Warren S. Smith, interviewed by Stephen D. Rees, Jr., Part 1

Warren S. Smith, interviewed by Stephen D. Rees, Jr., Norridgewock, Maine, June 26, 1999. Smith briefly reviews his background as the son of an American World War II Veteran and English war bride, growing up in Skowhegan, Maine, knowing around age 13 that he would be entering the military after high school graduation, and enlisting in October 1962. Smith explains he attended flight school at Fort Rucker, Alabama and had to go to the library too look up where Vietnam was located when he received his orders. He talks about being assigned to the 611th Transport Company in Vung Tao, flying helicopters for special forces and troop transports, flying into combat and coming under fire, ARVN soldiers living their entire lives at war, and being assigned to UTT Helicopter Company. He discusses his “John Wayne” attitude going in before watching friends killed and being shot himself and describes his experiences in combat. Smith tells of leaving the service in 1965 but feeling restless and unsettled and returning to Vietnam as a civilian chopper pilot in 1968, one day after the start of the TET offensive. He describes getting in trouble for not writing home after his mother sought Red Cross to find out if he was alive. He speaks about his perspective on protestors, the war, and American policy.

Modeling of fuel-to-steel heat transfer in core disruptive accidents

"June 1980."Also issued as a Ph. D. thesis by the first author, MIT Dept. of Nuclear Engineering, 1980Includes bibliographical references (pages 110-111)A mathematical model for direct-contact boiling heat transfer between immiscible fluids was developed and tested experimentally. The model describes heat transfer from a hot fluid bath to an ensemble of droplets of a cooler fluid that boils as it passes through the hot fluid. The mathematical model is based on single bubble correlations for the heat transfer and a drift-flux model for the fluid dynamics. The model yields a volumetric heat transfer coefficient as a function of the initial diameter, velocity and volume fraction of the dispersed component. An experiment was constructed to boil cyclopentane droplets in water. The mathematical and experimental results agreed reasonably well. The results were applied to investigate the possibility of steel vaporization during a hypothetical core disruptive accident in a liquid metal fast breeder reactor. The model predicts that substantial steel vaporization may occur in core disruptive accidents, if the steel reaches its saturation temperature rapidly enough. The potential importance of steel vaporization is dependent on the accident scenario.Report issued under contract with the U.S. Nuclear Regulatory Commission NRC-04-77-12

Supporting Counselors-in-Training: A Toolbox for Doctoral Student Supervisors

Counselor education doctoral students are often required to supervise master-level counselors-in-training as part of their supervision internship. While practical, this arrangement places doctoral students and their supervisees in potentially compromised situations, given their lack of experience in these respective roles. This article offers a toolbox of strategies doctoral student supervisors can use to facilitate their work with counselors-in-training. These strategies address focus areas identified through prior research. Doctoral student supervisors are encouraged to use this toolbox in conjunction with the support and guidance of their faculty supervisor as they navigate clinical supervision

High temperature sensing with single material silica optical fibers

We present recent developments in high temperature sensing using single material silica optical fibers. By using a single material fiber, in this case a suspended-core fiber, we avoid effects due to dopant diffusion at high temperature. This allows the measurement of temperatures up to the dilatometric softening temperature at approximately 1300°C. We demonstrate and compare high temperature sensing in two configurations. The first exploits a small section of single material fiber spliced onto a length of conventional single mode fiber, which operates through multimode interference. The second utilizes a type II fiber Bragg grating written via femtosecond laser ablation.Stephen C. Warren-Smith, Linh V. Nguyen, Heike Ebendorff-Heidepriem, and Tanya M. Monr

Multi-axis fields boost SABRE hyperpolarization via new strategies

The inherently low signal-to-noise ratio of NMR and MRI is now being addressed by hyperpolarization methods. For example, iridium-based catalysts that reversibly bind both parahydrogen and ligands in solution can hyperpolarize protons (SABRE) or heteronuclei (X-SABRE) on a wide variety of ligands, using a complex interplay of spin dynamics and chemical exchange processes, with common signal enhancements between $10^3-10^4$. This does not approach obvious theoretical limits, and further enhancement would be valuable in many applications (such as imaging mM concentration species in vivo). Most SABRE/X-SABRE implementations require far lower fields (${\mu}T-mT$) than standard magnetic resonance (>1T), and this gives an additional degree of freedom: the ability to fully modulate fields in three dimensions. However, this has been underexplored because the standard simplifying theoretical assumptions in magnetic resonance need to be revisited. Here we take a different approach, an evolutionary strategy algorithm for numerical optimization, Multi-Axis Computer-aided HEteronuclear Transfer Enhancement for SABRE (MACHETE-SABRE). We find nonintuitive but highly efficient multi-axial pulse sequences which experimentally can produce a 10-fold improvement in polarization over continuous excitation. This approach optimizes polarization differently than traditional methods, thus gaining extra efficiency
