Problems solved by technology
[0004] In the existing neutron scattering experiment process, the experimental equipment can only conduct one experiment at a time. After a sample is tested, it is necessary to turn off the neutron beam, disassemble and install new samples, and shield the wall switch. Low, a great waste of both expensive neutrons and user time

Embodiment 1
[0039] Embodiment 1 provides a sample replacement device for neutron scattering experiments.
[0040] The sample replacement device includes a sample box storage device, a neutron scattering beam window and a sample box moving device.
[0041] The sample box storage disk is used to store samples that need to be subjected to neutron scattering experiments, and the samples can be in the form of liquid, powder, solid, etc. The samples are contained in the corresponding sample boxes, and the sample box storage disc is used to store the sample boxes containing the samples. The sample box storage tray has at least two sample box storage positions, so more than two sample boxes can be stored.

The application discloses a sample replacing device for a neutron scattering experiment. The device comprises a sample-box-storing device, a neutron scattered beam window, and a sample-box-moving device. A sample-box-storing disc comprises at least two sample-box-storing places for storing sample boxes containing samples. The neutron scattered beam window is used for carrying out the neutron scattering experiment on the samples placed in the window and is provided with sample-box-arranging places for arranging the sample boxes. The sample-box-moving device comprises a drive unit and a chuck assembly, wherein the drive unit drives the chuck assembly to pick the sample boxes up and to transfer the sample boxes between the sample-box-storing device and the neutron scattered beam window. When the neutron scattering experiment is carried out, through the device, the sample boxes can be moved through the sample-box-moving device, thereby enabling at least two samples to be subjected to the neutron scattering experiment. Compared with the prior art, the experiment efficiency is improved, and the experiment cost is saved.
