Dr. Atoosa Meseck
The member of BESSY staff works on accelerator physics
Atoosa Meseck, born in Teheran (Iran), studied Physics at Hamburg University. She completed her PhD thesis (Dr. rer. nat) at “Deutsches Elektronen Synchrotron” (DESY) in the year 2000 in the area of accelerator physics. The subject of her work was of great importance for the experiments at the electron ring of HERA: „The Electron Distribution in HERA and the Consequences for the H1 Detector after the Luminosity Upgrade“.
Following her PhD she started work as postdoc at the former Hahn-Meitner-Institut Berlin, where she engaged in designs for production and acceleration of Heavy Ions at the ISL cyclotron facility. Getting interested in modern electron-based light sources, as free electron lasers (FELs), she came to BESSY in 2003. There she worked initially “in the front line“ for the technical design of the BESSY Soft X-ray FEL.
Her responsibility was not only the conceptual design of the FEL but also to direct her students in the development of numerical codes for the calculation of various interactions of charged particles with electromagnetic waves. The codes - new and improved ones -, are now available as open-source codes for colleagues all over the world and are used as essential tools for the development of modern light sources e.g. FELs.
Besides the development of new methods in accelerator physics the theoretical and experimental monitoring and backing of the implementation of these methods is focus of Dr. Mesecks work. She is engaged in the Optical Replica Synthizer (ORS) experiment at FLASH in Hamburg. ORS is a clever way of diagnosing all the properties of electron beams essential for the FEL process.
The simulation codes developed by her group are employed in designing crucial experiments at modern FELs, e.g the “sFLASH”- experiment at DESY. At sFLASH seeding of an FEL with short wavelength radiation from an HHG-laser source will be investigated (upper part of the figure). Atoosa Meseck is very engaged in design and realization of this experiment.
At FLASH II, a further development of the existing FEL-facility at Hamburg, the cascaded HGHG concept developed by Dr. Meseck for the BESSY-FEL will be realized. The lower part of the figure shows the expected essential improvements a cascaded HGHG FEL can provide. Dr. Meseck will be responsibly coordinating the implementation of the HGHG-FELs at FLASH II for Helmholtz-Zentrum-Berlin.
