MIRCOFOCUS X-RAY TUBE FOR A HIGH-RESOLUTION X-RAY APPARATUS

摘要

An apparatus is provided for a micro focus X-ray tube for a high-resolution X-ray comprising a housing, an electron beam source for generating an electron beam and a focusing lens for focusing the electron beam on a target. The X-ray tube comprises a substantially rotationally symmetrical, ring-shaped cooling chamber configured to circulate a liquid cooling medium.
