ABSTRACT:
An electron beam heating system includes a cathode, an anode, a CNT string and a chamber. The CNT string includes an end portion and an emission portion, and the end portion is contacted with and electrically connected to the cathode. The cathode, the anode and CNT string are arranged in the chamber. The CNT string is composed of a plurality of CNT bundles packed closely, each of the CNT bundles comprises a plurality of CNTs, the CNTs are substantially parallel to each other and are joined by van der Waals attractive force. Electron beams emitted from the emission portion bombard and heat a predetermined point on the anode. The heating efficiency of the electron beam heating system is high.
