Description
Achieving high-precision, in situ measurements of electric fields is a critical challenge in ultrafast science and accelerator diagnostics. We are developing an approach using photoconductive sampling with micro-fabricated devices to map electron beam fields with unprecedented spatiotemporal resolution. This technique enables the first direct 3D vector field measurements of electron beams, offering valuable insights into collective effects such as coherent synchrotron radiation and other phenomena impacting beam quality. These low-cost, highly flexible devices present a pathway to enhancing our understanding of beam dynamics and reducing transient effects that degrade beam quality. The devices will be initially tested on the ultrafast x-ray beamline at LCLS, and could be adapted as a diagnostic tool across other SLAC user facilities. Beyond diagnostics, this approach will also help in advancing studies of ultrafast charge transport and unlocking new science in attosecond solid-state physics.
