Title:
CERAMIC TRANSFER TUBE AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/148034
Kind Code:
A1
Abstract:
The present application relates to the technical field of trace detection, and in particular relates to a ceramic transfer tube and a fabrication method therefor. The ceramic transfer tube comprises: a transfer chamber; an ionization chamber, which is disposed at one end of the transfer chamber; a Faraday cup assembly, which is disposed at the other end of the transfer chamber; an ion gate assembly, which is disposed between the ionization chamber and the transfer chamber; and a suppressor grid, which is disposed between the transfer chamber and the Faraday cup assembly, wherein the transfer chamber comprises a plurality of annular insulating ceramic sheets and a plurality of annular metal electrode sheets, the annular insulating ceramic sheets and the annular metal electrode sheets are alternately arranged in sequence, and adjacent annular insulating ceramic sheets and annular metal electrode sheets are sealed and welded. Compared to the prior art, the annular insulating ceramic sheets and the annular metal electrode sheets in the transfer chamber are alternately arranged in sequence, and the adjacent annular insulating ceramic sheets and annular metal electrode sheets are sealed and welded, which is convenient for installation and allows for low fabrication costs, good sealing performance, a reliable and firm connection, high mechanical strength, and strong shock resistance, which thus improves system stability.
