E50 Plasma Cleaning Systems

The Evactron® E50 series of plasma de-contaminators provides high performance and high power plasma cleaning in a compact and easy to use form factor. Suitable for use with SEM, TEM, and FIB instruments, the E50 plasma cleaners provide high power cleaning to ensure maximum performance. The E50 technology uses an external hollow cathode RF (XHCRF) plasma radical source for high power and efficient operation.

The E50 plasma cleaners are very easy to set up and operate, and feature a touch screen tablet interface, with a simple “one button” cleaning control. Advanced parameters such as power, cleaning time, and cycle counts can also be adjusted, and saved as user-programmable recipes. The compact design of the E50 plasma sources makes them ideal for attaching to crowded SEM and FIB chambers.

Sample Cleaning

Contamination from hydrocarbon build-up inside instruments and on samples can compromise high resolution image quality and sensor sensitivity. The plasma de-contamination technology used by Evactron’s E50 plasma cleaners provides a fast, effective, and gentle method of removing contamination. This ensures that high-quality, artefact-free imaging and efficient analytical measurement is possible. The E50 plasma-decontaminators do not damage samples, and cause no sputter etch.
