Problems solved by technology

Because the irradiation device must meet the requirements of the centering of the sample and the detector, and the centering of the sample and the incident neutron beam, the requirements for the centering accuracy, repeat positioning accuracy, and installation accuracy of the irradiation device are relatively high, that is, for The processing accuracy and installation accuracy of the main mechanical devices of the irradiation device are high, and the current irradiation device can only be used for one-time irradiation of the sample, without the adjustment function, and can only conduct sample irradiation analysis at a fixed angle and a fixed path

Abstract

The invention provides an irradiation sample automatic adjusting and detecting device. A worktable of the device is provided with a sample table adjusting rack used for adjusting positions of samples and a detector adjusting rack used for monitoring radiation conditions of the samples. By means of the adjusting and detecting device, the positions of the samples in the radiation environment can be automatically adjusted, the radiation conditions of the samples can be detected, and the adjusting and detecting process is completely automatic. The device has the function of controlling the sizes and the positions of the samples and the detection angle and a path of a detector, the samples can be irradiated and detected at a time, and multi-angle multi-position irradiation and detection of the same sample can be completed for many times.

Description

technical field [0001] The invention belongs to the field of particle beam irradiation devices, in particular to an automatic adjustment detection device for irradiated samples. Background technique [0002] Currently, samples irradiated in a radiation environment (such as neutron radiation) are generally irradiated by installing an irradiation device in the target chamber, and the position of the irradiation device is mainly guaranteed by the processing reference and installation reference of the mechanical device. Because the irradiation device must meet the requirements of the centering of the sample and the detector, and the centering of the sample and the incident neutron beam, the requirements for the centering accuracy, repeat positioning accuracy, and installation accuracy of the irradiation device are relatively high, that is, for The machining accuracy and installation accuracy of the main mechanical devices of the irradiation device are high, and the current irrad...
