C:/users/lenovo/desktop/1. Gif is a type of electron accelerator which is an accelerator with electric particles transmitted along a straight orbit at a high-frequency field acceleration. The electron straight-line accelerator is a microwave accelerator, which is generally high (>5mev) with output power ranging from thousands to dozens of kilowatts. The maximum energy of industrial irradiated electro-line accelerators is generally set at 10 mevs due to safety restrictions on radiation exposure. The use of electro-linear accelerators is wide-ranging and at present, mainly for medical devices and hygiene, irradiation, food irradiation protection, food infestation, export and import food testing and quarantine, antibiotic degradation, environmental protection, semiconductor modifications, development of new chemical products, etc. I.

The electronic straight-line accelerator system electronic guns are the electronic source of accelerator, which produces a certain energy, flow and shape-required electronic beam and enters the accelerator tube for acceleration. The electronic gun is a bipolar pearce electronic gun and consists of cathodes (cathode thermal components), focus poles and anodes. The electrons launched by the cathode, with a focused focus, enter the accelerator via the anode hole and have a flow factor of 0. 068. According to the design requirements of the accelerator, the working voltage of the electronic gun is 55-65 kv, and the launch beam is continuously modifiable with a maximum beam of 1a. Note:
1) the cathode does not allow long-term exposure to the atmosphere
2) e-guns work in temperature limits

A) the tubes may not contain very negative gases such as fluorine (f2), chlorine (cl2), oxygen (o2), carbon monoxide (co), sulphur dioxide (so2) and water vapour (h2o), even if low pressure can cause cathode poisoning and minor poisoning can cause instability of the cavity。

Ii. Accelerator tubes are currently 10 pages, totalling 21 pages. The electronic straight-line accelerator system beam transmission system consists of two components: a focal circle and a beam output system. Focused wires are used to overcome the dispersion of the accelerator mid-wire charge to the electric field and space charge to obtain good beam properties. The output system consists of an output orientation, a beam of influenza response loops and a drift tube, an output orientation to guide the electronic accurate entry of the accelerator into the beam flow measurement sensor and scanning system, and a beam of influenza to detect the output pulse flow of the accelerator. The structure of the accelerator beam transfer system is as follows: iii, the current 11-page beam transmission system, with a total of 21 pages. The microwave power source of the electronic straight accelerator system consists of solid-state sources, fast-temperators and modems. Solid-state sources are available for fast-tip microwave signals. The modem provides the wiring currents and high pressure pulses for the speed tube, while providing -60kv pulses for the electronic gun. The accelerator is a cyclical modulated electronic accelerator that achieves oscillation or amplification by magnifying microwave signals from solid sources (pulse power greater than 100 w) to pulse power greater than 3. 5 mw. The structural relationship between the three is shown in the figure below: iv. Microwave power sources are currently 12 pages and total 21 pages.

The electronic straight-line accelerator system vacuum system consists of electronic guns, accelerator tubes (including input, output couplings), a beam-out-out system (including output x, y-direction, influencing, drift tubes), scanned windows, ion pumps and flexible wave conductors, empty pipes and ultra-high vacuum valves. A vacuum system can guarantee the normal launch of accelerator electrons, the normal transmission of accelerator beams, and ensure that accelerators and microwave components are not punctured by high-power microwave signals. The accelerator vacuum system requires an ion pump to work 24 hours a day without interruption, even if the accelerator is not properly beamed. This must be taken into account when supplying electricity. The working vacuum shall be greater than 5 x 10-6 pa. Vi. The vacuum system is currently 14 pages in total of 21 pages. The electron straight-line accelerator system's thermostat system consists of a heating and water cooling system. The working temperature of the constant water requires 38 °c ± 0. 5 °c and a total flow of 5. 5 t/h. The water cooling system uses circular distillation water for cooling. The thermostat system provides a quantitative, constant-temperature cycle distillation water to keep the accelerator at constant temperature and cools the main heating components of the accelerator to ensure that the accelerator meets the rated technical targets to enable it to work safely and securely over the long term. Vii. The thermostat system currently stands at 15 pages, with a total of 21 pages. The electron straight-line accelerator system inflates with sulphur hexafluoride gas, which acts: 1) to increase microwave insulation to prevent fire; 2) to produce ceramic window dissipation from fast-paced tubes. The structure of the inflatable operating system is as follows:
1 - cylinder 2 - pressure-relief valve 3 - filter dryer 4 - inflatable valve 5 - discharge valve 6 - gas dispenser (five)
7-atmosphere pressure table 8-isolation valve 9-small pressure gauge (all upper and lower-protected contact signal output). The electrical control system of the electronic straight-line accelerator system consists of plc and aic. The accelerator program control is the organic linking of the subsystems of the accelerator (e. G., focus power, electronic guns, accelerators, transceivers, transceivers, microwave systems, inflating systems, heating systems, vacuum systems, and beamed scanners) to provide power and control signals according to certain procedures that enable the accelerator to automatically generate accelerator energy, beam flow, scanning width and automatic opening, and to turn off high pressure by operation keys in accordance with preset processes. Electrical control systems are modular, logical, reliable and easily maintained. Ix. The electrical control system is currently 17 pages in total of 21. The electronic straight-line accelerator system beam-scan system is a transversal magnetic field that allows the electronic beams from which the accelerator is exported, which is subject to the force of lorentz, scans back and forth in the direction of the beam flow and magnetic field vertically, while the irradiated objects are placed on the delivery line and move forward vertically in the scanning direction, thus guaranteeing the basic requirements for radiation exposure. It is structured as follows: x. The beam-stream scanning system is currently 18 pages, with a total of 21 pages. The electron straight-line accelerator system consists of 5-8 groups of steady current power, output x, y-directed power and scanning power, all of which are controlled and controlled in two modes: at the time of this control, the currents of each power source can be regulated by panels; at the time of remote control, they are controlled by built-in control circuit boards。

The main structure of the electronic straight-line accelerator system for the seaway electro-line accelerator is a stand-alone structure, characterized by: (1) the weight of the accelerator tube, cooling water kit, and the concentration ring is carried over the base bearing plate, and the tolerance of the accelerator and cooling water kit can be adjusted by the flexible support unit, which has been reconciled at the time of installation and must not be adjusted on its own. (2) platforms, cabinets and main structures are not linked to prevent vibration from passing to the main structure. N. B. The main body is not allowed to have a shock effect because of its high vertical focus. When flexible supports are installed, they are not normally allowed to adjust themselves. Xii. The mechanical main support system is currently 20 pages, for a total of 21 pages. The electronic straight-line accelerator system, the wind cooling system, provides wind cooling for wave conductors, titanium windows and beam transmission units, and cooling for wave conductors, titanium membranes and beam transmission units. Once the wind is cold or work is stopped, the system will alert to malfunctions and ensure that wave conductors, titanium membranes and sub-beam transmission units are not damaged by excessive temperatures.
