Magnetic activity features, such as faculae, spots, granulation, and flares leave an imprint in the optical spectrum of a star. Their spectroscopic signatures inform our knowledge of stellar magnetic fields, velocity flows and convection processes; they are also the main obstacle to detecting and characterising small planets orbiting Sun-like.

    Yolk–shell nanostructures have attracted tremendous research interest due to their physicochemical properties and unique morphological features stemming from a movable core within a hollow shell. The structural potential for tuning inner space is the focal point of the yolk–shell nanostructures in a way that they can solve the long-lasted problem such as volume .

The performance of four inductors utilizing these cores has been evaluated as a function of temperature from 20 C to C. All cores were wound with the same wire type and gauge to obtain equal values of inductance at room temperature.

High Flux have a series of advantages that permit to recommend these cores for applications requiring high power, high magnetic biasing by direct or alternating current at high frequencies. High Flux’s saturation magnetic flux density is T what is considerably higher than T for standard MPP cores or T for ferrite cores.

Design Considerations for High Temperature Power Inductors; NASA: Washington, DC, USA, Author: Sang Min Park, Eunsu Jang, Dongmyoung Joo, Byoung Kuk Lee. A large magnetic response is desirable in such applications as transformers and inductors.

The obvious advantages of these new materials are in high frequency applications with their high induction, high permeability and low core loss.

There are four amorphous materials that have been used in high frequency applications: SC, A,File Size: KB. However, current magnetic cores limit the operating frequency because core losses increase with frequency.

Therefore, new magnetic core materials are needed with higher resistivity (lower eddy-current losses), lower coercivity (lower hysteresis losses), and higher permeability and flux density (higher power density).

This chapter explores a W at 80 K high-frequency pulse tube cryocooler (PTC), which is developed in the Cryogenic Laboratory of the Chinese Academy of Sciences (CL/CAS). The U-shaped configuration is adopted for the pulse tube refrigerator. The Stirling-type high-frequency PTC has been developed in the CL/CAS.

Power convertor hot end temperatures would generally range from °C for RHU applications and °C for GPHS applications. Waste heat is removed from the cold end of the power convertor at temperatures ranging from °C, depending on the application, using conductive coupling to radiator panels.

A high-frequency digital counter is used to provide a coarse part of a time wave, while the use of IDELAYE2 primitives brings down the system’s resolution while keeping large Full-Scale Range.

Indeed, the minimum resolution on a -2/-3 speed grade device is 39 ps with precision below ps r.m.s. over a Full-Scale Range of ms.

At the core of ITER's neutral beam heating system is a novel high-frequency ion source that has been under development for years at the Max Planck Institute for Plasma Physics (IPP) in Garching, Germany.

In recent results that are significant for ITER, IPP's ELISE test rig has achieved the ion current required by ITER in hydrogen for 1, seconds. Radiological Sciences Dictionary tungsten and molybdenum, over a range of energies, are: Efficiency (η) Tungsten (Z 74) 20 kV 60 kV kV kV % % % %.

This process produces a very high flux of atomic N 2. Furthermore, by varying the N 2:He ratio and the radio-frequency power, it is possible to control both the flux and energy of this critical reactant. Hence, this synthetic approach provides a ready means of producing reactants that are free from impurities and that have controllable energies.

The only facility of its kind in the United States, the National High Magnetic Field Laboratory (MagLab) is the largest and highest-powered magnet lab in the world. Every year, more than a. Some facilities use SRF technology and hence provide average powers in the few 10 W to even kW regime.

Those focus on specific spectroscopy applications in solid state physics that benefit from high flux such as nearfield microscopy or studies of samples under extreme conditions e.g. high pressure or high magnetic fields.
