Variable focusing system for neutrons

Neutrons for rafts, rafts for neutrons.

The determination of the structure of membrane rafts is a challenging issue in biology. The selection of membrane components both in the longitudinal and transverse directions plays a major role as it determines the creation of stable or tunable platforms that host interactions with components of the outer environment. We focus here on the possibility to apply neutron scattering to the study of...

Intelligent Control for the Variable-Speed Variable-Pitch Wind Energy System

In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...

Nearly diffraction-limited X-ray focusing with variable-numerical-aperture focusing optical system based on four deformable mirrors

Unlike the electrostatic and electromagnetic lenses used in electron microscopy, most X-ray focusing optical systems have fixed optical parameters with constant numerical apertures (NAs). This lack of adaptability has significantly limited application targets. In the research described herein, we developed a variable-NA X-ray focusing system based on four deformable mirrors, two sets of Kirkpat...

The “higgs” from Anti-neutrons and Neutrons

The new anti-neutron, first proposed in 2011 [16], and ordinary neutrons, are both without electric charge, and are therefore rather difficult to accelerate and/or impact together in a high energy collider sufficient to cause annihilation, and thus create a 100% energy “Higgs” styled Boson, such Bosons arguably representing all of the mass in the universe. This very high energy impact combinati...
