Impulse software

Impulse software gives researchers complete control over stimuli applied within DENSsolutions in situ TEM holders. With Impulse, you can easily design your in situ experiment from your desk and store experiments so you can reliably reproduce results. While on the microscope, Impulse will automatically control the sample environment while you focus on the sample.

For Teams and User Facilities

Impulse is specifically designed with research groups and user facilities in mind. Are you leading a research group with long term projects involving multiple researchers? Impulse makes it easy to design, save, and share experiment workflows so that the project can seamlessly continue and evolve.

Impulse key features

Smart automation

Easily design your experiment with a drag-and-drop profile builder. During the experiment, you can focus on other things while smart automation keeps track of the measurements and ensures the programmed conditions are met. Easily reproduce your stimuli and test multiple iterations, accelerating your ability to discover which parameters are critical to your functional material.

Flexible dashboard

Customize and arrange your dashboard so that you never miss a thing. There is no limit to the amount of data you can display on the dashboard, allowing you to see correlations and make real-time decisions during in situ experiments.

Data integration

Synchronize your stimuli data with other data from your experiment and generate annotated images and graphical data in seconds. Currently compatible with TVIPS and Gatan software.

Experimental freedom

Conduct unique experiments by leveraging your own Python scripts. Use custom scripting to communicate with different equipment such as the microscope, cameras, detectors, and the DENSsolutions in situ system. Select from premade scrips or generate your own to unleash your full creativity.
