Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

Dear Colleagues,


Unfortunately, it has become apparent that we will need to postpone HG2020 due to the travel restrictions that have been imposed in order to prevent the rapid spread of COVID-19. We are presently evaluating options for delaying this meeting and we will reach out to you with more details soon. Any registrations that have been processed will be refunded. Please reach out with any questions or comments on this postponement. 


Wishing you and your families well during these difficult times.


All the best,

HG2020 Local Organizing Committee

Hi! We are pleased to announce the 13th workshop on breakdown science and high gradient accelerator technology, HG2020, will be held at the Granlibakken Tahoe, Tahoe City, CA on June 8-12, 2020.

Clearly the identification and advancement of high gradient accelerator technologies for a linear collider have been the main goal since the inception of the High Gradient workshop series. Historically, the workshop has heavily concentrated on progress of X-band accelerator technologies, the area in which the most recent research results have been shared and discussed. The tight collaborations among the participants have pushed practical accelerator technologies to a level that has never been achieved before. Knowledge gained through the HG workshops in the past, like the current depth in understanding RF breakdown, the procedure of fabricating and conditioning high gradient accelerators, and the novel designs of high power rf components, etc., have benefits far beyond the X-band accelerator community.

Besides the intensive focus on X-band high gradient accelerator technologies, the workshop has always made efforts to broaden the spectrum of technologies discussed and attract more talent in related fields. In recent years, the workshop has successfully recruited theorists in material science and experts in accelerator applications, whose participation has significantly enriched the program and generated mutual benefits. HG2020 will continue this journey. The workshop will share the latest advancements in, but not limited to, breakdown science, high efficiency high power RF sources, low breakdown rate high-gradient accelerators, low cost accelerator fabrication technologies, novel accelerator designs, accelerator applications to light source, medical, and industrial technologies etc. The format of HG2020 follows the format of preceding workshops, i.e. oral presentations and discussions.

We look forward to seeing you.
