Active dosimetry for VHEE FLASH radiotherapy using beam profile monitors and charge measurements / Rieker, Vilde F (CERN ; Oslo U.) ; Corsini, Roberto (CERN) ; Stapnes, Steinar (CERN) ; Adli, Erik (Oslo U.) ; Farabolini, Wilfrid (CERN) ; Grilj, Veljko (SUBATECH, Nantes) ; Sjobak, Kyrre N (Oslo U.) ; Wroe, Laurence M (CERN) ; Aksoy, Avni (CERN ; Ankara U.) ; Robertson, Cameron S (Oxford U.) et al.
The discovery of the FLASH effect has revealed a high potential for treating cancer more efficiently by sparing healthy tissue. The surge in related medical research activities over the last couple of years has triggered a demand for technology with the capability of generating and measuring ionizing radiation at ultra-high doserates (UHDR).

Plastic Scintillator Dosimetry of Ultrahigh Dose-Rate 200 MeV Electrons at CLEAR / Hart, Alexander (Victoria U.) ; Giguère, Cloé (Laval U.) ; Bateman, Joseph (Oxford U.) ; Korysko, Pierre (Oxford U.) ; Farabolini, Wilfrid (CERN) ; Rieker, Vilde (CERN ; Oslo U.) ; Esplen, Nolan (Victoria U.) ; Corsini, Roberto (CERN) ; Dosanjh, Manjit (Oxford U.) ; Beaulieu, Luc (Laval U.) et al.
Very-high-energy electron (VHEE) beams with energies greater than 100 MeV may be promising candidates for FLASH radiotherapy due to their favorable dose distributions and accessibility of ultrahigh dose rates (UHDRs). Combining VHEE with the normal tissue-sparing FLASH effect of UHDR radiotherapy could improve patient outcomes. [...]

Real-time Plastic Scintillation Dosimetry of Ultra-High Dose Rate Very High Energy Electrons (VHEE) at CERN CLEAR Facility / Giguère, Cloé (Laval U.) ; Hart, Alexander (Victoria U.) ; Bateman, Joseph (Oxford U.) ; Korysko, Pierre (Oxford U. ; CERN) ; Farabolini, Wilfrid (CERN) ; LeChasseur, Yoan (McGill U.) ; Bazalova-Carter, Magdalena (Victoria U.) ; Beaulieu, Luc (Laval U.)
Very High Energy Electrons (VHEE) that can theoretically treat deep-seated tumours and be delivered at ultra-high dose rates (UHDR) could be the solution to translate FLASH radiotherapy into the clinic. Standard dosimeters have limited application in those extreme conditions, but dose-rate independent and fast-response plastic scintillation detectors (PSDs) are a potential alternative to overcome this.

Methods for VHEE/FLASH Radiotherapy Studies and High Dose Rate Dosimetry at the CLEAR User Facility / Korysko, Pierre (U. Oxford (main) ; CERN) ; Bateman, Joseph (U. Oxford (main) ; CERN) ; Corsini, Roberto (CERN) ; Dyks, Luke (CERN) ; Farabolini, Wilfrid (CERN) ; Rieker, Vilde (CERN) ; Robertson, Cameron (U. Oxford (main) ; CERN)
The CERN Linear Electron Accelerator for Research (CLEAR), operating since 2017, is a user facility providing electron beams for a varied and large range of experiments. The accelerator can generate a 60-220 MeV electron beam and it was recently selected to study the feasibility of using Very High Energy Electrons (VHEE) at Ultra High Dose Rate (UHDR) for cancer radiotherapy.

VHEE FLASH sparing effect measured at CLEAR, CERN with DNA damage of pBR322 plasmid as a biological endpoint / Wanstall, Hannah C (Manchester U. ; Daresbury) ; Korysko, Pierre (Oxford U. ; CERN) ; Farabolini, Wilfred (CERN) ; Corsini, Roberto (CERN) ; Bateman, Joseph J (Oxford U., Theor.

Ultra-high dose rate (UHDR) irradiation has been shown to have a sparing effect on healthy tissue, an effect known as ‘FLASH’. This effect has been studied across several radiation modalities, including photons, protons and clinical energy electrons, however, very little data is available for the effect of FLASH with Very High Energy Electrons (VHEE).

VHEE High Dose Rate Dosimetry Studies in CLEAR / Rieker, Vilde (CERN) ; Bateman, Joseph (JAI, UK ; CERN) ; Corsini, Roberto (CERN) ; Dyks, Luke (CERN ; Oxford U.) ; Farabolini, Wilfrid (IRFU, Saclay) ; Korysko, Pierre (Oxford U. ; CERN)
The 200 MeV electron beam of the CERN Linear Accelerator for Research (CLEAR) user facility at CERN has been intensively used to study the potential use of Very High Energy Electrons (VHEE) in cancer radiotherapy. In particular, irradiation tests have been performed in the high dose rate regime, which has gained a lot of interest for the so called FLASH biological effect, in which cancer cells are damaged while healthy tissue is largely spared.

CERN-based experiments and Monte-Carlo studies on focused dose delivery with very high energy electron (VHEE) beams for radiotherapy applications / Whitmore, L (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech. ; Texas U., Houston) ; Mackay, R I (Manchester U.) ; van Herk, M (Manchester U.) ; Korysko, P (Oxford U. ; CERN) ; Farabolini, W (CERN) ; Malyzhenkov, A (CERN) ; Corsini, R (CERN) ; Jones, R M (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.)
Very High Energy Electron (VHEE) beams are a promising alternative to conventional radiotherapy due to their highly penetrating nature and their applicability as a modality for FLASH (ultra-high dose-rate) radiotherapy. The dose distributions due to VHEE need to be optimised; one option is through the use of quadrupole magnets to focus the beam, reducing the dose to healthy tissue and allowing for targeted dose delivery at conventional or FLASH dose-rates.
