.: ISIT's report to DARPA on its "Superconducting Pulsed Transformer"

This Superconducting Pulsed Transformer would be an essential component of any gun launch to orbit system using superconducting quench, defined as what happens when a superconducting current suddenly goes non-superconducting. Today, when it becomes necessary to quench a superconductor, it requires quickly boiling off its liquid helium (video here).

Our innovation is to instead convert a superconducting current via a controlled quench into an electromagnetic force that propels a projectile. See a video here of how this might enable low cost Earth to space launch .

However, there is a crucial problem with this video. The narrator says that each superconducting coil would automatically quench, converting its energy into accelerating the launch vehicle. While it is true that each coil as shown in this video would automatically quench, this only would happen once, and likely would release its energy too slowly to effectively accelerate the launch vehicle.. Worse yet, researchers have found that unless a quench is carefully and SLOWLY managed, this will damage the system.

Our solution to enabling fast and repeatable quench operations is the Superconducting Pulsed Transformer which we designed under the DARPA contract "MACE Proof of Concept – Demonstrate Fundamental Physics.” See our final report below, or download it here.

    August 2021: ISIT's Dawna Coutant and Carolyn Meinel had been combating COVID-19 in IARPA's FOCUS program. We did better than the big modeling teams for the first six months of the pandemic. Then we were about even with the models until Delta arrived. Wow, what a surprise this was to most of us. See what we had forecasted for 2021 as of August 8, 2020 at Covid_forecasts_2021.html


    May 2020: ISIT's Carolyn Meinel explains how she used Natural Language Processing to forecast geopolitical questions in a webinar hosted by Basis Technology: Mirror, Mirror on the Wall -- which Country Will Rule them All?


    January 2020: The team of ISIT and KaDSci, LLC came in 4th place in IARPA's Geopolitical Forecasting Competition out of over 100 initial competitors by forecasting 305 questions within just 5 1/2 months: Details here.
