microCMA Software Update – New Features for Auger Multiplexes

This past year there have been a number of new features added to CMapp – the application software for the microCMA. Most of these provide you with improved (and safer) control of your microCMA hardware. For example, there’s is now a “Dynamic Mode” feature that assists in automatically conditioning the multiplier.

The most significant addition to the CMapp software is the Multiplex Survey Region View.

Earlier versions of CMapp – like its AugerScan cousin – displayed Multiplex data in two ways – either individual survey region windows, or a bar graph representing the peak-to-peak or atomic concentration (a.c.) data.

The most recent version of CMapp (0.4) has an additional view, which displays the survey region data in one graph of kinetic energy vs. counts or concentration. It’s now much easier to visualize all of the survey data in one window. Additionally, the graph updates in real-time while acquiring, much like a single survey.

This latest feature was actually added to CMapp in a recent previous version, but we’ve updated it to provide the option to order data legend and atomic concentration table by energy, alphabetically, by descending atomic concentration, or by the order the regions were added to the acquisition.

You can change the order of regions in the legend (and in the optional atomic concentration annotation) in the View menu – choose the Options command, Graph tab:

We’ll be soon be updating our YouTube channel with more microCMA tutorial videos to help you get the most out of your compact Auger analyzer and CMapp software.

New Feature: Use the 9103 Picoammeter to Automatically Read microCMA Target Current

The latest software releases of Actuel for the 9103 Picoammeter and CMapp for the microCMA now support the ability to automatically read target current when acquiring data.

To use this feature, you must (of course) have a 9103 Picoammeter running RBD’s Actuel software.

Run CMapp for the microCMA, select Hardware Properties from the System menu, and check the option “Use 9103 Picoammeter to read target current.” You only have to do this once.

Turn on the 9103 Picoammeter, run Actuel, and measure your target current as usual. Leave Actuel open. It doesn’t matter whether the 9103 is sampling, but keep in mind that your current settings (sample rate, etc.), will be used.

Now, whenever you take an acquisition (except for an alignment), the target current will be measured at the beginning of the acquisition and displayed with the other electron gun settings when the acquisition is complete.

If you don’t have a 9103, you can still manually enter a value for the target current in the acquisition dialog.
