Description

The RF Gun operating at a frequency of 178.5 MHz is used to generate an electron beam for Linac of the SKIF synchrotron. The RF Gun provides electron bunch energy up to 0.7 MeV and a charge up to 1 nK. The RF gun is a cavity at a frequency of 178.5 MHz with a built-in cathode-grid assembly that emits electrons when an unlocking pulse is applied.
The RF gun cathode-grid assembly is controlled using a set of hardware and software. Hardware includes:
• Gun Timer module for precise synchronization and triggering of the RF gun Modulator;
• Modulator that controls the cathode-grid assembly;
• controlled Power supply of the cathode-grid assembly and the Modulator;
• Phase meter with picosecond accuracy for measuring phase relationships between signals from RF gun parts.
The report describes the structure of the listed units, the features of these devices and their parameters.
Software instruments based on the TANGO platform provide setting and measurement of the cathode-grid assembly and the Modulator regimes, adjust the phase of the cathode unlocking pulses, arrange the interacting with the phase meter, and prepare data that specify the filling of the Booster separatrices. Software features listed in the report in the short form.
