Description
Although the cyclotron accelerators at HIRFL, namely the Sector-Focused Cyclotron (SFC) and the Separated Sector Cyclotron (SSC), are over sixty years old, beam commissioning continues to run successfully. The SFC, installed in 1962, can accelerate heavy ions to 17 MeV per nucleon or protons to 37 MeV, with an average current of 10 µA. The SSC (Sector-Separated Cyclotron), commissioned in 1975, serves as our primary accelerator. It is capable of accelerating ions to energies of up to 100 MeV per nucleon or protons to 110 MeV.We will present advancements in beam diagnostics designed to enhance machine operation efficiency and convenience, as well as to enable more precise and comprehensive measurements of beam parameters. The primary focus includes the development of key sensors and electronics tailored to meet the requirements for low-intensity current and transverse emittance measurements. Additionally, it presents the design and implementation of a beam diagnostics control system based on a cloud architecture, operating on a highly reliable server cluster. Native device control and data processing software run within virtual computers on the cloud platform, enabling comprehensive beam measurements including beam current, position, transverse profile, emittance, energy, and longitudinal bunch length. The system apples the EPICS communication protocol and features an integrated user control interface.
