2. Crystal channeling for the beam loss mitigation in slow extraction at 8GeV

Vladimir Nagaslaev (Fermilab)

Mitigating beam losses is the central challenge in slow extraction, and it is becoming increasingly critical as beam power continues to rise. A highly promising mitigation technique—proton beam channeling in a crystal—has been successfully demonstrated at the CERN SPS using 400 GeV beams, effectively steering the beam away from the extraction septa. There is strong interest in evaluating the...

3. Quantum tunneling and above-barrier reflection of high-energy positively charged particles in oriented crystals

Dr Miccola Bondarenco (NSC Kharkov Institute of Physics and Technology, Ukraine)

Channeling of fast charged particles in oriented crystals is usually amenable to classical treatment. Quantum effects, though, are known to exist for electrons with energies up to 100 MeV, manifesting themselves as a zone structure in the transverse energy spectrum. For positrons, the top of the potential barrier is narrower, so tunneling and above-barrier reflection is expected to occur at...

1. Transportation of Ramped Bunch Train in a Layered Plasma Wakefield Accelerator

Prof. Gennadiy Sotnikov (National Science Centre Kharkov Institute of Physics and Technology)

Electron beam-driven plasma wakefield accelerators (PWFAs) are currently being intensively developed for future applications in high-energy physics and industry due to their ability to provide a high acceleration gradient. Among the key unresolved challenges of PWFAs is maintaining high quality of accelerated (witness) and drive bunches (emittance, energy spread, efficiency) during their...
