AXON DOSE: PRECISION DOSE MANAGEMENT FOR RELIABLE RESULTS

The electron beam can profoundly influence sample behavior, sometimes producing desired effects and sometimes introducing unwanted changes. Accurately understanding dose exposure across the sample at every stage of the experiment is essential for ensuring reliable results and reproducibility. AXON Dose is the first and only software of its kind that fully automates the calculation and recording of electron dose throughout the entire TEM workflow. By automating a traditionally labor-intensive and error-prone process, it establishes a new standard of reproducibility from one experiment to the next, and across multiple labs. 

INCREASE REPRODUCIBILITY

A unique external Faraday cup and power supply deliver reproducible, quantifiable measurements, ensuring consistent results across any TEM

SHARE EASIER

All dose measurements are automatically aligned and indexed into the metadata, ensuring they’re readily accessible to anyone reviewing the data in AXON Studio

INTERPRET FASTER

Intuitive visualization tools aid in understanding dose effects on sample behavior

EXAMPLES USING THE AXON DOSE MODULE

VISUALIZE DOSE

Colorful dose overlays introduce an entirely new way to visualize dose exposure. Electron dose is measured on a pixel-by-pixel basis and tracked throughout the entire experiment for both TEM and STEM modes, ensuring a detailed, continuous record. Colorized maps highlight actual exposure levels and indicate when approaching critical thresholds. 

 

In this video: The colorized dose overlay dynamically updates while going through the timeline, reflecting the increase in cumulative dose exposure over time. The colors shift toward red or pink as user-defined thresholds are approached, providing a clear visual warning.

IDENTIFY DOSE LIMITS

Tools like spot fading quickly pinpoint when and where the electron beam first contacts your sample, helping you understand the beam’s influence based on dose rate or cumulative dose. Once dose thresholds are identified, the software allows you to set warning indicators. Colorful dose overlays then provide clear alerts for approaching dose levels.

 

In this video: The live FFT is used to detect beam damage in a ZSM-5 zeolite sample from Zeolyst, which becomes amorphous when exposed to prolonged e-beam. Once the dose level where the ZSM-5 particle turns completely amorphous is identified, the dose threshold can be set accordingly. The colored maps will then adjust to help monitor and manage dose limits in future experiments.

A BIRDS-EYE VIEW

The dose navigation pane shows a low-magnification view of the stage and the same colorized dose maps show where the beam has been previously. Move to pristine areas with a simple double-click in the navigation pane to quickly begin a new experiment

 

In this video: the dose navigation pane (right) indicates the location of the most recent experiment with the same dose map overlay as shown on the image (left). A double click in the navigation pane moves the field of view to a pristine area while the previous location is still identifiable.
