A liquid xenon positron target concept

Positron targets are a critical component of future Linear Colliders. Traditional composed high-Z metals that become brittle over time due to constant bombardment by high-power electron beams. We explore the possibility liquid xenon target which is continuously refreshed and therefore not susceptible damage mechanisms traditional solid targets. Using GEANT4 simulation code, we examine performance show positron yield comparable when normalized radiation length. Additionally, observe peak energy deposition density (PEDD) threshold for higher than commonly employed metal targets, makes it an attractive, non-toxic alternative. develop parameter sets demonstration applications at FACET-II
