International Workshop on Breakdown Science and High Gradient Technology (HG2013)

3 Jun 2013, 08:00 → 6 Jun 2013, 18:00 Europe/Rome

ICTP Trieste

Gerardo D'Auria (Elettra Trieste), Sami Tantawi (SLAC), Toshiyasu Higo (KEK), Walter Wuensch (CERN)

The seventh annual workshop on high gradients, HG2013, will be hosted this year by the Sincrotrone Trieste. High-gradient RF is now being considered for a wide variety of accelerator applications and the objective of this workshop is to advance the field by bringing together our research and development community. The workshop will cover experiments, simulations, technology and theory in a format similar to past years. The web pages of last year's workshop, hosted by KEK, can be found at https://indico.cern.ch/conferenceDisplay.py?ovw=True&confId=165513. The organizing committee: Gerardo D'Auria, Sincrotrone Trieste Toshi Higo, KEK Sami Tantawi, SLAC Walter Wuensch, CERN
