Evactron U50 UHV Vacuum Chamber Cleaning System

Fast, effective and powerful cleaning over a wide range of pressures

The Evactron U50 De-Contaminator is a compact, high performance yet simplified plasma cleaner for instruments and chambers designed to operate at UHV conditions. The U50 delivers high power cleaning for removal of hydrocarbon contamination on chamber and sample surfaces.

The compact design of the Evactron U50 Plasma Radical Source (PRS) makes it a versatile solution for either instrument chambers, load locks, or sample prep chambers. The Evactron U50 offers fast, effective, and powerful cleaning over a wide range of pressures, enabling hydrocarbon-free RGA spectra and fast pump down time to UHV.

RF Power - 75W peak, 50W continuous power output

Bakeable design - Withstands backout to 150°C; TMP-compatible with no advance venting

Dual-action cleaning - Combines plasma and UV afterglow to remove hydrocarbon contamination

UHV compatibility - Conflat 2.75 flange and a leak rate below 10-11 Torr make it UHV-ready

Energy Efficient - Hollow cathode, capacitive coupled plasma (CCP) technology

Programmable control - Power, cleaning time, cycle count and recipes are all user-programmable

Fast cleaning - > 100x faster than earlier Evactron models, with simple push-button operation

Alternative gases - run a range of process gases to tailor the cleaning chemistry to your application

Wide pressure range - Operation from 0.3 Pa to 80 Pa (2 mTorr to 600 mTorr)

External interlock - Optional external interlock connection for safety
