Abstract
The performance test method of multi-wire hyperbar proportional counting tube is operated by adopting the folloiwng steps: when every wire is mounted, hanging a weight whose weight is identical to that of wire so as to make tension of every wire attain uniformity; changing internal connection of anode wire in proportional counting tube into external connection; before connection connecting every wire with an external potentiometer, respectively applying identical working high-pressure to every wire and measuring out signal output amplitude of every wire, this moment, the measured output amplitudes can be different; respectively regulating potentiometer connected with every wire to make signal output amplitudes of every wire identical; after the satisfactory test result is obtained, these wire are connected together so as to implement said invention.
Description
Technical field
The present invention relates to a kind of adjustment method of astronomical instrument, particularly the performance adjustment method of multifibres hyperbar proportional counter tube.
Background technology
At high-energy physics, nuclear physics and space astronomy field, the quality of detection instrument performance for the realization of accurate surveying of trying to achieve the celestial body target and scientific thought, plays crucial effect.In the observation work of carrying out the space astronomy hard X ray, very high to the performance requirement of space instrument, must accomplish: good stability, energy resolution height, highly sensitive.Proportional counter tube is the important component part in the detection instrument, and the quality of its performance plays a part crucial to the performance of whole instrument.Proportional counter tube window useful area 500cm
2, operating air pressure is 3 kilograms a xenon-133 gas.Anodic wire divides totally two ten three of four layer of five rows, and wherein nine is the anode signal silk, and 14 of bottom surface and two sides are the anticoincidence silk.By traditional method be; Nine of signal silks are linked together in proportional counter tube inside, and anticoincidence 14 rhizoids link together in proportional counter tube inside, respectively are one the tunnel to export separately.The result of this kind connected mode is that the proportional counter tube energy resolution is relatively poor.The relatively poor reason of energy resolution is: every rhizoid elasticity after assembling is variant, makes every rhizoid impedance difference over the ground, and this species diversity superposition finally makes the proportional counter tube energy resolution reduce together.
Summary of the invention
What we will observe is 20-100KeV universe hard X ray.The applicant determines to change traditional monofilament proportional counter tube, and cast is multifibres, large tracts of land, hyperbar proportional counter tube cast.The invention task provides a kind of new adjustment method, to overcome the every rhizoid of hyperbar proportional counter tube in elasticity difference, the different disadvantage of earth impedance, obtains the effect that improves sensitivity.
In order to overcome the shortcoming of traditional structure and adjustment method, the present invention takes the way of multichannel output to improve the proportional counter tube performance.Specific practice is to operate according to the following steps:
When each rhizoid of assembling, hang a weight that weight is identical, make the tension force of every rhizoid reach consistent as far as possible
Change anodic wire into externally connection by inner connection of original proportional counter tube
The external potentiometer of every rhizoid adds identical working voltage at every rhizoid respectively before connection, measures the signal output amplitude of every rhizoid, and the output amplitude of measuring this moment can be different
Debug the potentiometer that every rhizoid joins respectively, make the signal output amplitude of every rhizoid identical
After obtaining satisfied test result, they are linked together.
This change multifibres is the method for monofilament, has improved the energy resolution of proportional counter tube significantly, has improved the performance of detection instrument, has satisfied the requirement of our problem observation.
