Title:
X-RAY EMITTER, LIQUID-METAL ANODE FOR AN X-RAY SOURCE AND METHOD FOR OPERATING A MAGNETOHYDRODYNAMIC PUMP FOR THE SAME
Document Type and Number:
WIPO Patent Application WO2005091326
Kind Code:
A3
Abstract:
The invention relates to a method for operating a magnetohydrodynamic pump (5) for a liquid-metal anode (1) of an X-ray source. According to the invention, said pump can be operated in at least two modes, the first mode being a fusion mode, in which the liquid metal (2) is fused in a conduit (3) of the liquid-metal anode (1) and the second mode being an operation mode, in which the liquid metal (2) is pumped through the conduit (3) and X-ray radiation is generated. The invention also relates to a liquid-metal anode (1) for an X-ray source comprising: a liquid metal (2) that is contained in a conduit (3), an anode module (15) being inserted into the conduit (3) in the focusing region (4); a pump (5) for circulating the liquid metal (2) in the conduit (3); and a cooling system (6) for the liquid metal (2). According to the invention, a liquid-metal anode (1) of this type comprises a magnetohydrodynamic pump (5) that is configured as above.
