Abstract The plasma diagnostics presented in this article target the plasma surrounding a spacecraft that is created by the electric thruster and its surface modifying effects. The diagnostic package includes a retarding potential analyzer, a plane L

Publikováno v: International Conference on Space Optics — ICSO 2006.

Within ESA’s Innovation Triangle Initiative (ITI) a demonstrator breadboard for a micro-ranging-laser device “MYLRAD” has been developed. Its working principle is the measurement of the round-trip delay time of a laser beam as a phase shift. Th

In aseptic filling systems, hydrogen peroxide vapour is commonly used for the reduction of microbial contaminations in carton packages. In this process, the germicidal efficiency of the vapour depends especially on the H 2 O 2 concentration. To monit

In common aseptic filling processes, hydrogen peroxide vapour is a predominantly applied antimicrobial for the inactivation of microorganisms in packages. During this process, the germicidal effectivity of the antimicrobial treatment depends especial
