Abstract
The utility model discloses a kind of mounting seat of image intensifier Sandwich MCP, including the upper mounting ring (1) and lower mounting ring (2) for installing Sandwich MCP (5), and the spring pressuring ring between Sandwich MCP (5) and upper mounting ring (1), the spring pressuring ring is L-shaped split ring trim ring (4), and upper mounting ring (1) is pressed in the top of L-shaped split ring trim ring (4).The utility model is installed after MCP using the L-shaped spring pressuring ring (4) after improving, and it is excessive to solve trapezoidal spring pressuring ring pressure, is caused MCP to rupture or the problem of electrode layer is damaged, is substantially increased the yields of double MCP image intensifiers manufactures.
Description
Technical field
The utility model belongs to image intensifier technical field, more particularly to a kind of installation of image intensifier Sandwich MCP
Seat.
Background technology
Gleam image intensifier is used as electron multiplier using microchannel plate (MCP).In order to improve the gain of image intensifier, have
When generally require to carry out cascade-multiplied using two panels MCP.Two panels MCP installation is typically that MCP is sequentially placed into MCP mounting seats
On, MCP is then compressed by using split ring trim ring.
Because MCP is a kind of cavernous glass fibre array, hole wall is relatively thin, easily damages.Therefore when existing spring pressure
When circle is applied to the MCP that two panels is cascaded, because the pressure of spring pressuring ring is excessive so that be applied to the pressure between two panels MCP
It is corresponding excessive, so often damage the surface electrode layer contacted with each other between two panels MCP.Once the electrode layer is damaged,
Field emission will be so caused, image intensifier is scrapped, the yields of image intensifier manufacture is reduced.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of mounting seat of image intensifier Sandwich MCP.It is described
Mounting seat substitutes original trapezoid-shaped openings spring pressuring ring using L-shaped split ring trim ring, solves trapezoid-shaped openings trim ring pressure mistake
Caused by contact surface electrode is damaged between MCP caused by big the problem of Flied emission.
The technical solution of the utility model is as follows：A kind of mounting seat of image intensifier Sandwich MCP, including for installing
The upper mounting ring 1 of Sandwich MCP 5 and lower mounting ring 2, and the spring pressure between Sandwich MCP 5 and upper mounting ring 1
Circle, the spring pressuring ring is L-shaped split ring trim ring 4, and upper mounting ring 1 is pressed in the top of L-shaped split ring trim ring 4.
The upper mounting ring 1 is shaped as zigzag or similar zigzag.
The material of the L-shaped split ring trim ring 4 is stainless steel (1Ni 18Cr Ti9).
The size of the L-shaped split ring trim ring 4 is：The depth-width ratio in L-shaped section is 1:1.3~1.5.
The utility model using L-shaped split ring trim ring be hardly damaged contact surface principle be：MCP is to lean on split ring
Pressure produced by trim ring deformation is compressed, and under same deformation condition, the pressure of L-shaped split ring trim ring is more trapezoidal to be opened
The pressure of mouth spring pressuring ring is small, so pressure is hardly damaged MCP after reducing., will in order to be supported the use with L-shaped split ring trim ring
Upper mounting ring 1 is changed to zigzag shape by original sheet.
Compared with prior art, the utility model has the advantages that：The utility model is using the L-shaped bullet after improving
Spring trim ring 4 is installed after MCP, and it is excessive to solve trapezoidal spring pressuring ring pressure, causes MCP to rupture or the problem of electrode layer is damaged,
Substantially increase the yields of double MCP image intensifiers manufactures.
Brief description of the drawings
The mounting structure schematic diagram for the double MCP of image intensifier that Fig. 1 the utility model is provided；
Fig. 2 is the partial enlarged drawing of B location；
Fig. 3 is the cross-sectional view of L-shaped split ring trim ring；
Fig. 4 is the plan of L-shaped split ring trim ring；
Marked in figure：Mounting ring under the upper mounting rings of 1-, 2-, the trapezoidal spring pressuring rings of 3-, 4-L shape split ring trim rings, 5- is micro-
Channel plate (MCP).
Embodiment
The technical solution of the utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1 to 4, the mounting seat of the image intensifier Sandwich MCP, including for installing Sandwich MCP 5
Upper mounting ring 1 and lower mounting ring 2, and the spring pressuring ring between Sandwich MCP 5 and upper mounting ring 1, the spring
Trim ring is L-shaped split ring trim ring 4, and upper mounting ring 1 is pressed in the top of L-shaped split ring trim ring 4.L-shaped split ring trim ring 4
Size is：The depth-width ratio in L-shaped section is 1:1.4.
The similar zigzag of shape of upper mounting ring 1, the material of L-shaped split ring trim ring 4 is stainless steel (1Ni 18Cr
Ti9)。
The mounting seat is when installing double MCP 5, and erection sequence is similar with original erection sequence.I.e. by two panels MCP5 according to
It is secondary to be placed in the lower mounting ring 2 of image intensifier shell, L-shaped split ring trim ring 4 is installed again in two panels MCP5 top.L-shaped is opened
Mouth spring pressuring ring 4 is fixed in mounting ring 1, and MCP is fixed on into MCP lower mounting ring 2 and upper installation by the elastic force of itself
Between ring 1.The output electrode and input electrode of lower mounting ring 2 and upper mounting ring 1 also simultaneously respectively as MCP.
Claims (4)
1. a kind of mounting seat of image intensifier Sandwich MCP, it is characterised in that including for installing Sandwich MCP (5)
