The beam dynamic characteristic in the cooling storage ring is measured with the schottky probes. The relative momentum spreadΔp/p of the beam, the value of the tune Q, the revolution frequency of particles along the ring circumference and particle number can be acquired by the Schottky signal.

All of the beam diagnostic probes have been redesigned and changed along the beam transport line from ECRS to CSRm. The typical probes used in HIRFL are FC(Faraday cup),VS(viewing screen) and Slit.

The slits are important for the beam tuning and physics experiments which are used to limit the beam. More than ten sets of slits are installed along the ECRS to CSRm beam transport line. The stepping motor controller for slits and other beam diagnostic probes is developed based on the microprocessor AT89C51. Fig. 1 shows the structure of stepping motor for the beam diagnostic system.展开更多

The system consists of the data acquisition, data analysis, and data display. The low beam current from FC is measured automatically by the system through signal acquisition, signal transformation, signal amplification, pulse signal shape rectification, A/D conversion, data treatment and result display. The structure diagram of the low beam current measurement system is shown in Fig. 1.展开更多
