Figure 7-9: Goebel mirror primary optics with 0.2 mm exit slit and knife edge.

5) Ensure that the following slits and filter are installed in the secondary optics (see Figure 7-10), in the

order shown.

a) 3 mm anti-scatter slit

b) Bragg-Brentano: Ni 0.5 absorber (x-ray kβ filter) 11

c) 2.5° vertical Soller slits (reduces lateral beam divergence)

d) 8 mm anti-scatter slit

6) Close the XRD2 cabinet doors, pushing both handles firmly into the locked position.12

11 A kβ filter is not required in the secondary optics when using the Goebel mirror because it filters out the kβ x-rays. The number

0.5 on the Ni absorber indicates that that the kβ:kα1 ratio is reduced to 0.5%. The unfiltered kα1:kα2:kβ ratio is 10:5:2.

12 If the handles are not pushed into the locked position, a door closure error may be triggered, in which case the x-ray generator

will switch off.

7.4.2 Automated Operation

7.4.2.1 Introduction

A job is a measurement recipe, which allows the operator to specify a sequence of temperature changes

and XRD scans, which can then be run unattended. It is particularly useful in conjunction with the ther-

mal/vacuum stage.

The first step in creating a measurement recipe is to create a parameter file using XRD Wizard (see Section

7.4.2.2). The temperatures at which XRD measurements are desired, temperature ramp rates, and the XRD

scan parameters are defined in the parameter file, which has the file extension .dql. A parameter file may

be created from scratch but, usually, it is simpler to copy an existing parameter file, save it with a different

name, and modify it as needed.

After creating the parameter file, create a job using XRD Commander (see Section 7.4.2.3).

7.4.2.2 Create or Modify a Parameter File

Create a new parameter file or modify an existing parameter file as follows. Usually, it is simpler to do the

latter.

1) Ensure that XRD Commander is closed.

2) Open XRD Wizard.

3) In the menu bar, select either:

a) File: Open and browse to the desired parameter file to be modified e.g., a copy of

C:\\DIFFDAT1\Reference\XRD_vs_T_Example.dql or

b) File: New.

The parameter file should open in the XRD Wizard window, as shown in Figure 7-13. Selection of a

category in the tree view on the left opens a pane on the right, which displays the parameters for that

category.

7.6 Data Analysis with EVA

Simple data analysis of .raw files may be performed using EVA software, including:

Background subtraction

kα2 peak removal

Offset removal

Addition or subtraction of scans

Merging of scans covering different angular ranges.

For information, refer to the EVA manual. Pattern matching is a feature of EVA which is unavailable be-

cause we have no powder diffraction file database.

The measurement file with the extension .raw is not affected by processing with EVA. Instead, files saved

by EVA have a proprietary Bruker format with file extension .EVA. EVA files may be converted to text files

by the following procedure.

1) In EVA, select File: Export to export the file to .raw format. Avoid overwriting the measurement file,

which has the same file extension.

2) Open File Exchange (see Figure 7-20).

3) In the Input file(s) section:

a) Type: Select Diffrac (AT/plus) Raw.V1.4.

b) Path: Browse to the .raw file to be converted.

4) In the Output file(s) section:

a) Type: Select Diffrac Exchange Format (UXD).

b) Name suffix: Type a suffix or leave blank, as desired.

c) Path: Browse to the desired destination folder for the text file.

5) Select other options, as desired.

6) Click Convert, to convert the .raw file to a text file with file extension .uxd.

7) When finished, click Exit.
