EFFUSION CELL SERVICES

VESCO-NM services all other vendors’ effusion cells. In most repair cases we replace all parts of the effusion cells except the mounting flange. Our effusion cells heaters and thermocouples are well-known as the most reliable and robust heaters for all MBE harsh and low-vacuum (1E-2 torr) environments, including oxide and nitrides systems. Our seamless tantalum tubes are much stronger and never erode or crack due to gallium or aluminum penetration, the common failures appearance of the thin-wall outer tube cells. Our modified cells have longer life time and are easy to operate and maintained. We have repaired and modified over 500 effusion cells of other vendors with no return. Our lead time and after-service are satisfactory and our prices are very competitive.
