Research on Near Space Plasma Vacuum Environmental Simulation Technology

MATEC Web of Conferences, 2018
The operation reliability of spacecraft in orbitis affected by the interaction with space plasma, research on the space enviroment by advanced testing method is important. It is costly to carry out research and analysis with space flight.

Performance of marine clay stabilised with vacuum pressure: Based on Queensland experience

Journal of Rock Mechanics and Geotechnical Engineering, 2019
Stabilising soft marine clay and estuarine soils via vacuum preloading has become very popular in Australasia over the past decades because it is a cost-effective and time-efficient approach.

Effects of flow-responsive milking on milking performance of an automatic milking installation

JDS Communications
The objective of this study was to compare a quarter-level vacuum-control system that maintains teat-end vacuum during milking to a similar system with conventional vacuum-control technology for which teat-end vacuum is reduced as milk flowrate increases.

Vacuum system

, 1986
Shape and dimensions of the vacuum chamber of an electron storage ring are determined by the high power synchroton radiation generated by circulating beams. High energy (≥ 10 eV) photons of the electromagnetic radiation emitted by electron beam, impining on the internal wall of the vacuum chamber, create photoelectrons (on account of photoelectric ...

Development and Laboratory Testing of a Bucket Milking Machine with Flow-Controlled Vacuum, Based on an NI Data Acquisition System

Proceedings
In the present paper, the idea of regulating the vacuum level by means of a variable frequency drive (VFD) in order to control the speed of the vacuum pump of a milking system was considered.

Dust in accelerator vacuum systems [PDF]

Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 2002
Many accelerators of electron beams are susceptible to persistent beam lifetime disruptions, with correspondingly reduced performance. One distinguishes between three prevailing explanations of these disruptions: (1) trapping of positive atomic ions in the negatively charged beam; (2) trapping of small highly positively ionised micro-objects ("dust ...
