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 scientific and technical research widely.Such as, the duration, strong light-matter interaction physical process etc. of the ultrashort laser pulse that the electric pulse that the photosynthesis of plant, ultra-large pole become circuit to produce, semi-conducting material carrier lifetime, the ultrafast photoexcited state relaxation process in laser material, the molecular dynamics process of chemical reaction, biomaterial fluorescent emission, laser produce many in psec to femtosecond magnitude, even within the scope of Ah's second-time.Therefore ultrafast phenomena research to the researchs such as natural science, the energy, material, biology, optical physics, photochemistry, laser technology, high light physics, high-energy physics and technical field significant.
Streak camera can provide the one-dimensional space of ultrafast process (or spectrum), one dimension intensity and one dimension time three-dimensional ultrafast information altogether simultaneously.Streak camera, as the linear diagnostic tool of ultrafast phenomena of high-spatial and temporal resolution unique at present, to play the effect being difficult to substitute in time-resolved ultrafast phenomena research.Streak camera is automatically controlled primarily of fore optics system, striped image converter tube, image intensifier and coupled system, scanning, the composition such as IMAQ and analysis.
Striped image converter tube is the core of streak camera, forms primarily of photocathode, accelerating system, focusing system, deflection system and detection system.Photocathode realizes the opto-electronic conversion of tested light beam; Accelerating system carries out axial acceleration to the electronics comprising measured target information; Focusing system realizes the modulation of electron beam in vertical axial direction after acceleration; Deflection system realizes measured target temporal information by institute's making alive and changes to spatial information; Detection system shows final result of detection, thus completes whole detection process.
The present invention shelves mainly for striped image converter tube.Striped image converter tube is made up of photocathode, grid, focusing electrode, anode, phosphor screen, and its structural principle schematic diagram is as Fig. 1.Usual striped image converter tube shelved after size can produce deviation with Theoretical Design bulk, the reason caused a deviation is a lot, but primarily of part's machining errors with shelve error and cause.Along with the development of process technology level, part processing can reach the precision of theory calls, therefore, shelves the main cause that error then becomes final error.At present, shelving of this type of streak tube adopts mandrel type mold more, utilizes electrode part inner circle location to add resistance spot welding and shelves fixing method.There is following problem in the method:
1) due to electrode part thinner (0.5mm), the contact area of mandrel type mold and electrode is only the wall thickness (0.5mm) being less than electrode part, and reserve mold and take out the gap unloaded, contact is almost annular line contact, therefore can not ensure the axiality of two electrode parts.Structural representation is shown in Fig. 2, this kind of structure radially and coaxiality deviation excessive, be difficult to ensure.Occur that part deviation state is shown in Fig. 3.
2) require after completing assembling that mold easily takes out to unload, segmentation shaft type mold quality of fit can not tension, causes axial accumulated error larger.
3) assembling and the fixing all manual operationss of spot welding, be difficult to the consistency ensureing that streak tube is shelved.
4) need can carry out 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, first utilizes inner core shaft type mold therebetween as positioning datum to ensure final locus.Therefore, must support by shell during picture element test and appraisal.
