WIPO Patent Application WO/2017/039561
Kind Code:
A1
Abstract:
This application is an improvement of current in use traditional X-ray diffractometer, and has new sample holders, new X-ray diffraction spectrums recording system, and new method to analyze the recorded X-ray diffraction spectrum data. This new 360° All Around Turn X-Ray Diffractometer let samples turn around in X-rays 360° all around, and records the diffraction spectrum, unlike current in use traditional X-ray diffractometers that scan samples in limited less than 180° angles.

BACKGROUND OF THE INVENTION

Not applicable. BRIEF SUMMARY OF THE INVENTION

This application is an improvement of current in use traditional X-ray diffractometers, and has new sample holders, new X-ray diffraction spectrums' recording systems, and new methods to analyze the recorded X-ray diffraction spectrum data. This new 360° All Around Turn X-ray diffractometer let samples turn around in X-rays 360° all around, and records the diffraction spectrums, unlike current in use traditional X-ray diffractometers that scan samples in limited less than 180° angles. The current in use X-ray diffractometer's spectrums do not allow the wave form analysis method as illustrated in Dr. Manly' s book "Wave Form Analysis" to decompose the complex wave forms into simple wave forms. To use the wave form analysis method the recorded wave form must have 360° or more angles' spectrums. More than 180° but less than 360° complex wave forms can only be incompletely decomposed, and thus the obtained simple wave forms are incomplete. The current in use traditional X-ray diffractometers only scan samples in less than 180° turn angles, thus the recorded X-ray diff action spectrums can not be separated into simple wave forms by using wave form analysis method. Accordingly it is very difficult to analyze the complex wave forms from current in use X-ray diffractometers, and to relate these spectrum data to sample

i

structures. In certain circumstances the recorded X-ray diffraction spectrum can not be explained.

Each electron concentrated peak area is placed a slit and a film. Thus the sample X-ray diffraction spectrums are recorded.

DETAILED DESCRIPTION OF THE INVENTHON

The 360° All .Around Turn X-ray Diffractometer scans samples in 360° or more angles, let samples to be turned around in X-rays and records the samples' diffraction spectrum. The wave from analysis method can be used to decompose the recorded complex wave forms into simple wave forms, thus makes it feasible and easy to analyze the recorded X-ray diffraction spectrums. The 360° All Around Turn X-ray Diffractometer includes, but not limited to: single crystal X-ray diffractometer, powder X-ray diffractometer, and small angle X-ray diffractometer. The 360° All Around Turn X-ray Diffractometer contains X-ray source, cuvet, sample holder, plate, and spectrum recording systems. Unlike current in use traditional X-ray diffractometers, The 360° All Around Turn X-ray Diffractometer has the sample holder that can be turned around 360° in X-rays. In addition The 360° All Around Turn X-ray Diffractometer has additional recording systems. These additional recording systems are: plate to record the sample X-ray diffraction spectrums when the samples are scanned hi stable conditions. Then the slits are placed at the electrons concentrated area located at the X-ray diffraction spectrums on the plate. The plate is put away from the X-ray path. The particles counter systems are put behind the slits to allow the diffracted electrons to reach the counter systems. When the samples are turned around in X-rays, the counter systems count the reached dif&acted electrons and record them, thus record the 360° or more angles' scan X-ray diffraction spectrum. Another recording system is the film recording systems that are placed at the electrons concentrated areas located at the X-ray diffraction spectrum to record the reached diffracted electrons. When the samples are turned around, the films are turned and record the dif&acted electrons. These recorded X-ray diffraction spectrums record the samples' 360° or more angles turn X-ray diffraction spectrum.

When single crystals are scanned, samples are put in the cuvet. By selecting the thinner or thicker lid, the sample is put in the cuvet and placed tightly against the cuvet sides. The sample can not slide, or turned in the cuvet. The sample cuvet is put in sample holder in the direction such that the 1 axis side can be turned and scanned. Then the sample is turned, scanned, and the X-ray diffraction spectrums are recorded. The cuvet is brought out of the sample holder. The cuvet is turned in another direction and put in the sample holder. This time the m axis side is turned, scanned, and the X-ray diffraction spectrums are recorded. The cuvet is brought out of the sample holder. The cuvet is turned again in the third direction, and put in the sample holder. This time the n axis side is turned, scanned, and the X-ray diffraction spectrums are recorded. By analyzing all these 1, m, n axis sides' x-ray diffraction spectrums, the single crystal sample structure parameters are obtained.

When powder samples are scanned, only one cuvet axis side is turned, scanned, and the X-ray diffraction spectrums are recorded. The powder samples' 1 axis side, m axis side, and n axis side scan X-ray diffraction spectrums are same.

DETAILED DESCRIPTION OF ( THE INVENTION

At the last paragraph add the following paragrapg:

Another way to scan crystal sample is: to piit X-ray source, sample holder, slit, and the particle counter

system at the same rod. The sample holder is kept stable, while the x-ray source, the slit, and the particle counter system are turned 360° with the rod. Thus record the sample X-ray diffraction complex wave forms.The recording system could also be the film recording system.. The films are located at thepe periphery of a circle centered at the sample holder. The j radius of the film to the sample holder is larger thanb the radius of the slit to sample holder. The X-ray source turned around 360°, while the sample holder is kept stable. The films at the periphery circle recorded s the sample x-ray diffraction complex wave forms.

DETAILED DESCRIPTION OF THE INVENTION At the last paragraph add the following paragraphs:

This instrument machine specification includes the scanning crystal samples vertically, or tilted, that is to put the diff action spectrum plate vertically, and turn the sample cuvet around vertically. To tilt the plate and sample cuvet to scan, or scan vertically are going to have the same diffraction spectrums as to scan the sample in the process as described in the pages 1-3.

To enhence the ability of this instrument machine to seperate the complex X-ray wave forms to simple wave forms an U shape electromagnetic iron is placed at the two ends of the spectrum plate. High voltage is applied at the electromagnetic iron while scanning and recording the X-ray diff action spectrum.
