kedd, 10.00, KFKI Telephely, I. épület 1. emeleti TanácsteremThe Berkeley Lab 
Laser Accelerator (BELLA) Center is a laser facility dedicated for laser 
plasma acceleration (LPA) research. The PW facility provides high quality 
focused laser pulses in the range of 1019 W/cm2 intensity with controllable 
spatial distribution within the typical focus size of ~50 μm by a deformable 
mirror, exceptional beam pointing, shot-to-shot energy, intensity and pulse 
duration stability for high precision LPA experiments [1]. The thoroughly 
characterized and monitored femtosecond laser pulses are delivered into a 
radiation shielded target room for laser-plasma-driven electron and ion 
acceleration experiments, including the use of gas-jet and 
capillary-discharge-based LPAs, and thin-foil target studies. Highlights of 
recent results [2], and plans for gradual opening up the available resources 
for a broader user community in the recently established collaborative 
framework of the LaserNetUS will also be described.[1] K. Nakamura et al.,
