Description
Laser wakefield acceleration (LWFA) is a promising approach for generating accelerating fields three orders of magnitude larger than what is currently achieved in standard RF cavities. Spectacular progress has been made during the last 15 years in understanding the physics involved in laser-plasma accelerators. The transition from demonstration experiments to accelerator beamline is observed in many high-intensity laser labs [1]. In this context at IJClab, the PALLAS (Prototyping Accelerator based on Laser-Plasma technology) project [2] aims to build a demonstrator of laser-plasma injector operating at 10Hz delivering an electron beam of 200 MeV, >30 pC, 1 mm.mrad emittance, an energy spread < 5%, and a bunch length in the femtosecond range with stability and reliability comparable to conventional RF electron accelerator. To this end, we focus on three particular areas of accelerator development: control of the laser driver, plasma target and complete characterisation of the electron bunch phase space. We will report on the progress in developing a complete control and acquisition system under Tango for the accelerator [3], incorporating a 50TW Amplitude laser driver. We will discuss the challenges of implementing the Tango control system.
