  During the past century particle accelerators and their technology have played an essential role to improve standards of living and well-being. Originally developed to investigate the fundamental laws of nature, today, accelerators in different configurations are producing beams of subatomic particles and charged atoms that help to manage our health and our environment; they also provide a significant tool for manufacturing industry, for sustaining greener, safer energy, and for securing our borders and ensuring national security. They offer advance investigation methods considered essential in many fields of basic and applied science. Innovative technical developments are in progress or in the horizon, and will extend the practical use of accelerators even further for the social and economic benefit of all. The quest for more compact, more efficient, lower cost, portable, combined with imaging,… is ongoing and not absent of challenges. In this talk the recent developments of particle accelerators focused in societal applications will be described as well as the issues, challenges and opportunities the R&D in this brave new field is facing.

  The PRAE (Platform for Research and Applications with Electrons) accelerator is being built at Orsay campus with the main objective of creating a multidisciplinary R&D platform, involving subatomic physics, instrumentation, radiobiology and clinical research around a high-performance electron accelerator with beam energies up to 70 MeV (planned 140 MeV). In this paper we will report the optics design and beam dynamics simulations for the beam line dedicated to subatomic physics, more specifically for the measurement of the proton radius. This measurement requires extremely low energy spread (5×10−4) and small beam sizes with low divergence at three beam energies: 30, 50 and 70 MeV. The beam line includes a D-type chicane coupled to a dechirping passive structure, which generates inductive wakefields in order to get the performances required for such measurement.

  The ultrafast electron microscope provides a useful tool for exploring fine structure and observing dynamic process at nanometer and picosecond scale, which has been extensively applied in chemistry and biological field. After emitting from the electron gun, electron beams are focused on the stage sample by the condenser system and then be projected by the imaging system on the screen. In the present study, a two-lens condenser system is simulated by Parmela and a three-lens imaging system is designed using thin-lens approximation. Besides, the shape factor of metallic spheres which have different radius for perturbation method is measured, which is conductive to measuring the Z/Q parameter and the electric field along the axis of the C-band 3MeV photocathode gun for the UEM.

  High energy electron imaging, an extension of conventional transmission electron microscopy, is suitable for imaging of thicker objects and expected to be a promising tool for diagnostics of high energy density physics (HEDP). A cascade high energy electron imaging system using two-stage imaging lenses based on strong permanent magnet quadrupoles is designed, optimized and finally installed at Tsinghua university. Encouraging result of 1.6-μm space resolution is obtained in our primary experiments, along with the clear imaging of a spherical capsule as a substitute of the targets used in inertial confinement fusion. Successful implement of cascade high energy electron imaging system is necessary for reaching better resolving power of the imaging system, and well matching of design, simulation with experimental results paves the way to high energy electron microscopy to provide full capacities for diagnostics of HEDP with sub-um and picosecond spatiotemporal resolutions.
