A relativistically hot plasma, exposed to intense radiation, experiences a higher radiation pressure force compared to a cold plasma. The phenomenon known as the “Compton Rocket” was originally discovered by O'Dell.1 In O'Dell's work, the force acting on the plasma was derived using a phenomenological, test-particle approach. Energy-momentum conservation is employed to address particle–photon interaction, and the resulting force is integrated over the distribution function.

Research on plasma-based acceleration (PBA) has made great progress during the past few decades.1 Much of this effort has been motivated to build a considerably less expensive and more compact next generation linear collider (LC) or an x-ray free electron laser (XFEL). In PBA, an intense particle or laser beam is used to form a plasma wake that accelerates a second electron/positron beam that is properly loaded inside the wake.

Topics Deuterium, Heavy-ion collisions, Plasmas Understanding the interaction between magnetized ions and material surfaces is crucial in the design of magnetic fields facing target structures. The primary objective is to reduce wall material loss while simultaneously mitigating the production of impurities reintroduced into the plasma through ion sputtering.
