The BELLA Center has been developing the physics and technology of advanced laser plasma accelerators and their applications. This paper introduces experimental R&D work of the Center along with the main laser systems to drive accelerators. The Center’s largest activity has been the development of the laser plasma based electron accelerators for high energy physics applications, and a 10 GeV class laser plasma accelerator has been realized in the Center. Various R&D on associated technologies are discussed as well.
