Historically particle accelerators are instrumental for high energy physics (accelerator based colliders) and photon science (accelerator based synchrotron light sources and free electron lasers). Now there is growing interest in applying accelerator technology to solve the grand challenge in probing matter at ultrafast temporal and ultrasmall spatial scales. In this paper we discuss how one can use MeV electrons produced in accelerators (e.g. photocathode rf guns) to study ultrafast dynamics at atomic scale through ultrafast electron diffraction and microscopy techniques. We will also describe the current status of ENTROPY (cENter for ulTRafast diffractiOn and microscoPY) at Shanghai Jiao Tong University (SJTU). This center is expected to provide access to new sciences by producing kHz rep-rate ultrafast and ultrabright electron beams that will give researchers unparalleled power and precision in examining the fundamental nature of matter.
