Abstract New developments in liquid scintillators, high-efficiency, fast photon detectors, and chromatic sorting have opened up the possibility for building a large-scale detector that can discriminate between Cherenkov scintillation signals. Such could reconstruct particle direction species using light while also having excellent energy resolution low threshold of scintillator detector. Situated deep underground, utilizing new techniques computing reconstruction, this achieve unprecedented...
Significant advances in microwave and millimeter wave technology over the past decade have enabled development of a new generation imaging diagnostics for current envisioned magnetic fusion devices. Prominent among these are electron cyclotron emission imaging, phase interferometers, scattering, reflectometer systems Te ne fluctuations (both turbulent coherent) profiles (including transport barriers) on toroidal devices such as tokamaks, spherical tori, stellarators. The diagnostic is...
Diagnostic systems for fluctuation measurements in plasmas are, of necessity, evolving from simple one-dimensional (1D) to multidimensional due the complexity magnetohydrodynamics (MHD) and turbulence physics as illustrated by advanced numerical simulations. Using recent significant advancements millimeter wave imaging technology, microwave reflectometry (MIR) electron cyclotron emission (ECEI), simultaneously measuring density temperature fluctuations, have been developed Toroidal...

Understanding the behavior of fluctuations in magnetically confined plasmas is essential to advancement turbulence-based transport physics. Though microwave reflectometry has proven be an extremely useful and sensitive tool for measuring small density some circumstances, this technique been shown have limited viability large amplitude, high kθ and/or core measurements. To end, a new instrument based on two-dimensional imaging developed measure over extended plasma region TEXTOR tokamak. This...
To investigate the direct effect of leukocyte adherence to microvessel walls on permeability, we developed a method measure changes in hydraulic conductivity ( L p ) before and after adhesion individually perfused venular microvessels frog mesentery.

The neutron polarization asymmetry in neutron-deuteron scattering has been measured from 44.5\ifmmode^\circ\else\textdegree\fi{} to 160\ifmmode^\circ\else\textdegree\fi{} (c.m.) angle. results display quantitatively the same structure as proton-deuteron data, but discrepancies appear for angles corresponding those near minimum of differential cross section. In this region is considerably more negative than case, and both are current theoretical predictions.
