Research On Data Acquisition And Processing Of Field Mapping System For Cyclotron Magnet

Compact Cyclotrons are wildly used in the fields of nuclear medicine and nuclear physics and others, especially in radioisotope production. But there are large gaps in cyclotron design and manufacture level between Chinese and advanced international, the lack of the cyclotron with independent intellectual property rights, therefore, to strengthen the development of high-performance work cyclotron is imperative.In order to meet the conditions of cyclotron operation and to improve the performance of the accelerator, the accelerator's main magnetic field need to strictly appease the design requirements, it is essential measure the main magnetic field of cyclotron in high-precision and high-density, which provide the measured data for the particle dynamics calculated. In brief, the magnetic result of the magnetic field measurement system is important for the successful build of cyclotron.First, this article described the technical requirements, design ideas and program design of the magnetic field measurement system of CYCHU-10, program design which is divided into the mechanical system design and measurement system designed to introduce. Secondly, introduce the using of the measurement system in detail, including the Tesla and the Hall probe, the servo motor drives, the servo motor motion control card, straight-line grating ruler, and explain the reasons for the selection of details and components of the parameters.Finally, when finish the data-acquisition system and data-processing system which are based on the LabVIEW 8.6, take the relevant verification experiment according to the results of measuring system design requirements, and lists the relevant experimental results and analysis.
