Acquiring a SIMS Survey
To find out more about surveys, click here .
Note: For UTI SIMS systems, analyzer, gating, and polarity functions must be
controlled manually, so you need to adjust your procedure for acquiring data
accordingly. Note, however, that AugerScan will still record and display the
values placed in these fields so you can use them for bookkeeping.

- Set the AES elastic peak if you have changed or moved the sample. Click here to see the procedure for acquiring an elastic peak.
- Make sure that SIMS is selected as the acquisition technique.
- If you are using an analog multiplier supply such as the model 20-075, you must set the multiplier voltage manually before acquiring a survey. This voltage
is determined by increasing the voltage on the 20-075 SIMS multiplier until no
further increase in counts is noted.
- Select the New Survey command from the Acquire menu or click on the New Survey
button in the main toolbar. The Survey Settings dialog box is displayed.
- Define the acquisition settings in the Survey Settings 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 survey.
Once you’ve acquired the survey, you can continue working with the data, thereby “transforming” it. This includes smoothing, differentiating, tracking and marking,
annotating, and calculating atomic concentrations. Click here for more information about raw and transformed data. We recommend that you
save your data before you transform it in any way because some operations result
in permanent changes to the data that cannot be undone.
