Problems solved by technology

[0003] The current open ion source technology mainly has the following deficiencies: the ion source heat transfer heating technology can quickly realize the heating of the equal-diameter space, and due to the use of hollow air and external sealing, the heat loss is large and the utilization rate is not high. , when rapid cooling is required, the cooling time is too long, which makes the waiting time of the experiment too long; the ion source fan cooling technology, due to the discharge characteristics of the ion source, placing a fan outside the good heat preservation device is effective for high temperature in a short time, but in the medium The effect of the temperature section is not obvious, and the cooling time is slow, which makes it impossible to meet the technical requirements for rapid heating and cooling

Description

technical field [0001] The invention relates to an ion source, in particular to an ion source with a temperature control function and a working method thereof. Background technique [0002] During the working process of the open ion source, when the high-temperature sample is ionized, the temperature of the discharge gas should be raised in a sealed environment without electronic interference to increase the ion velocity intensity and ion beam energy of the gas, which is conducive to the ionization of the sample. . When analyzing samples with a lower ionization temperature, the ion source needs to be cooled rapidly in a sealed environment to reach the expected temperature range. Therefore, the rapid realization of the temperature control of the ion source is conducive to the orderly and rational conduct of the experiment. [0003] The current open ion source technology mainly has the following deficiencies: the ion source heat transfer heating technology can quickly realiz...
