      Plasma accelerators: make colliders affordable again 30m

      Conventional particle accelerators can accelerate particles to TeV scale, but require very large and consequently very expensive facilities to do so. Plasma acceleration, a novel accelerator technology, promises to drastically shrink future accelerator facilities—including particle colliders—by accelerating particles in the ultra-strong electric fields of a charge-density wave in a plasma. So, how do plasma accelerators work? What has been experimentally demonstrated? And, what is left to do before we have a plasma-based particle collider? These and other questions will be answered in this seminar.

      VHEE UHDR Dosimetry Studies at CLEAR 30m

      The electron beam at CERN Linear Accelerator for Research (CLEAR) is currently used to study the potential use of Very High Energy Electrons (VHEE) for FLASH radiotherapy, which relies on ultra high dose rates (UHDR). An important part of these studies revolves around the development of real-time dosimetry in a dose rate regime where conventional methods such as ionization chambers saturate. One potential approach is the use of a calibrated beam-based dosimetry method. The existing beam instrumentation provide real-time information on charge, transverse and longitudinal profiles of the pulses, as well as twiss parameters of the beam. In the context of achieving a real-time prediction of the dose deposition, these parameters must be correlated with the read-out of passive and dose-rate independent methods such as radiochromic films, which are presumed to be energy- and dose-rate independent. In this context, efforts has been made to establish reliable and systematic approaches for passive dosimetry at CLEAR.
