Abstract

1.1 Applications

Type YX***0 X-ray crystal orientation unit is designed on the principle of x-ray diffraction. It is a indispensable instrument for precise orientating of various natural and artificial single crystals (such as piezo-crystal optical crystal laser crystal, and semiconductor crystal ECT)

it Is can used in above-mentioned of different crystal orientation cut , it is make crystal device indispensable instrument to process set with cutting machine.

1.2  Features

A).Easy for Operation.

B).Digital display for angles.

C).Display may be reset at any angle,  for user setting crystal angle.

D).Special integrater is used for peak enlargement to increase accuracy.

E).Modularized circuit makes maintenance  easier.

F).Reasonable structure design, to protect the user from x-ray injury.

G).Sample with different size can be measured with various attachments.

(It depends on different needs)

3.The  principle

High voltage generator  supply  X-ray tube with high voltage, product x-ray, shoot on the sample,  according to nλ=2dsinθ,product diffraction, and the digital counter absorb the x-ray and display through the uA meter.

4. Component and Features

4.1.YX***0 x-ray orientation unit is consisted of mechanical part, which made up with the table, tube housing , goniometer and various accessories; and electrical part ,which made up with voltage stabilizer and controller , high voltage transformer, magnifying, digital counter, air pump , cooling fan , x-ray tube.

4.2. The tube housing of orientation unit is horizontal and the cover is on the top , Easy to  replace the x-ray tube.

4.3. Counter tube and samples share one scale, in the face of operator, easy to read.

4.4. Counter tube relative to the sample distance is adjustable at his arm, in order to meet and measure the need of the sample of different size.

4.5. Air pump  have long performance life , it is convenient to maintain.

4.6. The switch of power,  voltage of x-tube and the current knob are  in the front of the tube housing.

4.7 Safety  defence  cover  to avoid  x-rays injury to the user.

5.  Installation and adjusting

5.1. This unit is also need the following conditions:

(1) Place where be well-ventilated, and less dust.

(2) Place where flat and no shake.

5.2. Installation

This unit should be place in the room after open the packing box, the first item, you should check the parts according the packing list. if there are some problem, you should contact with the factory immediately .

(1) The preparation  before installation

Should have the necessary tools for moving  and  install  this unit.

Should clean the unit after open the packing box  . clear the x-ray tube and the voltage cable .the body of the unit should be firmed.

(2) The installation of the x-ray tube and the voltage cable

Keep the x-ray tube and the voltage cable clean ,first loose the screws over the cover , then move the cover ,and loose the screws on the nipM3,and make the x-ray tube and high voltage cable become a whole. put the x-ray tube in tube housing .

Caution: Dont contact with the Be window of X-ray tube during the installation .dont link the high voltage cable temporarily with high voltage transformer. 

(1)   Counter installation

First check it carefully, install this unit on the arm at  goniometer, the distance is the shorten the best between this unit and center of the sample , connect the cable plug with the outlet.

(2)   Cable connect

a).The first you must discharge the connector on the high voltage transformer with earth!!

and then connect the high voltage cable with the high voltage transformer, with screw (M5)

b) Connect the power cable with D1, D2 (big hole)

c).This unit must has earth connection  . (smaller hole)

5.3. Testing.

On the basis of the good installation . Switch on the main power , the indicator lamp will be light (red).the following should work well.

(1) X-ray tubes filament is light, adjust the mA  knob, at the same time, the brightness of filament  should change. 

(2) The cooling fan  should work and make voice.

(3) Switch on  the air pump, the sample plan can attract the standard sample.

(4) Push ON button of the high-voltage, the high-voltage indicator lamp is light (red), Open the shutter of X-ray , there is X-ray penetrates. In order to check whether there is X ray that penetrates, you can adopt the fluorescence board or through the partly display of the counter and uA meter

Under the condition of the X-ray penetrates and normal work of partly display,

Calibration goniometer  as follows,

a)     Put standard quartz  (***1 ) at the sample plan,

b)    Unclamp the fastening hand knob of the detector, move the detector to reach *6°*0'(Examine the angle scale indicator on the angle appearance through observing), then lock the hand knob.

c)     Rotate the hand wheel and transfer the sample to *3°*0, regulate every knob of the register in the best position,  Switch on the high-voltage and open X-ray shutter, slightly rotate the hand wheel until intensity is highest on uA meter indicator, at this time you can preset the digital switch to the *3.*0.0,and then press the reset key, or you can set the digital switch to the *0.*0.0, if you like then press the reset key.
