Beam Dynamics, Cooling Methods and New Methods of Particle Acceleration


One of the processes leading to the vacuum conditions degradation when working with a gold bare nuclei beam in the NICA Collider can be the electron clouds effect. Influence of electron cloud densities on the coherent tune shift of ion betatron oscillation in the Collider ring was investigated for different bare gold nuclei beam intensity, its energies and electron secondary emission yields from the Collider vacuum chamber. The pressure rise due to additional gas load and heat load caused by electron clouds are estimated.
