Description
Technical field
The utility model relates to electron beam measuring instrument field, particularly relates to a kind of electronic beam current section and intensity distribution measurement instrument.
Background technology
Prior art adopts on glass sheet to observe or measurement electron beam; Because its border is very not clear, and differentiate beam intensity difficulty from color and have quantitative description, we devise a kind of electronic beam current section and intensity distribution measurement instrument for this reason.
Summary of the invention
The utility model uses glass sheet to be difficult to the problem of quantitative description electron beam to solve tradition, and provides a kind of electronic beam current section and intensity distribution measurement instrument.
For achieving the above object, provide a kind of electronic beam current section and intensity distribution measurement instrument, comprise diaphragm sheet and copper conductor, be provided with dead ring, be provided with Faraday cylinder below dead ring below diaphragm sheet, Faraday cylinder lower outer is surrounded by insulator foot to the utility model; Faraday cylinder side is provided with the screw in order to fixed copper wire, is lined with pad between screw and Faraday cylinder; Copper conductor side is provided with line amplifier, and line amplifier side is connected with computing machine, and insulator foot side is provided with driving shaft, and driving shaft side is connected with stepper motor; Described diaphragm sheet centre bit is equipped with an aperture.
The diameter of the aperture of described diaphragm sheet center is 0.1mm.
Described dead ring is porcelain ring.
The beneficial effects of the utility model are: a kind of electronic beam current section described in the utility model and intensity distribution measurement instrument, can direct vision quantitative description electronic beam current section and intensity distributions.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electronic beam current section described in the utility model and intensity distribution measurement instrument;
Wherein: 1-diaphragm sheet; 2-dead ring; 3-Faraday cylinder; 4-insulator foot; 5-pad; 6-screw; 7-line amplifier; 8-copper conductor; 9-computing machine; 10-driving shaft; 11-stepper motor.
Embodiment
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
A kind of electronic beam current section and intensity distribution measurement instrument, comprise diaphragm sheet 1 and copper conductor 8, and diaphragm sheet 1 is provided with dead ring 2 below, and dead ring 2 is provided with Faraday cylinder 3 below, and Faraday cylinder 3 lower outer is surrounded by insulator foot 4; Faraday cylinder 3 side is provided with the screw 6 in order to fixed copper wire 8, is lined with pad 5 between screw 6 and Faraday cylinder 3; Copper conductor 8 side is provided with line amplifier 7, and line amplifier 7 side is connected with computing machine 9, and insulator foot 4 side is provided with driving shaft 10, and driving shaft 10 side is connected with stepper motor 11; Described diaphragm sheet 1 centre bit is equipped with an aperture.
The diameter of the aperture of described diaphragm sheet 1 center is 0.1mm.
Described dead ring 2 is porcelain ring.
Stepper motor 11 drives whole measuring instrument to operate; Stepper motor 11 drives the aperture of diaphragm sheet 1 center to distinguish inswept bundle spot length by length at X to Y-direction; The electric current that Faraday cylinder 3 accepts is to restrainting the beam intensity of spot through this aperture; Because aperture is very little, what accept is weak current, need to be input in computing machine 9 by signal and to carry out data processing and drawing, finally export beam profile and intensity distributions situation through line amplifier 7.
