Abstract
A method for economically mass-producing thin plate-shaped microchannel plate, includes: coating the surface of one or more strands of microfiber with a predetermined diameter with a polysilazane or polysiloxane binder; winding one or more strands of binder-coated microfiber onto a bobbin to form a microfiber bundle; curing the binder while the shape of the microfiber bundle is fixed; and slicing the binder-cured microfiber bundle to manufacture the plate.
Claims20
A method for manufacturing microchannel plate wherein the microchannels are parallel and at a certain angle to the surface, comprising steps of:
- (A) coating the surface of one or more strands of microfiber with a predetermined diameter with a polysilazane or polysiloxane binder;
- (B) winding one or more strands of binder-coated microfiber onto a bobbin to form a microfiber bundle;
- (C) curing the binder while the shape of the microfiber bundle is fixed;
- and
- (D) slicing the binder-cured microfiber bundle to manufacture the plate;
- wherein the bobbin includes an area that satisfies the condition of curvature radius R as per the following formula:
- R
- ≥

- Formula
- wherein a is the tolerance threshold value of the distance between the midpoint of a straight line connecting the centers of the cross-sections of both ends of the microchannel and the center of the cross-sectional area at the ½ point of the microchannel,
- b is the thickness of the microchannel plate.
