Description
(54) КОЛЛИМАТОР ДЛЯ УСТРОЙСТВА РАДИАЦИОННОГО КОНТРОЛЯ(54) COLLIMATOR FOR RADIATION CONTROL DEVICE
II
Изобретение относитс к радиационной технике, в частности к радиационному неразрушающему контролю изделий.The invention relates to radiation engineering, in particular, to radiation nondestructive testing of products.
Известно устройство дл радиационного контрол изделий, содержащее источник ионизирующего излучени с коллиматором, привод дл возвратнопоступательного перемещени источника относительно контролируемого издели , детектор излучени с регистрирующим устройством }.A device for radiation monitoring of products is known, which contains a source of ionizing radiation with a collimator, a drive for reciprocally moving the source relative to the product under test, a radiation detector with a recording device}.
Недостатком устройства вл етс больша масса подвижных элементов, что ограничивает скорость сканировани и существенно затрудн ет контроль издели в технологическом потоке .The drawback of the device is a large mass of moving elements, which limits the scanning speed and significantly complicates the control of the product in the process stream.
Известно также устройство дп радиационного контрол изделий, содержащее неподвижный относительно контрЪлируемого издели многощелевой коллиматор , содержащий расположенные в р д пластины поглотителей .2J.It is also known a device dp for radiation control of products, containing a multislit collimator stationary relative to the product being controlled, containing a plate of absorbers arranged in a row .2J.
Недостатком данного устройства вл етс зависимость (модул ци ) потока излучени в Сформированном многоще- левым коллиматором пучке от линейных размеров источника в направлении его перемещени , привод ща к увеличению погрешности контрол .The disadvantage of this device is the dependence (modulation) of the radiation flux in the beam formed by the multistage collimator on the linear dimensions of the source in the direction of its movement, leading to an increase in the control error.
Цель изобретени - уменьшение погрещности при контроле изделий с помощью прот женности источника.The purpose of the invention is to reduce the incidence in the control of products with the help of the source length.

Поставленна цель достигаетс тем, что многощелевой коллиматор устройства дл радиационного контрол изделий , содержащий расположенные в р д пластины поглотителей, снабжен втоts рым р дом пластин, расположенных параллельно лластинам первого р да и сдвинутых относительно пластин первого р да на ширину коллимационной щели, а ширина пластин равна ширине This goal is achieved by the fact that a multislit collimator of a device for radiation control of products containing absorber plates arranged in a row is provided with a second row of plates arranged parallel to the first row plates and shifted relative to the first row plates by the width of the collimation slit, and the width of the plates equal to the width
20 щели между ними.20 gaps between them.
