Laboratory maintains national pressure standards ranging from 1 mPa to 360 kPa through the operation of four ultrasonic interferometer manometer (UIM) pressure standards. NIST

Quantitative Measurement of Outgas Products From EUV Photoresists

March 14, 2008
Author(s)
Charles S. Tarrio, Bruce A. Benner Jr, Robert E. Vest, Steven E. Grantham, Shannon B. Hill, Thomas B. Lucatorto, Jay H. Hendricks, Patrick J. Abbott, Greg Denbeaux, Alin Antohe, Chimaobi Mbanaso, Kevin Orbek
The photon-stimulated emission of organic molecules from the photoresist during exposure is a serious problem for extreme- ultraviolet lithography (EUVL) because the adsorption of the outgassing products on the EUV optics can lead to carbonization and

A Low Differential-Pressure Primary Standard for the Range 1 Pa to 13 kPa

December 1, 2005
Author(s)
A P. Miiller, Charles R. Tilford, Jay H. Hendricks
The National Institute of Standards and Technology (NIST) has completed the development of a low differential-pressure primary standard covering a range from 1 Pa to 13 kPa for operation with line pressures up to 200 kPa. The standard is based on a UIM

In Situ Raman Spectroscopic Investigation of Stainless Steel Hydrothermal Corrosion

September 1, 2002
Author(s)
James E. Maslar, Wilbur S. Hurst, Walter J. Bowers Jr., Jay H. Hendricks
In situ Raman spectroscopy was employed to investigate corrosion of 304L stainless steel in air-saturated water at a pressure of 25.2 Mpa and temperatures up to 496 C in an optically accessible flow cell. The steel also was characterized ex situ with Raman

In Situ Raman Spectroscopic Investigation of Nickel Hydrothermal Corrosion

March 1, 2002
Author(s)
James E. Maslar, Wilbur S. Hurst, Walter J. Bowers Jr., Jay H. Hendricks, M I. Aquino
A nickel coupon was exposed to air-saturated water at a pressure of 25.4 MPa and temperatures ranging from 21 C to 460 C in an optically accessible flow cell. In situ Raman spectra were collected at a number of temperatures as the coupon was heated and

In Situ Raman Spectroscopic Investigation of Chromium Surfaces Under Hydrothermal Conditions

August 1, 2001
Author(s)
James E. Maslar, Wilbur S. Hurst, Walter J. Bowers Jr., Jay H. Hendricks, M I. Aquino, Igor Levin
Three chromium coupons were exposed to air-saturated water at pressures of ca. 25 MPa and temperatures up to 545 C in an optically accessible flow cell. In situ Raman spectra were collected at different temperatures as the coupons were heated and then
