Summary, Etc.  

요약Positron acceleration in plasma is a topic of interest for future applications of plasma-based linear colliders. At the Facility for Advanced Accelerator Experimental Tests (FACET), located at SLAC National Accelerator Laboratory, we investigated the acceleration of positrons in plasma under various regimes, including linear, non-linear, and hollow channel configurations. Over the course of these experiments, we observed the acceleration of plasma electrons captured in a positron beam-driven wake. Although other experiments have observed the capture of electrons in an electron-driven wake, we are the first to demonstrate the simultaneous acceleration of both positrons and electrons in a plasma. After propagating through a 1.3 meter-long plasma, the positrons gained up to 7 Gev of energy while trapped electrons gained up to 13 GeV. The positron drive beam conditions were varied to determine the capture threshold of the plasma electrons. Simulations performed using OSIRIS 4.0 are in good agreement with the experiment, allowing for a detailed analysis of the capture dynamics. In future PWFA-based collider designs, we want to put as much energy as possible into the accelerated beam, and not these trapped electrons. By understanding the conditions that lead to capture, we can adjust future designs to mitigate or eliminate it.
