The Evactron E50 De-Contaminators are compact, high performance, yet simplified plasma cleaners specifically developed for ion and electron beam instruments, such as SEMs, TEMs and FIBs.
The E50 De-Contaminator allows high power cleaning for outstanding imaging and resolution and provides enhanced probe and detector sensitivity that is normally impacted by contamination.
The Evactron E50 Plasma Radical Source (PRS) features a small-sized design, making it a universal solution for sample preparation chambers, either SEM or FIB chambers, or load locks.
The Evactron E50 De-Contaminator offers quick, robust and effective cleaning over a wide range of pressures, thereby enabling artifact-free, high quality images, as well as enhanced sample analysis efficiency.

Evactron E50
The Evactron E50 plasma De-Contaminator has been combined with wireless tablet programming and has been designed to remove hydrocarbon contamination from high vacuum chambers, such as SEMs and FIBs.
The Evactron E50 Plasma De-Contaminator’s compact design houses majority of the models of load-locks and SEM and FIB chambers. The Evactron E50 makes use of air plasma and UV afterglow to rapidly decrease hydrocarbon contamination.

Evactron E50 E-TC
The Evactron E50 E-TC Plasma De-Contaminator has been particularly designed for facilities that need a wired touchpad interface for programming purposes.
The touchpad, which measures 134 × 112 × 69 mm, is linked to the controller via an RS-232 cable. The simplified PRS has a compact footprint and makes use of air plasma and UV afterglow to remove hydrocarbon contamination, and hence provides immediate results.

Plasma cleaning of the sample prior to TKD experiments affords many advantages. The improvement in pattern quality and enhanced measurement efficiency is needed for extended experiments, which can include fast and multiple scans at the same sample position (e.g., for repeated in-situ heating or straining experiments). The advantage of plasma cleaning is recommended for all high resolution TKD experiments. Plasma cleaning the sample inside the microscope chamber is recommended since the chamber, detectors and the holder are cleaned simultaneously.
