  NICA (Nuclotron based Ion Collider fAcility) is an accelerator complex, which is being built in JINR (Dubna, Russia). The system described in this paper is controlling the RF stations of booster, the first element of the NICA complex. The two devices are parts of the Control System: Intellectual Controller and Tester module. The first one is designed for precise measurement of magnetic field, generation of the acceleration frequency in accordance with measured field and control RF power and pre-amplifiers. Intellectual Controller is a real-time feed-forward system with 20 ums loop time. It is based on ARM microcontroller and bare-metal control programs are used to reach maximum performance. Approaches that were used to achieve maximum performance are elaborated and presented in this paper. The second part of system - Tester is a simulator for tuning and checking the RF stations before start of operations or in absence of real accelerator. The achieved accuracy in chain 'magnetic field' - 'acceleration frequency' is better than 5*10-5. Plans on feedback incorporation to stabilize ion beam behavior via frequency and phase tuning are discussed.

  The TPS is a state-of-the-art synchrotron radiation facility featuring ultra-high photon brightness with extremely low emittance. Its Booster has 6 FODO cells which include 7 BD dipoles with 1.6 m long and 2 BH dipoles with 0.8 m long in each cell. After magnetization of stainless steel vacuum chamber of the booster were identified and then dismantled, annealed, and re-installed, the electron beam energy of the Taiwan Photon Source (TPS) in the booster ring has ramped to 3 GeV in a week. The booster tune correction during ramping is one of the main reasons why the booster commissioning progress is so fast. In this paper the summarized the booster tune monitor system will be summarised

  This paper presents a system for acquiring and sorting data from select devices depending on the destination of each particular beam pulse in the Fermilab accelerator chain. The 15 Hz beam that begins in the Fermilab Linac can be directed to a variety of additional accelerators, beam lines, beam dumps, and experiments. We have implemented a data acquisition system that senses the destination of each pulse and reads the appropriate beam intensity devices so that profiles of the beam can be stored and analyzed for each type of beam trail. It is envisioned that this data will be utilized long term to identify trends in the performance of the accelerators.
