In ESA's Cosmic Vision program, the Japanese SPICA satellite is a mission of opportunity in the M-class, with the SAFARI instrument being one of the next generation space-borne astronomy instruments being developed to take advantage of SPICA’s cryogenically cooled 3-m class primary mirror. The SAFARI instrument will use large-format arrays of Transition Edge Sensor (TES) bolometers read-out with ...
The Effect of Space Charge due to the Auto-Ionization of Neutral, Hydrogenic States in Point-Contact Germanium Detectors at MilliKelvin Temperatures - new

A class of semiconducting detectors, operated at temperature T~50mK, has direct application to the search for dark matter particle, when are able to simultaneously measure both the ionization and phonons created by particle interactions. We explore the effect of space charge accumulation in a germanium p-type point contact detector which arises due to the auto-ionization of hydrogenic ...

Since 2011, LATMOS has been involved in the development of Micro-ARES, an electric field sensor forming part of the DREAMS science payload of the ExoMars 2016 Schiaparelli entry, descent and landing demonstrator module (EDM). Micro-ARES is dedicated to the very first measurement and characterization of Martian atmospheric electricity. The instrument, a compact version of the ARES instrument ...

An interaction of aluminum aircraft skins with a laboratory-simulated, low-level, long-duration, continuing current representative of a natural lightning flash was modeled with COMSOL Multiphysics. For the analysis of the lightning direct effects on aircraft, the external environment is represented by the idealized current components. Particularly Component C is used and is characteristic of ...

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission ...

Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML controller. A single electromagnet AML was modeled and simulated with COMSOL Multiphysics. The modeling and ...
Numerical Optimization of Heating for High-Speed Rotating Cup by Means of Multiphysics Modeling and its Experimental Verification - new

The physics of rotating cups and disks is an important research subject in many areas of engineering. The rotating cup/disk has been employed in many industrial applications such as spin-coating of phosphor on television screens or photoresist films on silicon wafer, concentrating solutions by evaporation, centrifugal atomization of metal melts, and glass flakes production. In this work the ...

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded with currents up to 400 kA. For this purpose, a test rig containing a high-voltage pulsed power supply and high ...

Probing ultrafast processes over subpicosecond and picosecond time scales provides fundamental insight into the nature of materials. We have experimentally demonstrated terahertz (THz)-pulse-induced tunneling in a scanning tunneling microscope (THz-STM) to image surfaces with simultaneous nanometer spatial resolution and subpicosecond time resolution . However, the exact mechanism by which ...

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. This work presents a robust approach to the design of EM Shielding based on Graphene (Gph) layers. It is a two ...
