Extreme Astrophysics with Laboratory Electron-Positron Jets

Dr. Eva Los

Abstract:

The Fireball experiment is a laboratory astrophysics experiment based at the High Radiation Materials facility (HiRadMat) at CERN. Fireball is the only experiment worldwide capable of generating relativistic electron-positron plasmas, and is thus uniquely placed to study the role of pair plasmas in extreme astrophysical events such as the generation of gamma-ray bursts, fast radio bursts and the acceleration of cosmic rays. The current focus of Fireball is the study of the microphysical plasma instabilities which have been proposed as drivers of gamma-ray burst afterglows. Two groundbreaking prior campaigns generated the first laboratory relativistic pair plasma and made the first measurements of the growth rate and magnetic field strength of the oblique instability for a relativistic pair plasma. In this talk, preliminary results from the most recent campaign, Fireball 3, will be presented.
