Main Goals
The WP2 aims to design, develop and test new approaches for the generation of charged particle or high energies photon beams with FLASH characteristics. WP2 will be organised in 5 Tasks covering the most novel worldwide accelerator R&D to allow reliable flash beams. WP2 explores conventional approaches for high gradient and high charge acceleration as well as plasma based compact sources for protons and electrons.
Task 1 - Compact accelerating structure for C-band VHEE LINAC
6GHz accelerating structures may provide 100 MeV electron beams in a few meters. Beam dynamics simulation and RF design of the main LINAC will be pursued. A full-scale prototype will be realized and bench tested.
Task 2 - RF Pulse compressor SLED for C-band VHEE LINAC
Task 2 focuses on the design of a klystron pulse compressor for a high-field and compact LINAC. A full scale prototype will be realised and bench tested.
Task 3 - Proton beams from laser-plasma interactions
New and specifically designed coil-shaped targets coupled with permanent magnetic quadrupoles will be used to improve the emittance and the energy of the laser-accelerated proton beams. This scheme will be studied and optimised to obtain a never reached regime of tens of Gy in tens of nanoseconds over a 1 cm in diameter homogeneous beam spot size.
Task 4 - Electron beams from laser-plasma interactions
The VHEE electron beam already available at the CNR-INO ILIL laboratory will be optimised to:
i) further increase the dose/dose-rate, also using a dedicated transport beamline (CNR in-kind contribution to the project);
ii) enhance the control on the energy spectrum.
The experimental set up will enable in depth dosimetry of a VHEE pencil-beam configuration with high dose rate.
Task 5 - High current medium energy electron beams for medical applications
Feasibility studies will be performed for the generation of up to 10 MeV photon beams and impressive flux of 1016 photons/s. This will be possible thanks to the activities related to the future BriXsino accelerator (MI) that will be able to produce electron bunches with a charge up to 50 pC at a repetition rate up to 100 MHz.
