Future application of linac in science and environment

Particle accelerator has been driven by high energy physics for decades. However, with the energy demand for future collider becomes higher (eg, ILC of 3TeV SRF linac), the cost for a future collider has been extensively pushed. Advanced accelerating technologies are being developed to reduce the cost for future colliders. Based on the achievements of R&D on future collider, there are many ongoing projects, such like LCLSII, FRIB, ADS in China and so on. In the talk, I’ll review the current R&D front of RF linac and its applications in science and environment in future.
