Description

Technical Field

[0001] The invention relates to the technical field of neutron and particle physics experimental equipment, in particular to an integrated adjustable neutron conduit glass conduit splicing platform. Background Art

[0002] Neutron spectrometers play an important role in the study of the microstructure and dynamics of matter. Among them, neutron scattering technology studies the properties of matter by using spallation neutrons produced by bombarding the target with a high-energy proton beam. These neutrons are transmitted to the spectrometer hall through a neutron guide and eventually reach the sample. The inside of the neutron guide is coated with a Ni / Ti super-mirror coating, which can reflect during neutron transmission, thereby efficiently transmitting neutrons from the moderator to the center of the sample far away from the source. This technology significantly reduces beam losses, ensures the neutron flux at the sample, and greatly improves the working efficiency of the spectrometer.

[0003] However, the splicing quality of neutron guide tubes, especially the glass guide tube part, has a direct impact on the neutron transmission capacity, which in turn affects the final neutron flux and spectrometer performance. Although the existing neutron guide tube splicing technology has made some progress, there are still some significant problems.

[0004] For example, although some existing splicing technologies provide adjustable support components to facilitate the adjustment of the coaxiality and position of the neutron tube connection, these technologies mainly focus on the adjustment of the support components, and do not provide an integrated solution to complete the assembly of the entire glass tube.

[0005] On the other hand, there are some integrated glass conduit splicing platforms on the market, which can complete the assembly of glass conduits in a centralized manner and provide certain adjustment capabilities. However, the fixtures of these platforms are fixed in size and cannot meet the needs of glass conduits with different opening sizes, so their scope of application is limited.

[0029] Embodiment 1: In this embodiment, the basic structure and functions of the splicing platform will be described in detail.

[0030] The platform comprises a mounting base plate 1, on which are arranged a left end support mechanism 2, a linear guide rail assembly 3, a height support adjustment mechanism 4, a gear rack transmission mechanism 5 and a right end support mechanism 6. These mechanisms jointly support an inner sample assembly 7, and a clamping plate assembly 8 is arranged on the inner sample assembly 7 for fixing the glass substrate assembly.

[0035] First, the operator places the glass substrate assembly on the inner sample assembly 7 and fixes it by the clamping plate assembly 8. This step is the key to ensure the stability and accuracy of the subsequent splicing process.

[0036] Next, the height of the pressing plate assembly 8 is adjusted by the height support adjustment mechanism 4 to ensure that it can be properly supported during the splicing process. This step is crucial to prevent the glass conduit from shifting or being damaged during the splicing process.

[0037] Then, the position of the right end support mechanism 6 is adjusted by the gear rack transmission mechanism 5 to put the glass conduit in the best splicing position. This precise adjustment capability ensures the accuracy and quality of the splicing.

[0038] When the glass tubes are spliced, the spliced ​​glass tubes can be taken out through the left-end supporting mechanism 2 and the right-end supporting mechanism 6 to complete the entire splicing process.
