        EPC Space announces family of space level qualified power transistors
        by Staff Writers
        Haverhill MA (SPX) Sep 30, 2020

        Rad Hard GaN discrete devices specifically designed for critical applications in the high reliability or commercial satellite space environments now available.

        EPC Space announced a family of Rad Hard enhancement mode power transistors spanning a range of 40 Volts to 300 Volts, and 4 Amperes to 30 Amperes. These power transistors demonstrate significant performance advantages over competitive siliconbased Rad Hard power MOSFETs. EPC Space technology produces devices that are smaller, have

        lower resistance, and have many times superior switching performance compared to silicon solutions. Critical spaceborne applications that benefit from this newly available performance include power supplies for satellites and mission equipment, light detection and ranging (lidar) for robotics and autonomous navigation and rendezvous docking, motor drives for robotics and instrumentation, and ion thrusters for satellite orientation and positioning as well as interplanetary propulsion of low-mass robotic vehicles.

        Beyond the performance improvement, these devices offer superior radiation hardness under heavy ions (SEE) and gamma radiation (TID). SEE immunity is guaranteed at the wafer level and EPC Space devices are manufactured in an AS9100D certified facility in the greater Boston area.

        "EPC Space is excited to bring the tremendous performance and reliability of GaN technology to the markets of defense and aerospace," said Bel Lazar, CEO.

        "We are able to offer designers a superior technology with significant space heritage as thousands of our Rad Hard GaN devices have been in orbit since January of 2019."

        Earth's Van Allen radiation belts double as particle accelerator
        Washington DC (UPI) Sep 10, 2020
        Electrons in the radiation belts surrounding Earth can be accelerated to extreme speeds across short distances, according to a study published Thursday in the journal Nature Communications. The Earth's magnetic field traps high energy particles - mostly from the sun - in what are known as the Van Allen radiation belts, named for the astronomer who discovered them. In 2012, NASA launched a pair of spacecraft, called the Van Allen Probes, to study the mechanics of the magnetosphere. The ... read more
