Thus, under normal conditions, the gas in the tube does not discharge; when high-speed particles are injected into the tube, the energy of the particles ionizes and conducts the gas in the tube, and a rapid gas discharge phenomenon is generated between the filament and the tube wall, so that a pulse current signal is output. By appropriate selection of the voltage applied between the filament and the wall of the tube, the lowest energy of the detected particle and thus its species can be selected.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The following terms are used herein.
A pressure reducing valve: the valve is a valve which reduces the inlet pressure to a certain required outlet pressure by regulation and automatically keeps the outlet pressure stable by means of the energy of a medium. From the viewpoint of hydrodynamics, the pressure reducing valve is a throttling element with variable local resistance, namely, the flow speed and the kinetic energy of fluid are changed by changing the throttling area to cause different pressure losses, thereby achieving the purpose of pressure reduction. Then, the fluctuation of the pressure behind the valve is balanced with the spring force by means of the regulation of the control and regulation system, so that the pressure behind the valve is kept constant within a certain error range.
Two-position two-way electromagnetic valve, a mechanical principle combining direct action and pilot type. Electromagnetic valves are divided into two main categories in principle: 1) Direct-acting solenoid valve: the principle is as follows: when the valve is electrified, the electromagnetic coil generates electromagnetic force to lift the closing piece from the valve seat, and the valve is opened; when the power is cut off, the electromagnetic force disappears, the spring presses the closing part on the valve seat, and the valve is closed. The method is characterized in that: can normally work under vacuum, negative pressure and zero pressure, but the drift diameter is not more than 25mm generally. 2) Step-by-step direct-acting electromagnetic valve: the principle is as follows: when there is no pressure difference between inlet and outlet, after power is on, the electromagnetic force directly lifts the small pilot valve and the main valve closing part upwards to open the valve. When the inlet and the outlet reach starting pressure difference, after the power is switched on, the electromagnetic force leads the small valve, the pressure of the lower cavity of the main valve rises, the pressure of the upper cavity falls, and therefore the main valve is pushed upwards by utilizing the pressure difference; when the power is cut off, the closing member is pushed by the pilot valve by spring force or medium pressure to move downwards, so that the valve is closed. Wherein, above-mentioned two types of two-position two-way solenoid valve all is applicable to this application embodiment.
Mass flow controller, english full name: mass Flow Controller, abbreviated as MFC, is an instrument used for precisely measuring and controlling the Mass Flow of gas or liquid. The flow rate display device is generally composed of components such as a flow rate sensor, a flow rate regulating valve, an amplification control circuit, a shunt control channel and the like, and the working power supply, the flow rate display, the setting and other operations of the flow rate display device are provided by a flow rate display power supply matched with the working power supply.
Check valves, also known as check valves or back-flow valves, are devices in which gas can only flow in one direction, but cannot flow back.
A rotor flowmeter, also called a variable flow area constant differential pressure flowmeter or a float flowmeter, measures fluid flow according to the throttling principle, but changes the flow area of the fluid to keep the differential pressure above and below a rotor constant.
In the related art, the inventor does not find a protection system for a detector, and in order to overcome the defects in the prior art, the protection system for the detector is provided to solve the technical problems that the gas cannot be found in time when the gas is abnormal and the device is not high in stability due to the fact that the gas easily penetrates through the detector in the past and the detector is damaged.

the gas one-way control module 16 is used for controlling the gas of the corresponding gas branch to carry out one-way output;
when the system detects that the gas flow is abnormal, the system controls the quality control module to adjust the preset flow and controls the switch control module 13 of the gas branch corresponding to the abnormal gas flow so as to disconnect the corresponding gas branch.
It should be noted that, if the number of the detectors is increased, the system controls the quality control module to increase the preset flow rate; if the number of detectors is reduced (e.g., damage occurs), the system controls the quality control module to reduce the preset flow rate.

Meanwhile, the system correspondingly closes the switch control module A, so that an abnormal gas branch can be cut off, and the waste of gas used in the system work can be avoided. So far, when one or some gas branches in the system have abnormality, the detectors 14 of other gas branches can be protected, so that other gas branches can work normally, and the use of users is not influenced.
