A year in orbit: ISS deployment tests radiation detectors for future space missions
The predawn darkness on a cool Florida night was shattered by the ignition of nine Merlin engines on a SpaceX Falcon 9 rocket. The thrust of the engines shook the ground miles away. From a distance, the rocket appeared to slowly rise above the horizon. For the cargo onboard, the launch was anything but gentle, as the ignition of liquid oxygen generated more than 1.5 million pounds of force. After the rocket had been out of sight for several minutes, the booster dramatically returned to Earth with several sonic booms in a captivating show of engineering designed to make space travel less expensive and more sustainable.

Modular stellarators offer a unique opportunity for innovative divertor target design by virtue of the discreteness of their diverted flux bundles. Well focused flux bundles leave the separatrix at discrete locations, emerging from the toroid between the coil legs and then re-enter the toroid. This paper describes a divertor target design which recovers the energy at a high temperature and prevents neutron streaming through the divertor slots.
