Problems solved by technology

[0003] In the prior art, the back-end rough collimator support is rarely involved, and it is mostly supported by a simple frame. For neutron optical application equipment, the installation accuracy is often high, and the shape of the back-end rough collimator is mostly prism columnar Structure, the simple support frame makes the installation and adjustment of the rear rough collimator extremely difficult

Embodiment Construction

[0029] The specific implementation manner of this embodiment is described in detail below in conjunction with accompanying drawing of description:

[0030] In this embodiment, "front" refers to the direction close to the sample, and "rear" refers to the direction away from the sample. "Up", "Down", "Left", and "Right" respectively refer to the rear end surface of the rear-end rough collimator bracket as the main view, and the upper side, lower side, and left side of the rear-end rough collimator bracket and the right side. Correspondingly, "horizontal" refers to the left and right directions of the rear rough collimator support; "longitudinal" refers to the front and rear directions of the rear rough collimator support.

[0031] Such as Figure 1-7 As shown, a rear-end rough collimator bracket for neutron scattering, the rear-end rough collimator bracket mainly includes a fixed base 1, a vertical moving plate 2, a translational Plate 3 and upper end bracket 4, the upper end...

Abstract

The invention relates to the field of science and technology of neutron scattering, in particular to a rear-end rough collimator support for neutron scattering and an installation and debugging method. The rear-end rough collimator support mainly comprises a fixing base, a vertical moving plate, a horizontal moving plate and an upper-end support which are installed sequentially from bottom to top,wherein the upper-end support is installed on the upper end surface of the horizontal moving plate through screws, the vertical moving plate and the horizontal moving plate are fastened through a vertical pull plate assembly, the fixing base and the vertical moving plate are connected through vertical adjusting mechanisms, and horizontal adjusting mechanisms are installed on the vertical moving plate and the horizontal moving plate. The three-dimensional independent adjustment capability is obtained through the independent horizontal adjusting mechanisms and vertical adjusting mechanisms, andthe installation verticality can be adjusted through the vertical pull plate assembly. The rear-end rough collimator support is simple in structure and convenient to manufacture and install and has the shape identical to the vertical projection of a rear-end rough collimator, all that is required for installation adjustment is the space under the rough collimator of the support, and small space is occupied on the whole.

Description

technical field [0001] The invention relates to the field of neutron scattering science and technology, in particular to a back-end rough collimator support for neutron scattering and an installation and debugging method. Background technique [0002] In the neutron scientific research experiment, in order to analyze the information such as the crystal structure and magnetic structure of the sample, several detector arrays need to be installed around the sample to receive the neutrons after the sample is irradiated, and provide technical support for subsequent data acquisition and data analysis . However, neutrons have a large loss of flux when propagating in the air and are greatly affected by stray neutrons. Therefore, it is necessary to install a rear-end rough collimator between the sample and the detector to obtain better beam quality. The core component of beamlet engineering and neutron scientific research devices, and the back-end rough collimator bracket is also ve...
