Description
Technical field
The utility model relates to a kind of low cost multiwire proportional counter electrod-array.
Background technology
Study the reaction between elementary particle, the knowledge of particle properties and interparticle force can be provided.These reactions are conventionally very complicated.Sometimes in a reaction, can produce a hundreds of particle.In order to explain these reactions, scientist often needs to record the track of each particle.It is various photographic processes that this class records conventional method, and the course of work is slow and tired.
Afterwards utility model proportional counter tube to solve the problems of the technologies described above.Proportional counter tube is made up of an anodic wire and a pipe that forms negative electrode.Silk is placed in pipe center, is operated in proportional region.Its principle is: obtain larger electric field intensity by adding high voltage, the electronics that particle produces in pipe internal ionization will be subject to electric field acceleration to obtain enough energy between secondary collision, thereby ionize again other gas molecules, the ionization number (output pulse) of finally collecting will be large more many than initial ionization, but be proportional to initial ionization.Classical proportional counter is as Geiger-Miao Le pipe, is to be contained in by a filament pipe central authorities that diameter is about 1cm to form.Between filament and tube wall, add the high pressure of several kilovolts.Charged particle, through the pipe of inflation, can make gas ionization.In this process, the neutral atom of gas can discharge electronegative electronics, and becomes the ion of positively charged.Under the effect of electric field, electronics is to filament (the being anode) motion of die.The local electric field that approaches filament is very strong, and electronics accelerates greatly, so just have enough energy to make gas ionization, thereby have more electronics to be released, these electronics are accelerated again, so just formed the snowslide of electronics and positive ion.Just because of the motion of electronics and ion, cause that anodic wire produces an electric signal, provides the information that charged particle passes through.Proportional counter tube determines that the precision of particle position is approximately 1cm, i.e. the size of counter tube itself.But this proportional counter precision is not high, is difficult to meet actual needs.
Georges Charpak has been done major reform to it afterwards again.Multiwire proportional counter (the claiming again multiwire proportional chamber) technique functions of Georges Charpak utility model comes from proportional counter tube, its principle of work is: form a unit by accompanying the parallel wire plane of making positive electrode in the middle of two parallel metal nets of making negative electrode, in chamber, fill with inert mixed gas.Between electrode, add high direct voltage, voltage is in proportional region.When high energy charged particles is through multiwire proportional chamber, make the gas atom ionization on path, the electronics that ionization produces forms the ionization propagation of avalanche type nearby in a certain electric field wiry, total electric weight of its electric discharge is proportional to the number of electrons in initial ionization, and the negative pulse that electric discharge forms is proportional to the ionization loss of this particle.Utilize special electronic circuit can determine that incident particle passes the position of chamber, is further made the track of particle by multiple unit.Under electric field and certain gas condition, incident particle causes by ionizing that near anodic wire gas amplifies, the ionization propagation of " snowslide " formula of generation, on this silk, set up a negative pulse, and adjacent anodic wire and cathode filament plane induce the positive pulse of opposite polarity, conventionally be less than 1/10 as for capacity coupled same polarity pulse, and can change electric capacity and make it less.Therefore, use a sensitive amplifier of anticathode pulse, just can make every anodic wire independently incident particle be counted and location as a proportional counter, its locating area taking two anodic wires distance partly as boundary, be on certain silk, to have pulse output, just show to have a particle to be incident in this 1/2 flight lead region.
Only tens square millimeters of the little areas of multiwire proportional chamber, large reaches tens square metres.Anodic wire is commonly used the gold-plated tungsten wire of 20 μ m, 40 μ m diameters, and cathode filament is used beryllium copper silk, gold-plated tungsten wire or the stainless steel wire of 100 μ m left and right conventionally.Gas is commonly used flow type, and the ratio of the most famous is volume is " the magic different gas " that 75.0% argon+24.5% isobutane+0.5% fluorine Lyons 13B1 forms.Each is all connected to amplifier, and connects computing machine and carry out accurate location survey and on-line analysis.
Multiwire proportional chamber has been widely used in particle physics experiment at present, becomes one of main detector of high-energy physics experiment, and many experiments have reached the even scale of several ten thousand anodic wires of use several thousand.In addition, it is also widely used in nuclear physics, uranology and cosmic ray physics, and is progressively being applied to the field such as medical science, biology.
As can be seen here, multiwire proportional chamber has wide application, but it also has weak point: multiwire proportional counter (multiwire proportional chamber) electrod-array is the core component of multifibres radiation detector.For reaching the gain of some strength, the both intensity of electron avalanche, needs to add very high voltage between anode and negative electrode.For increasing the probability that detects high-energy radiation, need to increase area or the volume of detector.
In prior art, the MEMS technology that adopts microelectronics to be combined on silicon chip with micromechanics can go out silicon post array as electrode by deep etching on silicon chip.The large I of each silicon post electrode is less than 20 microns, and spacing can point-devicely be controlled.But due to the restriction of the deep etching degree of depth, the height of electrode is generally less than 500 microns.This need to use expensive micro-process equipment to adopt MEMS technology, and the cost of manufacture of device is higher, has limited it and has promoted the use of.Adopt the detector of MEMS technology simultaneously, as increased the volume of detector, also need to superpose piecewise silicon chip, further improved production cost.And actual use during to the lower field of accuracy requirement, as being integrated into the radiation detector in mobile phone or other handheld device, adopts the detector cost of MEMS technology high at some, can not meet the actual requirement of the field radiation detector lower to accuracy requirement.For this reason, how to reduce proportional counter cost of manufacture, for continuing the technical matters solving in this area.

In the utility model, because the radius of rotor 8 is generally all larger, between several centimetres to several meters, and insulating substrate thickness and width, wire electrode diameter generally only have tens to hundreds of micron, the every layer of wire electrode length error causing when being wound around the rotor of relatively large radius is very little, can ignore; Add in various method steps (2), the wire electrode that can stretch, makes wire electrode have suitable tension stress, ensures that when open and flat opening, each electrode layer powers on polar filament without obvious bending after rotor takes off substrate.In above-mentioned various method steps (2) winding process, can suitably use bonding agent that wire electrode is fixed on insulating substrate, upper and lower two electrode layers power between polar filament horizontal spacing can be by changing wire electrode and rotor axial relative position regulates before winding, for example, often around a circle, wire electrode moves 100 microns along the axis direction of rotor, and can make the upper and lower two electrode layers horizontal spacing between polar filament that powers on is 100 microns.
In the art of this patent, adopt spin-coating method that insulating film material is coated on substrate and after solidifying and forms insulating thin layer, complete the making of insulating substrate; Also can adopt membrane deposition method that insulation film is grown in and on substrate, forms insulating thin layer.Adopt mask structure and utilize metal sputtering technique deposition of conductive metals to be formed on insulating thin layer to the wire electrode conductive strips of wire electrode conduction.
