Description

(54) УСТРОЙСТВО ВЬЩЕЛЕНИЯ ИМПУЛЬСОВ(54) DEVICE FOR THE IMPULSE OF PULSES

Изобретение относитс  к устройствам временного выделени  импульсов в услови х фона с переменной интенсивностью и может быть использовано в измеритеньной аппаратуре, в частности в аппаратуре дл  измерени  ионизирующих излучений.The invention relates to a device for the temporary separation of pulses in the background of a variable intensity background and can be used in measuring equipment, in particular in equipment for measuring ionizing radiation.

Известно устройство выделени  импульсов, содержащее дискриминатор с регулируемым уровнем 1 В этом устройстве при переменной интенсивности фона и уровне информационных импульсов ниже уровн  фона выделение импульсов путем установки уровн  дискрим1шации выше уровн  фона невозможно.A device for selecting pulses is known, which contains a discriminator with an adjustable level 1 In this device, with a variable background intensity and level of information pulses below the background level, it is impossible to select pulses by setting the discriminating level above the background level.

Наиболее близким к изобретению по своей технической сущности  вл етс  устройство выделени  импульсов, содержащее элемент совпадений и не менее двух информационных каналов в каждом из которых содержитс  усилитель и нормализатор 2.Closest to the invention in its technical essence is a pulse extraction device containing an element of coincidence and at least two information channels in each of which contains an amplifier and a normalizer 2.

Однако это устройство имеет недостатоодую эффективность.выделени  информационных импульсов при больших средних скорост х поступлени  импульсов фона, большом времени измерени  и малом количестве ш формадионных импульсов.However, this device has a lack of efficiency. It does not emit information pulses at high average rates of arrival of background pulses, long measurement time and a small number of w-shaped pulse.

Целью изобретени   вл етс  повышение эффективности выделени  информацио1шых 1улпульсов .The aim of the invention is to increase the efficiency of the selection of informational pulses.

Дл  этого Е устройство вьщелени  импульсов, содержащее элемент совпаден ий и не менее двух информационных каналов, в каждом нз которь х содержитс  усилитель и нормализатор, в каждый канал введены дискриминатор, включеннь Й между усилителем и нормализатором, и измеритель скорости счета импульсов, вход которого подключен ко входу элемента совпадений , si выход соединен со входом дискриминатора .For this, E is a pulse pulsing device containing an element of coincident and at least two information channels, each of which contains an amplifier and a normalizer, a discriminator is inserted into each channel, connected between the amplifier and the normalizer, and a pulse count rate meter whose input is connected to the input of the match element, si output is connected to the input of the discriminator

На фиг. I приведена схема устройства; на фиг. 2 показана форма сигнала.FIG. I shows a diagram of the device; in fig. 2 shows the waveform.

Устройство вьщелени  импульсов содержит усилители 1 и 2, дискрим1гааторы 3 и 4, нормализаторы 5 и 6, измерители 7 и 8 скорости счета , элемент 9 совпадений и элемент 10 установки начального уровн  дискрим1шации, входные mmibi 11 и 12,причем шина 11 через включетThe pulse pulsing device contains amplifiers 1 and 2, discriminators 3 and 4, normalizers 5 and 6, meters 7 and 8 counting speed, coincidence element 9 and element 10 for setting the initial level of discriminator, input mmibi 11 and 12, with bus 11 through
