We are pleased to announce the 14th workshop on breakdown science and high gradient technology, HG2022, will be held virtually on Zoom from May 16-19, 2022.

The HG workshop series dedicate to the discovery and advancement of high gradient technologies for advanced beam applications to both magnificent fundamental researches and civil life. As the idea of X-band technologies was born out of the demand of compact collider, it is naturally boned with the high gradient conception and has been substantially discussed in previous HG workshops. At all times, with the participation of material science, our vision on breakdowns has been expanded to a more microscopical area. By the tight collaborations worldwide, we have climbed to peaks that no one has ever reached before: accelerators with gradients over 100 MV/m and less breakdown probability have been achieved, and the gradient limitation has been pushed to over 200 MV/m. Such achievement has pushed the application of high-gradient technologies to scientific facilities and to both electron and proton radiotherapy equipment.

In previous HG workshops, from large collider to desktop light, from room-temperature to cryogenic, from new structures to high power-sources, from horizons under microscope to simulations with enormous particles, voice of discussions rises one after another, benefits far beyond the high gradient community.

HG2022 will continue our adventures. The workshop will share the latest advancements in, but not limited to, breakdown theory, low breakdown rate high-gradient accelerators, novel structure designs, low-cost accelerator fabrication technologies, accelerator applications to light source, medical, and industrial technologies, high efficiency high power RF sources, etc. Although this workshop will be hold virtually, the format of HG2022 follows the format of preceding workshops, including oral presentations and poster sessions and discussions.

We look forward to seeing you again.
