Description

Technical field: [0001] The invention relates to the technical field of a construction method of a multipurpose proton-heavy ion research device, in particular to a cascaded cyclotron and double cooling storage ring system. Background technique: [0002] As a well-known proton-heavy ion accelerator, the cooling storage ring uses a magnetic field (to change the direction of movement of ions) and an electric field (to accelerate or decelerate ions) to synchronize the operation with the ions moving in the storage ring, so that the ions in the cooling storage ring energy change and storage. Cooled storage rings, as a kind of infrastructure for proton-heavy ion physics research, have been described in the prior art. [0003] The disadvantage of the proton-heavy ion cooling storage ring disclosed in the prior art is that in the devices that use a cyclotron as the cooling storage ring injector, one cyclotron is used. Since the energy range to which the cyclotron can be accelerate...

[0003] The disadvantage of the proton-heavy ion cooling storage ring disclosed in the prior art is that in the devices that use a cyclotron as the cooling storage ring injector, a cyclotron

Since the energy range to which the cyclotron can be accelerated is limited by magnets and high-frequency equipment, if there is a large difference between the ion energy provided by the ion source and the lowest ion energy that the cooling storage ring can accept, the cyclotron as an injector is required There is a wide energy range, which means that the process complexity and cost increase

However, in the device that uses a linear accelerator as a cooling storage ring injector, the linear accelerator can only provide pulsed proton-ion beams, and the cost is relatively high and the area occupied is relatively large.

At the same time, these accelerator devices all have a common defect. The cooling storage ring only adopts a single-ring structure, and the experimental platform cannot be set up separately, which makes the experiment interfered and restricted by the process of improving the beam quality.
