Radiation Absorbing Materials (RAM) but are also important in applications where the material sample to be measured does not undergo major interventions. They consist of evaluating a received signal resulting from a free-space transmission through two horn antennas with beam collimating lenses and a Vector Network Analyzer (VNA). The characteristics of the transmitted signal are modified by a material positioned between the transmitting and receiving antennas. This work presents methods for electromagnetic characterization in Free Space, in the frequency range of 8.2 to 12.4 GHz (X-Band), in a semi-anechoic chamber, seeking the development of measurement processes that present results with repeatability and reliability. The measurements were made with standard and electromagnetic radiation absorbing materials. The measurement technique presented 95% of efficiency.

I'll be a speaker at GB-RADNEXT (12-13 June, 2024), sharing some of my experiences helping New #Space companies with #radiation topics, the talk is titled “𝗪𝗵𝗮𝘁 𝗡𝗲𝘄 𝗦𝗽𝗮𝗰𝗲 𝘄𝗮𝗻𝘁𝘀 𝗳𝗿𝗼𝗺 𝗿𝗮𝗱𝗶𝗮𝘁𝗶𝗼𝗻 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 𝗳𝗮𝗰𝗶𝗹𝗶𝘁𝗶𝗲𝘀” abstract below: "New Space companies vary in radiation testing approaches. New ventures prioritise rapid deployment and initial operation phases to secure further funding, while mature companies face customer demands for some level of radiation risk mitigation without the full cost of a 'rad hard' approach. There is frustration over the high costs, resource demands, and lack of clear guidelines for short-term missions or less intensive testing options. Companies seek affordable, fast testing facilities with broad capabilities, favoring local options. Future desires include easier access to heavy ion testing, guidance for companies with higher radiation risk tolerance, and standards for both board level and alternative testing methods." 📝  The workshop is free and you can register at: https://lnkd.in/e65z9Yf3 RADNEXT is a European infrastructure project with the objective of creating a network of facilities and related irradiation methodology for responding to the emerging needs of electronics component and system irradiation; as well as combining different irradiation and simulation techniques for optimizing the radiation hardness assurance for systems, focusing on the related risk assessment.

As our last post describing the CALIBRATION LIFE CYCLE prior to the 4S Symposium on Small Satellite Systems and Service https://lnkd.in/eDEBVMJe next week in Mallorca Spain, we discuss the next phase: Vicarious Calibration. Ever wonder how satellite data reflects ground truth? Vicarious calibration is a key element and Labsphere’s FLARE network takes it to the next level by creating point sources of radiation on the ground. FLARE (Field, Line-of-sight Automated Radiance Exposure) comprises ground-based mirror array systems in worldwide locations, providing crucial reference measurements for validating and calibrating satellite radiometric and geometric observations. This system allows automated “looks” at the calibrated mirrors which track the satellite and provide a known incident spectral radiance at the satellite imager during scheduled flyovers. This method allows for absolute radiometric calibration, point spread function(PSF) analysis, georeferencing, and BRDF analysis of the local region. This collaboration ensures your satellite data is not just accurate, but also reliably calibrated to real-world conditions and any changing response of the on-board instruments. Be sure to stop by at #4SSymposium2024 to discuss your application in detail at Stand 12 with Labsphere, Inc. #VicariousCalibration #SatelliteData #GroundTruth #FLARENetwork

The UAE has introduced an official time reference clock powered by a cesium atomic clock, setting a new standard for precise time measurement in the region. This advanced cesium By implementing this clock, the UAE aims to ensure precise and consistent timekeeping, which is essential for industries such as telecommunications, navigation, and scientific research. The clock’s accuracy plays a critical role in enhancing these fields by providing a reliable time standard. The Emirates Metrology Institute (EMI) is at the forefront of this initiative, contributing to International Atomic Time (TAI) and refining Coordinated Universal Time (UTC) within the UAE. EMI also maintains the UAE’s sole time standard linked to UTC, offering time synchronization services and reducing the risks of interference from satellite systems. Saeed Al Mheiri, Executive Director of EMI, highlighted that this launch is a strategic move toward enhancing time measurement accuracy. It supports the UAE’s broader goals of innovation and leadership in global quality standards. . . . #UAETime #AtomicClock #PrecisionTimekeeping #Innovation #EmiratesMetrologyInstitute #Tribunetrends

This week, we're zooming in on the Equivalent LET Module of our OMERE software!   What is OMERE? 🛰️   OMERE is a free software developed by TRAD, Tests & Radiations with the support of CNES. OMERE calculates the space environment in terms of particle fluxes and radiation effects on electronic devices, including dose, displacement damage, single event effects, and solar cell degradation. Developed for industrial needs for more than 20 years now, and used daily by space Agencies and key industrial players all around the world, OMERE is an efficient tool that enables easy and accurate radiation analyses.   Our OMERE solution comes with an Equivalent LET Module. 👇   This Equivalent LET Module enables users to evaluate the LET deposited in a sensitive volume behind layers of Silicon, SiO2, Aluminum or Copper. The thickness of these different layers can be defined to reproduce the internal structure above the sensitive volume to anticipate the sample preparation and allow an efficient irradiation with expected LETs for SEE characterization.   👉 Download OMERE for free at https://lnkd.in/ePpAK7SX 👉 Contact us for more information at [email protected]   #OMERE #RadiationTesting #SpaceInnovation

Why is it Called #Fiber #Optic #Gyroscope? more details：https://lnkd.in/g9vfQ7ha Like ring laser gyro, fiber optic gyro has the advantages of no mechanical moving parts, no preheating time, insensitive acceleration, wide dynamic range, digital output and small size. In addition, fiber optic gyro also overcomes the fatal shortcomings of ring laser gyro such as high cost and blocking phenomenon. Fiber optic gyro is a kind of optical fiber sensor used in inertial navigation. Because it has no moving parts - high-speed rotor, called solid state gyroscope. This new all-solid gyroscope will become the leading product in the future and has a wide range of development prospects and application prospects.

It's finally here!! This guide was a beast to create, but—while I might be biased—I think it's a tool the #appliedmarinescience industry needed. Created with utility in mind, the marine instruments buyers' guide (MIBG) can be used widely across so many audiences. Starting a sensor or observation network, but not sure what your options are? The MIBG is a great starting point. Need a resource for marine sensor and instrument market research? The MIBG might have the answers. Are you a nerd like me who just wants to see what's newly available? The MIBG is for you. I'm excited to add to and evolve this guide. It doesn't end here. Outside of the guide itself, ECO Magazine is also focussing on improving our coverage and resources available to #marineinstrument users. You can check that out here: https://lnkd.in/eARyejuN This was entirely a team effort, but a quick shout out to Jenna Holleran who, I think, deserves an honorary degree in marine sensors and instruments. You fully took on this challenge and tackled it with grace. And thank you Keith Meinhold for translating the ideas locked in my head into a unique, exclusive, and graphically pleasing product.

With CMTDA1, Cryogenic Differential Amplifier, Cosmic Microwave Technology, Inc. has been developing cryogenic, low noise differential amplifiers primarily for integration with Superconducting Nanowire Single Photon Detectors (SNSPD). The structure of the SNSPD consists of a meandering line embedded on a super-conducting material that is cooled to 1K. The meandering line structure is inherently differential. As a photon strikes the SNSPD, both a positive and negative spike is generated. The differential amplifier allows detection of both pulses. https://lnkd.in/g7BbtyaX
