Progress in Primary Acoustic Thermometry at NIST: 273 K to 505 K

September 1, 2003
Author(s)
Gregory F. Strouse, Dana R. Defibaugh, Michael R. Moldover, Dean C. Ripple
The NIST Acoustic Thermometer determines the thermodynamic temperature by measuring the speed of sound of argon in a spherical cavity. We obtained the thermodynamic temperature of three fixed points on the Interna-tionalTemperature Scale of 1990: the

Author(s)
Michele Martin, Kalina Jordanova, Anthony Kos, Stephen E. Russek, Katy Keenan, Karl Stupic
Abstract Objective Temperature controlled T 1 and T 2 relaxation times are measured on NiCl 2 and MnCl 2 solutions from the ISMRM/NIST system phantom at low magnetic field strengths of 6.5 mT, 64 mT and 550 mT. Materials and methods The T 1 and T 2 were
