Micromachines, 2019 In this report, we propose a micro vacuum chuck (MVC) which can connect three-dimensional (3D) tissues to a tensile test system by vacuum pressure. Because the MVC fixes the 3D tissue by vacuum pressure generated on multiple vacuum holes, it is expected ...

Equilibrium and perturbations in plasma-vacuum systems [PDF]
, 1975 High temperature plasmas of toroidal forms necessary to obtain fusion reactions between light elements (thermonuclear fusion) must be maintained far from all material contact. In order to realise this condition one uses, in the vacuum surrounding the plasma, a metal wall supposed perfectly conducting and currents I. whose positions and intensities have

Study on Optimization Matching of Catcher and Vacuum pump in Vacuum cooling
Zhileng xuebao, 2006 The matching of the catcher and the vacuum pump determines the pre-cooling quality during vacuum cooling processes.With the assumption of the water vapor resulted from the vacuum cooling to be ideal gas,the energy consumptions of the catcher and the ...

Journal of Physics: Conference Series, 2012 Vacuum technology is an integral part of any accelerator system. At IUAC we have a 15UD PELLETRON, superconduting LINAC, Low Energy Ion beam Facility and a 1.7MV pelletron. Vacuum requirement in these accelerators is ~10−8 torr. Various types of Vacuum pump are used in different zones of the accelerators depending on load.
