Title: Spectrometer drift
Post by: Joe Boesenberg on February 25, 2025, 01:18:46 PM
I want to see if my TAP spectrometer positions are drifting over a full day. I suspect they may be drifting over a few hours. How can I check spectrometer drift?

Here are some links on spectrometer reproducibility:

The following link discusses using the Remote Automation Excel scripts to perform extensive tests on your instrument. You can modify these scripts with any sort of delays you want:

There's also the Drift utility once you have a lot of data to sift through:

If you don;t need to test the reproducibility of the spectrometer movement, one can simply run the StartWin application, peak the 5 spectrometers on some elements, and then just run Startwin to acquire counts in re-cycle mode from the Modes menu.

Then you select the data lines and from the Output menu, click this menu:

Then select the columns you want to plot...

You can also set the "cycle time" between counting cycles from the Count Times button:
