Daniel Jardin (Fed)

Dr. Dan Jardin is a physicist at the National Institute of Science and Technology (NIST) > Physical Measurement Laboratory > Radiation Physics Division > Neutron Physics Group. His primary focus is on neutron meter calibration for personnel protection and dosimetry. In addition to his calibration work, he is interested in detector development and neutron spectroscopy. One project he is involved with utilizes cryogenic Thermal Kinetic Inductance Detectors (TKIDs) to measure charged particles to study the properties of beta decay. Another project uses gas-phase scintillation detectors in a modular array to measure neutron spectra, with the possible application of locating water on the Moon.

Dr. Jardin received a B.S. in Physics with a minor in Mathematics from Syracuse University and a Ph.D in Physics from Southern Methodist University. During that time, he was a member of the SuperCDMS collaboration hunting for dark matter with cryogenic Transition-Edge Sensors (TESs) deep underground. His specialty was the measurement and mitigation of radon backgrounds, and data analysis. After graduation, he worked as a Postdoctoral Scholar at Northwestern University on the Micro-X project and was part of the first group to successfully operate TESs in space. Micro-X is a NASA-funded sounding rocket designed to record a high-resolution x-ray spectrum of the supernova remnant, Cassiopeia A.
