Solid target system for radionuclide preparation

A solid target system for radionuclide preparation, comprising:

• a first cassette in which a solid target component is provided;
• an ejection sub-system;
• a laser radar positioning sub-system;
• a control cabinet;
• a cooling sub-system;
• a fixing base;
• a workbench;
• and
• a flange;
• wherein the first cassette is arranged at a center of the solid target system;
• a back of the first cassette is provided with an upper water supply pipe, a drainage pipe and a lower water supply pipe in sequence from top to bottom;
• the upper water supply pipe and the lower water supply pipe are connected to a water supply end of the cooling sub-system;
• and the drainage pipe is connected to a drainage end of the cooling sub-system;
• the ejection sub-system is arranged directly behind the first cassette;
• and the ejection sub-system is configured to eject the first cassette to fall into a recovery hole after the solid target component is bombarded;
• the laser radar positioning sub-system is configured to transmit position information of the ejection sub-system to the control cabinet in real time;
• the control cabinet is electrically connected to the laser radar positioning sub-system, and is configured to control an operating state of the ejection sub-system, so as to eject the first cassette to the recovery hole after the solid target component is bombarded;
• the cooling sub-system is configured to cool down the solid target component with a cooling water;
• and the cooling water is configured to flow from the water supply end of the cooling sub-system to the solid target component to cool the solid target component, and flow back to the cooling sub-system through the drainage end of the cooling sub-system;
• the fixing base is connected to the workbench through a first guide rail, such that the workbench is slidable forward and backward on the fixing base;
• and the first cassette, the ejection sub-system, the laser radar positioning sub-system, the cooling sub-system and the control cabinet are mounted on the workbench;
• and
• the flange is fixed on an accelerator, and is configured to guide a beam of the accelerator to the first cassette.
