Future prospects of accelerator science for particle physics

Future advances in understanding fundamental questions of nature require revolutionary developments in accelerator science to allow several orders of magnitude enhancements in terms of energy, intensity, faster timing, and higher resolution [1]. The challenges of the 21st century (energy, power, environment, resources, cost, and space) also play a significant role in the development of accelerator tools. In this overview article, we consider several recent developments and ideas that may become steps in addressing the challenges and which may find their way into designs of accelerator tools of the future.
