Embodiment

Fig. 1 illustrates the XRD device 100 according to the utility model one embodiment, and it comprises sample stage 110 for placing sample and for the x-ray source 120 to sample irradiation X ray.

As shown in Figure 1, sample stage 110 can be the sample stage that this area is commonly used, the disc structure be such as made up of stainless steel.In embodiment of the present utility model, sample stage 110 is also provided with the first electrode 112.Such as, the first electrode 112 can be Copper Foil or copper coin, and it also can have circular configuration, and is placed on sample stage 110.In certain embodiments, can be kept apart by insulating material between the first electrode 112 and sample stage 110, to avoid the signals such as electrostatic on sample stage 110 to the interference of the signal on the first electrode 112.First electrode 112 can be connected to power supply by the through hole of wire on sample stage 110, and this will describe below in further detail.

In further embodiments, the first electrode 112 can be omitted, and sample stage 110 itself can be such as made up of copper coin and be used as the first electrode.Like this can reducing portion number of packages, and make the structure of XRD device simpler.

Sample 114 can be placed on the first electrode 112.In one embodiment, sample 114 can be adhered on the first electrode 112 by conductive paste.Conductive paste can promote the excellent electric contact between sample 114 and the first electrode 112, and can also keep fixing to make it during X-ray measurement by fixed sample 114.The upper surface of sample 114 can be wired to power supply, and this also will describe below in further detail.

X-ray source 120 is for launching X ray 122, and X ray 122, after beam adjuster 124 collimates, is irradiated on sample 114 at a certain angle.Although not shown, x-ray source 120 can be arranged on the track (not shown) around sample stage 110, thus when x-ray source 120 is along rail moving, can change the incident angle of the X ray incided on sample 114.In certain embodiments, sample stage 110 can also rotate, to adjust the orientation of sample 114 relative to x-ray source 120.

X-ray detector 126 is for collecting the X ray reflected through sample 114.By analyzing the X-ray diffraction pattern detected, the related crystalline structural information of sample 114 can be obtained.

XRD device 100 can also comprise power supply 130, and its one end is connected to the upper surface of sample 114 by wire 132, and the other end is connected to first electrode 112 at the lower surface place being positioned at sample 114 by wire 134.In certain embodiments, wire 132 can be welded direct on the upper surface of sample 114.In further embodiments, the end of wire 132 can be welded with current-carrying plate such as copper coin, and this current-carrying plate can be adhered on the upper surface of sample 114 by such as conductive paste.This current-carrying plate answers area less, thus the wide area surface that can not cover sample 114 is to affect x-ray bombardment on sample 114.Wire 134 is connected to the first electrode 112 by the through hole on sample stage 110.In further embodiments, wire 134 also can be connected to the first electrode 112 from the side.In certain embodiments, sample stage 110 can rotate.Now, wire 132 and 134 can be fixed to the side of sample stage 110, in order to avoid affect the connection between wire and sample or electrode because of rotation.

As mentioned above, power supply 130 is executed alive to sample 114 while, X-ray diffraction measurement can be carried out, studies the impact of electric field on the crystal structure of sample 114.

In the embodiment shown in fig. 1, sample stage 110 and on the first electrode 112 and sample 114, x-ray source 120, beam adjuster 124 and X-ray detector 126 can be arranged in housing 102.When housing 102 is closed, can carry out vacuumizing or being filled with helium.Therefore, XRD device 100 can also include and bleed and charger.In the embodiment shown in fig. 1, power supply 130 can be arranged on outside housing 102.In further embodiments, power supply 130 also can be arranged in housing 102.
