Acquiring an AES Three-Point Depth Profile
If you have not acquired a three-point depth profile before, it is recommended
you click here for more detailed information on how three point depth profiles work, as well
as information on choosing the appropriate analyzer parameters for each
element.
- Make sure that AES is selected as the acquisition technique.
- Set the AES elastic peak if you have changed or moved the sample. Click here to see the procedure for acquiring an elastic peak.
- If you are using an analog multiplier supply such as the model 20-075, you must re-set the multiplier voltage before acquiring a depth profile. Click here to see the procedure When you have re-set the multiplier voltage, make sure
the AugerScan document for the depth profile is the active window, display the
Depth Profile Settings dialog box, then skip to step 6.
(If you are using a digital multiplier supply such as the model 32-100, we
recommend that you re-check the multiplier plateau voltage on a monthly basis
because as a multiplier ages, it requires a higher voltage to produce the same
amount of signal. Click here to view the procedure for acquiring the multiplier gain curve to determine
the multiplier plateau voltage.)
- Select the New Three-Point Depth Profile command from the Acquisition menu.
- In the Select Element dialog box, click on the elements for which you want to
acquire the depth profile. (If the element you want isn’t in the list, click on the New Element button to add the element to the
list.) Click on OK to close the Select Element dialog box.
- Define the acquisition settings in the Three-Point Depth Profile Settings
dialog box. Note: If you didn’t include all the elements you wanted to when you defined the elements in the
depth profile, click on the Add button in this dialog box. Use the What’s This Help to determine the appropriate values for each field.
- Click on the Acquire command button to begin acquiring the depth profile.
- Once your depth profile is displayed, you can expand the X-axis scale if necessary.
