Item type:Publication, Access status: with files , In-situ testing of a multi-band software-defined radio platform in a mixed-field irradiation environment(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-24); ; ; ; This paper presents an in-situ test concept for a multi-band software-defined radio (SDR) platform in a mixed-field radiation environment. Special focus is given to the complex automated test setup with respect to the requirements of the irradiation facility. Additionally, selected test results of a system-level evaluation are presented and discussed. For the verification of the mixed-field radiation environment, the software-defined radio (SDR) was also tested under proton irradiation. The cross-sections for the observed single event effects are compared and show similar results.Publicationtype: Journal Article150 224 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Circuit design for a radiation tolerant 2.4 GHz synthesizer based on COTS components(2018-03-09); ; ; ; This paper presents a radiation tolerant integer-N phase-locked loop synthesizer based on commercial off-the-shelf components. The circuit features a tuning range from 2.24 GHz to 2.45 GHz and a phase noise of -82 dBc/Hz at 1 kHz offset. System level irradiation testing is conducted using high energy mixed-field radiation. First tests show excellent long-term stability of the circuit with no significant degradation up to an 1 MeV equivalent fluence of 8E+11cm-2.Publicationtype: Conference Paper95 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , In-containment signal conditioning and transmission via power lines within high dose rate areas of nuclear power plantsSignal conditioning and transmission for sensor systems and networks within the containment of nuclear power plants (NPPs) still poses a challenge to engineers, particularly in the case of equipment upgrades for existing plants, temporary measurements, decommissioning of plants, but also for new builds. This paper presents an innovative method for efficient and cost-effective instrumentation within high dose rate areas inside the containment. A transmitter-receiver topology is proposed that allows simultaneous, unidirectional point-to-point transmission of multiple sensor signals by superimposing them on existing AC or DC power supply cables using power line communication (PLC) technology. Thereby the need for costly installation of additional cables and containment penetrations is eliminated. Based on commercial off-the-shelf (COTS) electronic parts, a radiation hard transmitter is designed to operate in harsh environment within the containment during full plant operation. Hardware modularity of the transmitter allows application specific tradeoffs between redundancy and channel bandwidth. At receiver side in non-radiated areas, signals are extracted from the power line, demodulated, and provided either in analog or digital output format. Laboratory qualification tests and field test results within a boiling water reactor (BWR) are validating the proof of concept of the proposed system.Publicationtype: Conference Paper397 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , A high performance line filter for narrowband power line communication testbed applications(2013-10); ; ; This paper is presenting a two-stage line filter design, optimized for power line communication (PLC) testbed applications in the frequency range from 9 kHz to 500 kHz. The filter shows a very high differential mode attenuation together with a high input impedance on load-side. It enables to cope with the harsh noise characteristics of the PLC channel, as well as varying line access impedances in order to build up testbeds without any additional equipment. After exploring the filter's architecture, SPICE simulations and measurement results are carried out, while the latter are discussed with respect to two commercial off-the-shelf filters.Publicationtype: Conference Paper103
