KOBoro фильтра 18, a посредством резистора 19 - со вторым конденсатором токового фильтра 20, а также с кабелем 21 токового сигнала, подвод щим ко входу токового усилител 22.KOBoro filter 18, a by means of a resistor 19, with the second capacitor of the current filter 20, as well as with the cable 21 of the current signal supplied to the input of the current amplifier 22.
Элемент обратной св зи 23 соединен со входом и выходом токового усилител 22. К выходу токового усилител 22 присоединен индикатор 24 среднего тока ионизационной камеры .The feedback element 23 is connected to the input and output of the current amplifier 22. The indicator 24 of the average current of the ionization chamber is connected to the output of the current amplifier 22.
Устройство работает следующим образом. После помещени детектора в нейтронном нотоке между электродами 1 и 2 генерируютс импульсы электрического зар да, вызывающие импульсы напр жени , на емкости детектора , принимаемые посредством первичной обмотки входного трансформатора 4. В интересующем нас при импульсной работе диапазоне частоты электрод напр жени 2, один конец первичной обмотки и середина вторичной обмотки входного трансформатора 4 замыкаютс на массу системы посредством конденсаторов 5 и 6. Импульсы напр жени передаютс при помощи входного трансформатора 4, симметрического кабельного канала 10 и согласующего трансформатора 11 в широкополосный усилитель 12 и кабельную линию 13, а после усилени в конечном усилителе 14 - в дискриминатор 15 и интегратор импульсов 16, который генерирует сигнал, пропорциональный частоте импульсов детектора. Измер емое значение отсчитываетс при помощи измерител частоты импульсов 17. Высокое сопротивление изол ции между обмотками трансформатора 4 и трансформатора 11 и массой системы вл етс причиной того, что весь средний ток, вызываемый происход щей в камере ионизацией, протекающий от сигнального электрода 1 через обмотки входного трансформатора , центральные провода симметрического кабельного канала 10, а затем через первичную обмотку согласующего трансформатора 11, резистор 19 и кабельную линию 21, 5 поступает в токовый усилитель 22. Этот ток пропорционален нейтронному потоку в детекторе в диапазоне его больших значений, при которых вли ние тока, происход щего от фона , вызванного альфа-распадом, может неThe device works as follows. After the detector is placed in a neutron note between electrodes 1 and 2, electric charge pulses are generated causing voltage pulses on the detector capacitances received by the primary winding of the input transformer 4. In the frequency range of interest, voltage electrode 2, one end of the primary the windings and the middle of the secondary winding of the input transformer 4 are shorted to ground of the system by means of capacitors 5 and 6. The voltage pulses are transmitted using the input transformer 4, sim etricheskogo raceway 10 and the matching transformer 11 to a broadband amplifier 12, and the cable line 13 and after amplification in the end amplifier 14 - at the pulse discriminator 15 and an integrator 16 which generates a signal proportional to the frequency of the detector pulses. The measured value is measured using a pulse frequency meter 17. The high insulation resistance between the windings of transformer 4 and transformer 11 and the system mass is the reason that all the average current caused by ionization in the chamber, flowing from the signal electrode 1 through the windings of the input electrode transformer, central wires of the symmetrical cable channel 10, and then through the primary winding of the matching transformer 11, the resistor 19 and the cable line 21, 5 enters the current amplifier 22. This the current is proportional to the neutron flux in the detector in the range of its large values at which the influence of the current resulting from the background caused by alpha decay may not
