Description
Computer technologies are widely used to monitor the beam dynamics in synchrotrons. These charged particle accelerators are advanced equipment used for studying the structure of matter in particle and nuclear physics. Nuclotron-based Ion Collider fAcility (NICA accelerator complex) is a new basic facility of the Joint Institute for Nuclear Research in Dubna. The complex aimed for acceleration of heavy ions includes linear accelerator and 3 synchrotrons: Booster, Nuclotron, Collider. The NICA Collider must ensure collisions of beams of heavy-element nuclei such as 197Au79+ with a center-of-mass energy of 4-11 GeV/n.
The Booster, a new superconducting synchrotron that was launched in December 2020, and the Nuclotron, a superconducting synchrotron that was commissioned in 1993 and upgraded between 2024 and 2025, are currently undergoing joint tuning for the acceleration of Xenon ions. During the acceleration cycle in Booster and Nuclotron accelerated particles make hundreds of thousands of revolutions. The stability of the beam is greatly enhanced by computer technologies. As a result, controlling the parameters of bunches is an essential procedure.
Some examples are presented in the report:
- control of synchrotron oscillations of a bunch injected into the Booster or the Nuclotron,
- estimation of longitudinal momentum spread of ions in the bunch,
- tomographic reconstruction of the longitudinal phase space distribution of ions in the bunch.
