3. Introduction
The X-ray diffractometer uses accelerated electrons to hit the metal target to generate X-rays, and then irradiates the X-rays on the surface of the material. Due to different crystal structures, the interplanar spacing (d) will be different, and only in X-rays When the incident angle of light irradiation satisfies Bragg's law (Bragg's law) 2dhkl sinθ=nλ (where hkl is the index of each crystal plane), constructive interference will occur. At this time, the detector ( The detector) can receive a strong diffracted beam signal, which is mainly determined by the shape, size and symmetry of the unit cell, so the angles of constructive interference between different materials or different structures are also different.Basically, X-ray diffraction experiments of crystals provide two important information: one is the position of the diffraction peak (2θ), and the other is the intensity of the diffraction front (I). The first piece of information provides information on the shape and size of the crystal's unit cell (ie, lattice parameters); the second piece of information provides information on the types and positions of the constituent atoms within the crystal. With the change of the crystal structure and composition of the material, these two data are different for each crystal, just like the fingerprint of human beings, that is, different crystalline compounds will produce different {2θhkl, I hkl} combined diffraction patterns Therefore, X-ray diffraction analysis can be used to determine which mineral crystal or crystalline material the material belongs to.

- The sample measurement surface should be as flat as possible.
- The electrochemical cell used for on-site analysis needs to be approved by the center.
6. Opening hours
(Open all hours)
7. Precautions for reservation
- After being authenticated by the center, you can register an appointment account online and make an appointment online.
- If there is a need for a long-term on-site electrochemical experiment, the facility administrator must be informed 3 days before the experiment, and an appointment should be made during the time slot (優先 In-situ) in the table above.
- If the time period (優先 In-situ) is not used, it can be used for general operations.
8. Charge Information
- If you do not pay the fee for more than two weeks, you will be notified in advance. If the payment is still in arrears, your teacher and all laboratory personnel will stop entering the HG card machine control.
- The charging method is mainly based on the transfer of funds planned by the Ministry of Science and Technology. You can also apply for a pre-issued receipt with the center and pay in cash through the online payment platform.https://reurl.cc/Q3mbl0。
9. Delegated operation
- For those who need entrusted operation, please contact the equipment administrator to discuss the details of analysis.
