Gold shows a very high reflectivity in the IR range. In addition, Au (and protected Au) is more robust than Ag (and protected Ag). Therefore, Au based coatings are of high interest. Common techniques for the deposition of optical Au coatings are sput

Fraunhofer INT develops systems for on-board radiation sensing. On-board in this context means inside electronic boxes on printed circuit boards (PCB) in close proximity to radiation sensitive electronic devices. The ability to measure dose and/or pa

Radiation effects at cryogenic temperature are investigated in two radiation-tolerant Fluorine-doped single-mode fibers originating from two different manufacturers. This paper presents measurements at room temperature (297 K) and at cryogenic temper

International audience; Fiber Bragg Grating (FBG) based sensors are nowadays used for several applications, but, even if they present advantages for their incorporation into radiation environments, commercial-off-the-shelf devices cannot still be use

Radiation testing of thin optical coatings for space requires different approaches compared to bulk optical components or other material samples. In contrast to thicker samples, already particles of lower energy and thus lower range in the material w

Ionizing radiations affect installed electronics, limit equipment lifetimes and eventually alter materials both in space applications as well as high energy accelerators and physics experiments. In order to monitor radiation levels and predict equipm
