Description
Technical field
The inventive method relates to a kind of ultrafast diagnostic techniques equipment, is specifically related to the assembling of streak camera core component striped image converter tube.
Background technology
Ultrafast phenomena (duration is less than 1 μ s) appears in nature or the scientific and technical research widely.For example, the photosynthesis process of plant, the ultra-large utmost point become more than duration, high light and the matter interaction physical process etc. of the ultrashort laser pulse that ultrafast photoexcited state relaxation process, the molecular dynamics process of chemical reaction, biomaterial fluorescent emission, the laser in electric pulse that circuit produces, semi-conducting material carrier lifetime, the laser material produce in psec to the femtosecond magnitude, even in Ah's second-time scope.Therefore ultrafast phenomena research is significant to the research such as natural science, the energy, material, biology, optical physics, photochemistry, laser technology, high light physics, high-energy physics and technical field.
Streak camera can provide the one-dimensional space (or spectrum), one dimension intensity and the one dimension time of ultrafast process to be total to three-dimensional ultrafast information simultaneously.Streak camera is being brought into play the effect that is difficult to substitute as the linear diagnostic tool of the ultrafast phenomena of at present unique high-spatial and temporal resolution in time-resolved ultrafast phenomena research.Streak camera mainly, image automatically controlled by fore optics system, striped image converter tube, image intensifier and coupled system, scanning is adopted the utmost point and analysis etc. and is formed.
The striped image converter tube is the core of streak camera, mainly is comprised of photocathode, accelerating system, focusing system, deflection system and detection system.Photocathode is realized the opto-electronic conversion of tested light beam; Accelerating system is axially accelerated the electronics that comprises measured target information; Focusing system realizes accelerating rear electron beam in the modulation of vertical axial direction; Deflection system is changed to spatial information by institute's making alive realization measured target temporal information; Detection system shows final result of detection, thereby has finished whole detection process.
The present invention shelves mainly for the striped image converter tube.The striped image converter tube is comprised of photocathode, grid, focusing electrode, anode, phosphor screen, its structural principle schematic diagram such as Fig. 1.Usually the striped image converter tube size of shelving after finishing can produce deviation with Theoretical Design bulk, and the reason that causes a deviation is a lot, but mainly by part's machining errors with shelve error and cause.Along with the development of process technology level, part processing can both reach theoretical permissible accuracy, therefore, shelves the main cause that error then becomes final error.At present, shelving of this type of striped pipe adopted the mandrel type molds more, utilizes electrode part inner circle location to add resistance spot welding and shelves fixing method.There is following problem in the method:
1) because electrode part thinner (0.5mm), the contact area of mandrel type mold and electrode only is the wall thickness (0.5mm) less than electrode part, and reserve mold and take out the gap of unloading, contact is almost the toroid contact, therefore can not guarantee the axiality of two electrode parts.Structural representation is seen Fig. 2, and this kind structure causes that radially to reach coaxiality deviation excessive, is difficult to guarantee.The part deviation state occurs and see Fig. 3.
2) finish and require after the assembling mold easily to take out to unload, segmentation shaft type mold quality of fit can not tension, causes axial accumulated error larger.
3) the fixing all manual operationss of assembling and spot welding are difficult to the consistency that guarantees that the striped pipe is shelved.
4) need to carry out the picture element test and appraisal by shell, often cause human and material resources to expend.As can be seen from Figure 1, striped image converter tube internal electrode is connected with shell spot welding respectively, utilizes first inner core shaft type mold to guarantee final locus as positioning datum therebetween.Must support to finish by shell when therefore, picture element is tested and assessed.
