Problems solved by technology
The shortcoming of existing " look-up table method " is: the number of superconducting cavities in the ADS accelerator is numerous, the situation is complicated, the amount of data of the parameter table is extremely huge, and the time of table look-up is also long; Superconducting through emulation software (such as TRACEWIN) The calculation of cavity failure compensation takes a long time and the workload is heavy
In addition, if there is a change in the accelerator structure (lattice) in the later stage, a lot of work needs to be done again, and it is very difficult to maintain and update the parameter table

The invention discloses a super-conducting cavity failure compensation method, apparatus, equipment and a storage medium. The compensation method comprises the steps of collecting an electric signal of each super-conducting cavity, determining a control signal of an accelerator element which participates in compensation according to the electric signal, and taking the control signal of each accelerator element as multidimensional input variables to establish a linear regression model; solving the linear regression model through a genetic algorithm to obtain an updated value of the control signal of each accelerator element; and setting the configuration of each accelerator element according to the updated value of the control signal of each accelerator element to enable a beam current to satisfy preset requirement. According to the technical scheme provided by the embodiment, by establishing the linear regression model with the multidimensional input variables, the problems of calculation time consumption and difficulty in maintenance caused by the existing look-up table method can be solved.
Description
technical field [0001] The present disclosure generally relates to the field of accelerator control, and in particular to a superconducting cavity failure compensation method, device, equipment and storage medium. Background technique [0002] Radio-frequency superconducting technology has become the mainstream technology and development direction of large-scale accelerators, and is widely used. However, due to the complex technology, in superconducting accelerators, the failure of radio frequency superconducting cavity is the most important and common type of failure, and it is also a key factor affecting the reliability of the accelerator. Compared with other accelerators, the high-current proton superconducting accelerator of the Accelerator Driven Sub-critical Nuclear Energy System (ADS: Accelerator Driven Sub-critical System) has a special application-sudden beam interruption will cause ADS to shut down for a long time, It even causes severe temperature and stress chan...
