Robert E Vest (Fed)

Mr. Vest graduated from Brown University in 1991 with a Sc.B in physics. While at Brown, he worked on superconducting edge bolometers for use in solar neutrino detectors. During this time, he also worked on the NIST racetrack microtron and free electron laser project as a control system designer and computer programmer.

He came on staff at NIST in 1991 in the far and extreme ultraviolet detector program, making calibration measurements and performing research in the development and characterization of detectors. In 1998 he assumed the leadership of the far and extreme ultraviolet (5 nm to 255 nm) detector calibration program. He also led the near ultraviolet (200 nm to 500 nm) detector calibration program from 2011 to 2017. In 2017 he led the transition of the EUV detector calibration program to a newly commissioned synchrotron radiation beamline at SURF III. In 2018, Mr. Vest took on the leadership of the project to re-establish the deuterium lamp calibration service at SURF III, with customer calibrations resuming in 2020. He currently leads a team designing and implementing a major upgrade to the SURF III accelerator control system.

He continues to perform research in EUV radiometry techniques, technology, and applications and to provide calibration and metrology support to the UV and EUV user community. In addition to ultraviolet metrology, Mr. Vest has contributed metrology experience and expertise in laboratory automation to a broad portfolio of projects including a major upgrade of the SURF III control system, the neutron observatory, the development of primary standards for low-flow leak rates and calibrations of leak artifacts, the use of ultraviolet radiation for the disinfection of surfaces and air contaminated with bacteria and viruses, including the SARS-CoV-2 virus which causes Covid-19, and photodissociation of peptide bonds for protein sequencing.
