Meeting Overview:
The Albuquerque NCSL International Section 1324 provides about three hours of metrology related training, information and discussion. Our goal is to promote metrology, calibration, and testing throughout the region. You will meet other metrology, calibration, and testing professionals and there is plenty of time for networking.

Meeting Speakers:
Meet the FLOC-ers: Progress Toward Primary Pressure Realization Using Optical Measurements
Kevin Douglass, National Institute of Standards and Technology (NIST)

Towards the goal of quantum-based traceability of the SI, NIST has developed an optical pressure standard where traceability is achieved through accurate quantum mechanical calculations of the refractivity virial coefficients of helium.   Extremely accurate measurements of refractive index are possible and primary traceability for the Fixed Length Optical Cavity (FLOC) will require an independent approach, relying solely on refractive index.  The main issue for the FLOC is determining the pressure dependent distortion terms.  Thus, one needs to know both pressure and the pressure dependent distortion term.  The two currently most viable methods to achieve this are the two-gas and two-color methods.  Essentially providing two measurements in-order to determine two unknown variables.  I will discuss this approach and current limitations.   I will also briefly present NIST-MKS prototype FLOC system that was developed under a collaborative research and development agreement (CRADA) and demonstrated as a working unit at the AVS meeting in October 2018.

Multi-Junction Thermal Converters for AC Calibrations
Raegan Johnson, Sandia National Laboratories

Presently, no quantum or intrinsic standards are available for AC voltage or AC current calibrations. As such, AC calibrations are largely performed using a transfer standard approach with single junction thermal converters; a technology from the 1950’s. The goal of this project is to build upon a multi-junction thermal converter design developed circa 2000 by Tom Wunsch at Sandia National Laboratories. This design uses a microfabrication approach to make a chip with ~100 thermal junctions and device dimensions of a few millimeters. The proposed new device design will have wider frequency range, larger voltage range, and a more practical impedance. Thus far, devices have been fabricated at Sandia and initial measurements have been performed. These measurements show an AC-DC difference <2 ppm in the 100 Hz to 10 kHz range. Information about the fabrication process and data from the initial results will be presented. Future design needs as well as R&D being performed on a quantum AC standard, a non-commercially available Josephson Arbitrary Waveform Synthesizer (JAWS), will also be discussed.

WebEx Presentation: 3458A Technology Refresh
Phil Stearns, Keysight Technologies

Keysight has taken a proactive approach to help you upgrade your key assets like the 3458A.  The 3458A is almost 30 years old, but there is still no better technology available today.  To alleviate the fear of knowing that some of the materials used to produce the 3458A are no longer available or the latest technology, Keysight has done a technology refresh to the 3458A.  It has been updated using current SMT and RoHS compliant technology and all new boards were designed to be 100% reverse compatible to the legacy 3458A’s.  Your refreshed units will be fully sustainable with the quality and reliability of your legacy unit without the cost of new equipment.

Past Meetings and Events

Albuquerque Section Meeting, Monday June 4, 2018
The NCSL International Albuquerque Section held its summer meeting on June 4, 2018 at the Compa Industries/TEVET Albuquerque Corporate Office. The meeting lasted for approximately seven hours and had 25 attendees. The meeting was led by Dilip A. Shah of E = mc3 Solutions, who has over 40 years of industry experience in metrology, electronics,
instrumentation, measurement and computer applications of statistics in the Quality Assurance areas. The meeting host was Keysight Technologies, who provided both the meeting location and lunch for all attendees. Snacks and refreshments were provided throughout the meeting by the NCSL International Albuquerque Section leads.

Albuquerque Section Meeting, Wednesday January 10, 2018
The NCSL International Albuquerque Section held its winter meeting on January 10, 2018 at the Juan Tabo Public Library. The meeting lasted for approximately two hours and had 22 attendees. One of our speakers, Joshua Stanford was not able to attend. His presentation titled, “Gage R&R Study on New LCR Measurement System Software,” will be moved to a future NCSLI Albuquerque Section meeting. The meeting began with an announcement of upcoming NCSLI events such as the upcoming Technical Exchange in February and the Workshop & Symposium held in late August. Attendees were then encouraged to become NCSLI members, if they were not already.
