Background technology
Ion optical lens is one of part important in all kinds mass spectroscopy device, and its function is that sample material is ionized into charged atomic ion or molecular ion.The ion beam with certain energy and geometry is drawn, is accelerated, is focused into to ion through the ion optical lens system, and then measure its mass-charge ratio value after importing the mass analyzer separation.Ion optical lens should have ionizing efficiency height, good condensing performance, ion initial energy and disperse the characteristics such as little, that efficiency of transmission is high, ion current is stable, mass discrimination is as far as possible little.The sensitivity of the quality of its performance and mass spectrometer equipment, resolution and certainty of measurement are closely related.
Because the ion optical lens system works is under vacuum environment, and the scanning voltage that will add different sizes between different pole plates distributes to form needed space electric field, therefore installation accuracy, locate mode and the rapidoprint etc. of battery lead plate in the optical lens system has all been proposed the very high requirement.At present way commonly used is to adopt ceramic gasket that each battery lead plate is separated, and re-uses steel wire and passes battery lead plate it is strained to guarantee simultaneously ion optical lens to be welded on relative position between the battery lead plate on the chamber cavity.But the design complex structure of using at present and be not easy to install, adjustment difficulty is large, just can't dismantle again installation in case assembling is finished.Thus, be necessary to provide a kind of novel packaging system.
Summary of the invention
The purpose of this utility model provides a kind of ion optical lens packaging system, and is namely a kind of complicated for mass spectroscopy device intermediate ion optical lens structure, the shortcoming of adjusting inconvenience is installed and a kind of packaging system that improves design.Device of the present utility model can effectively satisfy ion optical lens the demands such as easy to adjust, that integration good, effectiveness is good are installed, thereby lays the foundation for the commercialization of further mass spectrometer equipment unit.
Packaging system of the present utility model, include shell and can be installed in end cap on the shell by bolt, it is characterized in that, also include and be movably arranged on the end cap, be used for making three ceramics poles that are mutually hexagonal angle of battery lead plate radial location, ceramics pole can be fixed on the shell by nut.
Above-mentioned packaging system also includes the ceramic snap ring that conducting does not occur be used to the battery lead plate that makes shell and end cap and encapsulation.
Above-mentioned packaging system also includes pad and ceramic washer for the isolated electrode plate.
Be embedded with the ceramic connector for installing electrodes on the above-mentioned end cap.
The two ends of above-mentioned ceramics pole embed threaded stainless steel thread bush, are inserted with spring steel plate between ceramics pole and the stainless steel thread bush.
The designed packaged type ion optical lens device of the utility model can be encapsulated in a plurality of battery lead plates in the cavity, by ceramic connector battery lead plate is powered on.Packaging system compact conformation of the present utility model, easy installation and removal, effectiveness is good, and integration, versatility are good, have realized modularization, the integrated and miniaturization of ion optical lens design; Can extensively be suitable in the mass spectrometer equipment of various employing electronics bombardment excited ions.

Fig. 1: the general structure schematic diagram of packaging system of the present utility model (top is end cap);
Fig. 2: the decomposition texture schematic diagram of packaging system of the present utility model;
Fig. 3: the structural representation of ceramics pole of the present utility model;
Wherein: 1, shell 2, outlet seam 3, intensifying ring 4, focusing electrode 5, extraction pole 6, end cap 7, ceramics pole 8., ceramic snap ring 9, pad 10, ceramic washer 11, nut 12, ceramic connector 13, electrode 14, bolt 15, stainless steel thread bush 16, spring steel plate.
Embodiment
Such as Fig. 1, ion optical lens packaging system of the present utility model will place cylinder blanket 1 interior encapsulation for four battery lead plates (outlet seam 2, intensifying ring 3, focusing electrode 4, extraction pole 5) of electron focusing and acceleration.Use ceramic snap ring 8 to separate to guarantee not conducting between its middle outlet seam 2 and the shell 1, shell 1 inner surface has groove can make ceramic snap ring 8 locate fully.Use ceramic washer 10 that it is kept apart mutually between intensifying ring 3 and outlet seam 2 and the focusing electrode 4; For guarantee ceramic washer 10 can with battery lead plate on through hole coaxial, it is used for location ceramic washer 10 with pad 9 welding to adopt spot welding method at the battery lead plate of intensifying ring 3.In like manner, at the through hole both sides point welding pad 9 of focusing electrode 4 and outlet seam battery lead plate 2, be used for location ceramic washer 10 respectively.Between extraction pole 5 and end cap 6, also separate to guarantee not conducting with ceramic snap ring 8.Because therefore the radially not constraint of battery lead plate is so that the battery lead plate centre bore can be coaxial, has used three long ceramics poles 7 to be mutually hexagonal angle and passed 3 through holes that are mutually hexagonal angle on the battery lead plate.Because three through holes crossing on range request ceramics pole 7 and the battery lead plate in processing manufacture, thereby can guarantee good quality of fit, can guarantee that namely four plate electrode plates are coaxial.
Embed threaded stainless steel sleeve 15 at the two ends of ceramics pole 7, be that spring steel plate 16 by four cydariforms guarantees to clamp between ceramics pole 7 and the stainless steel sleeve 15, and the spring steel plate 16 of cydariform adopt the mode of means of spot welds to be welded on the inwall of stainless steel sleeve 15 (Fig. 3).Like this, ceramics pole 7 just can be fixed on shell 1 and the end cap 6 by nut 11.
In the process that this device is installed, at first then ceramic gasket 9 and battery lead plate vertical arrangement should be inserted ceramics pole 7 from three through holes successively, finish the radial location of battery lead plate.The battery lead plate power supply being drawn ceramic connector 12 top electrodes 13 is brazed together with each battery lead plate again; To be inserted in the multistage earthenware on the power line to prevent each power line contact short circuit in cavity.At last it is put into shell 1 in the lump, buckle into the ceramic snap ring 8 of end cap 6 compressions and reach requirement to guarantee four plate electrode plate axial distances.End cap 6 is fixed on the shell 1 by bolt 14, screws in the nut 11 that can cooperate with it at the ceramics pole 7 that stretches out, and assurance ceramics pole 7 can not deviate from easily, has so just finished the installation of whole ion optical lens.Whether the use universal instrument detected between each battery lead plate and isolates fully after assembling was finished.
The utility model of constructing thus is rational in infrastructure, and reliability is high, is one of various critical components that need electronics bombardment excitated type ionization massspectrum instrument, also can be widely used in the various electron gun equipment.
