Experiments on Ionization Injection of Electrons into a Plasma Wakefield Accelerator at FACET Figure 1: A spectrometer image of two screens at the image plane of the magnetic spectrometer. The left frame shows the energy loss of the 20.35 GeV drive beam while the right frame shows both the unaffected beam charge at the initial beam energy and the accelerated beamlet at around 24 GeV. This beamlet has an energy spread of about 1% and contains about 30 pC of charge. The acceleration occurred in just 30 cm.

Collaborative Research: Experimental and Theoretical Study of the Plasma Physics of Antihydrogen Generation and Trapping NSF – PHY – 1202519 – Joel Fajans, Jonathan Wurtele, University of California - Berkeley The times and vertical (y) annihilation locations (green dots) of computer simulated antihydrogen atoms in the ALPHA trap under the assumption that gravity for antimatter is 100 times stronger than for normal matter. As can be seen by the solid black line, the average position of the annihilations tends towards the bottom of the trap, especially at late times. The experimental data (red circles) shows no such trend. From Description and first application of a new technique to measure the gravitational mass of antihydrogen, Nature Comm., 4 1785, 2013

Two-particle distribution and correlation function for a 1D dusty plasma experiment In this project, we devised an experiment that allows us to measure the quantities in the Liouville equation, for the first time. We did this by reducing the physical system so that it had only two particles, which were harmonically confined to move along one axis, and we used particles large enough to determine their positions and velocities by video imaging. This physical system is called a dusty plasma. From the measured velocities of the particles, we determined the two-particle distribution function


2. We also calculated the more common one-particle distribution function
