Description
Technical Field
The invention relates to the technical field of microchannel plates, in particular to edge-coated glass, a preparation method thereof, a method for preparing a microchannel plate by using the edge-coated glass and the microchannel plate.
Background
The micro-channel plate has the advantages of small volume, light weight, high resolution, high gain, low noise, low use voltage and the like, and has irreplaceable functions in the technical fields of low-light night vision, space detection, nuclear detection, ultraviolet early warning, medical images and other military and civil photoelectron. Gain and resolution are key core indicators of the microchannel plate, and higher gain and higher resolution are always targets for microchannel plate developers to pursue continuously. Reducing the pore size is the most straightforward and effective way to increase the resolution of the microchannel plate. On one hand, the spatial resolution of imaging can be directly improved by reducing the aperture of the micro-channel plate, so that the detection and identification of weak signals are facilitated; on the other hand, the aperture reduction can increase the number of micropores in the same effective area, reduce the volume resistance, thereby shortening the compensation time of escaping electrons and improving the time resolution of the microchannel plate. Therefore, exploring the lower pore size limit of glass-based microchannel plates, preparing ultra-small pore size microchannel plates has been a hotspot problem in research in this field.
In order to maintain the electron multiplication properties of the microchannel plate, the thickness of the microchannel plate must be reduced while the pore diameter is reduced to meet the optimal aspect ratio, since the electron multiplication properties of the microchannel plate are independent of the absolute value of the single channel diameter and length, and are related to the ratio of length to diameter (aspect ratio). The relationship between the gain maximum value of the micro-channel plate and the length-diameter ratio and the working voltage is proposed by the weya et al, and the relationship u=22α is pointed out that the working voltage and the length-diameter ratio satisfy at the gain maximum value of the micro-channel plate. It can be seen that obtaining maximum gain requires that the microchannel plate thickness meet the optimal aspect ratio. However, the mechanical strength of the microchannel plate is seriously reduced to a certain extent, the microchannel plate is extremely easy to damage during operation and treatment, and the manufacturing difficulty is increased, so that the relatively proper length-diameter ratio parameter is selected as much as possible while the manufacturing difficulty of the process is balanced, and the optimal length-diameter ratio parameter is close to the optimal length-diameter ratio, so that the relatively satisfactory gain of the microchannel plate is obtained. Jin Ge in the study of the double-sided polishing process of the microchannel plate, it is pointed out that when the thickness of the microchannel plate with the aperture of 6 μm is 0.30-0.33 mm, the probability of deformation is extremely high after hydrogen reduction, in order to solve the problem of deformation of the microchannel plate with the aperture of 6 μm, other performances are sacrificed in the manufacturing process, and specific process improvement is specially carried out, so that the problem of deformation is solved to a certain extent, but when the thickness is close to the lower limit of 0.30mm, the probability of deformation is still extremely high. The deformation of the microchannel plate not only affects the mechanical strength, but also deteriorates the resolution and uniformity of the two-dimensional electronic image of the microchannel plate. In the coupling process with CCD, the coupling efficiency is reduced by 10% -20%.
Therefore, with the continuous improvement of the requirements of the device on resolution, imaging definition, detection signal limit and the like, the problem that the performance of the microchannel plate cannot meet the use requirements of the device is more and more remarkable, and especially the problem of reliability caused by the deformation of the microporous array and the reduction of strength due to the reduction of the thickness limited by the length-diameter ratio becomes a key for limiting the performance improvement of the microchannel plate.

in the present embodiment, siO 2 -PbO-Bi 2 O 3 The glass system is a glass system commonly used for microchannel plate cladding, and in order to realize accurate matching with the performance of the microchannel plate cladding, the edge-covered glass designed by the invention adopts SiO 2 -PbO-Bi 2 O 3 The composition is designed and adjusted to obtain high strength, deformation resistant coated glass based on the base glass system. Wherein:
SiO 2 the glass is formed into oxide, is a basic skeleton of a glass structure, is a main component of the edge-covering glass, and has poor chemical stability and low strength when the content is lower than 40.0 percent; when the content exceeds 45%, the high-temperature viscosity of the glass increases, so that the thermal expansion coefficient of the glass increases, and the performance of the glass is not matched with that of the cladding glass. Thus, the first and second substrates are bonded together,SiO 2 the content of (2) is 40.0% -45.0%.
The proper amount of PbO is added into the glass, so that the effect of reducing the melting temperature of the glass can be achieved, but when the content is too high, the grid of the glass can be damaged, and the strength and the chemical stability of the glass are reduced. Therefore, the PbO content is preferably 18.0 to 22.0%.
Bi 2 O 3 Is fluxing agent of glass, and a proper amount of Bi is added into the glass 2 O 3 Can improve the glass forming property and the thermal processing property of the glass, but when Bi 2 O 3 When the content is too high, the strength of the glass may be lowered. Therefore, bi 2 O 3 The content is preferably 7.0 to 8.0 percent.
Al 2 O 3 Is a network intermediate oxide, and Al is added into a glass system in a certain proportion 2 O 3 Due to Al 3+ The glass has larger volume and can enter a glass network, so that the stability of the framework is enhanced, free oxygen in the glass is consumed, and the strength and chemical stability of the glass can be improved. But when Al 2 O 3 When the content is too high, the high-temperature viscosity of the glass can be obviously increased, so that the melting temperature of the glass is increased. Thus, al 2 O 3 The content is 4.0-6.0%.
ZrO 2 And TiO 2 The ionic radius of the glass is larger, and the ionic coordination number is high, so that the glass cannot enter a network and is positioned in a network gap, and the components with large ionic radius are added into the glass, so that the glass structure becomes compact, and the improvement of the strength and chemical stability of the glass is facilitated. However, when the content is too high, the viscosity of the glass increases sharply, which is disadvantageous for melting the glass. Thus, zrO 2 The content of (2) is 4.0-5.0%, tiO 2 The content of (3.0-4.0%).
BaO is a network exosome oxide and is a cosolvent of glass, and proper amount of BaO is added into the glass to improve the glass forming property and the hot working property of the glass, but the content is too high, so that the glass is unstable and the glass is split. Therefore, the BaO content is 5.0% -6.0%.
K 2 O and Na 2 O is an oxide of an external glass networkThe glass is easy to migrate and diffuse in the glass, the high-temperature viscosity of the glass can be reduced, the glass is easy to fuse, and the thermal expansion coefficient of the glass can be changed and regulated. However, too high a content of the two may decrease the chemical stability and strength of the glass. Thus, K is 2 O：3.0％～4.0％，Na 2 O：6.0％～8.0％。
