[0003] Electron cyclotron resonance ion source (ECR ion source) is a kind of equipment capable of generating high-charge state ion beam, is a kind of magnetic confinement plasma device based on magnetic field electron cyclotron resonance, microwave heating ionization, ion source provides the proton beam flow required by BNCT accelerator, proton beam flow is accelerated by RFQ accelerator, and Li target is produced Neutron, neutron is screened and integrated after slowing down and shaping and used to treat cancer. The working principle of ECR ion source is to excite gas molecules in a specific magnetic field using microwave energy, generate plasma, and then generate the required ion beam. When microwave energy enters the discharge chamber through the microwave input window, under the action of the high-strength magnetic field generated by the permanent magnet system, the outer electrons of the gas molecules will do cyclotron motion. When the cyclotron frequency is equal to the applied microwave frequency, resonance state is reached, and electrons can accept energy from microwaves, increase electron temperature, and ionize gas.

[0004] ECR ion source equipment is precisely connected with low-energy beam section (LEBT), RFQ accelerator section and high-energy beam section (HEBT section) through vacuum pipeline, and high concentricity is required for the pipeline, so the ECR ion source equipment needs to be connected with LEBT section multiple times during installation and assembly of the equipment, because RFQ accelerator section is installed at the time of installation, and RFQ accelerator section is the core of the entire accelerator, and is the main acceleration equipment section for particle energy to reach the theoretical value, and the length of the section is relatively long, so other accelerators need to be matched with it, and after LEBT section is connected, ECR ion source section needs to be connected with LEBT section. When ECR ion source and LEBT are connected by pipeline, assembly requirements are required for concentricity, however, most of the wheels for equipment installation are foma wheels, the wheel diameter of foma wheel is too small, the ground is complex during on-site installation, and large depressions cannot be passed, although foma wheel has certain lifting function, but the lifting space is limited, and once raised, the fixing device contacts the ground, and the wheel cannot move forward.
