The proposed project therefore aims at improving the understanding, predictability and control of the accelerator-based electron beams involved in FLASH and Microbeam RT. The entry point will be to extend the research on collective effects in accelerators to cover the beam properties required for FLASH and Microbeam RT, profiting from my expertise in this field. Subsequently, this project will expand the study beyond the particle accelerator into the beam-matter interaction up to the target tissue. The influence of collective effects during the transport from the accelerator through matter onto the target, which up until now was sparsely studied, will be explored in detail. Based on these studies, the effective relation of input particle distribution to the dose distribution on target will be explored. This enables, the attempt to solve the inverse problem, i.e. determining the required input distribution for a desired dose distribution on target. First tests of targeted beam shaping will be a part of this project. With this kind of control, the outcome of the project will be a significant contribution to FLASH and Microbeam RT as well as to the general advancement of accelerator physics. +\setcounter{tocdepth}{2} \tableofcontents -\section{Research Goal and Expected Outcome} +\section{Research Goal and Expected Outcome}\label{sec:goal_outcome} % 2.2 Objectives @@ -131,7 +140,7 @@ The following four objectives are selected: \end{itemize} -These objectives will be achieved by investigating the influence of collective effects on the beam generation, beam transport, beam-matter interaction and diagnostics in novel electron radiotherapy methods with temporally and spatially structured beams.

The 2.5 GeV storage ring and synchrotron light source KARA (Karlsruhe Research Accelerator) provides short x-ray pulses. Additional operation modes have been implemented, for example, a short-pulse operation for the investigation of the dynamics in short bunches as well as the development and tests of novel, fast diagnostic methods. The second accelerator is the linear electron accelerator FLUTE (Ferninfrarot Linac- und Test-Experiment)~\cite{nasse_flute_2013}. It is designed to provide ultra-short electron pulses with an energy of around 6 MeV after the low-energy section and with energies of up to 50 MeV and bunch lengths down to femtoseconds after the full accelerator. The electron pulses in FLUTE are generated with a femtosecond chirped laser-driven photo-injector. Of great importance for the proposed project, is the recent implementation of a spatial light-modulator which allows spatial and temporal shaping of the laser pulse and therefore control of the initial electron distribution.

Reducing side effects while maintaining or even enhancing treatment efficacy in the future will improve the quality of life of the patients. Radiotherapy uses ionizing radiation to damage the DNA within the tumor cells, which prevents the cells from reproducing and eventually leads to their death. The external beam radiotherapy (EBRT) is based on accelerator-generated high-energy beams delivering a targeted dose of ionizing radiation to the affected area. As some areas of healthy tissue are unavoidable irradiated the dose rate is carefully chosen to keep a balance between tumor control and normal tissue tolerance. The range between radiation doses that effectively destroy cancer cells while only causing minimal damage to healthy tissue and organs is called the therapeutic window \cite{vozenin_towards_2022}%[3] . A widening of this window is one of the main goals of present day radiotherapy research. -\textbf{FLASH RT} is a novel approach which focuses short pulses with very high dose rates to enhance tumor cell lethality while minimizing damage to surrounding healthy tissue.

Research results will furthermore be published in, preferably, open access journals and presented at Helmholtz meetings. % \lipsum % \lipsum \AtNextBibliography{\fontsize{8pt}{8pt}\selectfont} +\setlength\bibitemsep{1pt} \printbibliography \end{document} diff --git a/Helmholtz/full_poposal/proposal_text/proposal.toc b/Helmholtz/full_poposal/proposal_text/proposal.toc index c3a2f65..e6b271b 100644 --- a/Helmholtz/full_poposal/proposal_text/proposal.toc +++ b/Helmholtz/full_poposal/proposal_text/proposal.toc @@ -1,6 +1,6 @@ \contentsline {section}{\numberline {1}Research Goal and Expected Outcome}{2}{}% -\contentsline {section}{\numberline {2}Relation to Helmholtz Mission and Programme?}{4}{}% -\contentsline {section}{\numberline {3}Relation to Research Programme of IBPT and KIT?}{4}{}% +\contentsline {section}{\numberline {2}Relation to the Helmholtz Program}{4}{}% +\contentsline {section}{\numberline {3}The Helmholtz Investigator Group within KIT}{4}{}% \contentsline {section}{\numberline {4}Current State of Research and Preliminary Work}{5}{}% \contentsline {subsection}{\numberline {4.1}State of the art: radiotherapy}{5}{}% \contentsline {subsection}{\numberline {4.2}State of the art: accelerators and collective effects}{7}{}% @@ -13,11 +13,10 @@ \contentsline {section}{\numberline {6}Work Plan}{14}{}% \contentsline {subsection}{\numberline {6.1}Time plan}{14}{}% \contentsline {subsection}{\numberline {6.2}Group structure}{14}{}% -\contentsline {subsection}{\numberline {6.3}Existing scientific equipment and infrastructure}{16}{}% -\contentsline {subsection}{\numberline {6.4}Handling of research data/Research data plan?}{16}{}% -\contentsline {subsection}{\numberline {6.5}Financial plan}{18}{}% -\contentsline {subsubsection}{\numberline {6.5.1}Personnel costs}{18}{}% -\contentsline {subsubsection}{\numberline {6.5.2}Material costs}{19}{}% -\contentsline {subsubsection}{\numberline {6.5.3}Travel costs}{19}{}% -\contentsline {section}{\numberline {7}Cooperation and communication plan?}{20}{}% +\contentsline {subsection}{\numberline {6.3}Research data management}{16}{}% +\contentsline {subsection}{\numberline {6.4}Financial plan}{17}{}% +\contentsline {subsubsection}{\numberline {6.4.1}Personnel costs}{17}{}% +\contentsline {subsubsection}{\numberline {6.4.2}Material costs}{18}{}% +\contentsline {subsubsection}{\numberline {6.4.3}Travel costs}{18}{}% +\contentsline {section}{\numberline {7}Cooperations and Communication}{19}{}% \providecommand \tocbasic@end@toc@file {}\tocbasic@end@toc@file diff --git a/Helmholtz/full_poposal/publication_list_2024-04_helmholtz_with_awards.pdf b/Helmholtz/full_poposal/publication_list_2024-04_helmholtz_with_awards.pdf index 7e547aa..dd69b1b 100644 Binary files a/Helmholtz/full_poposal/publication_list_2024-04_helmholtz_with_awards.pdf and b/Helmholtz/full_poposal/publication_list_2024-04_helmholtz_with_awards.pdf differ
