            Abstract : 
A strong-coupling five-gap barbell output cavity is investigated combined with the design of W-band sheet beam extended interaction klystron (SBEIK), which may have many advantages of resonant mode separation, gap fields coupling and RF energy exporting with high efficiency. Then the output cavity is used to construct a high gain W-band SBEIK with eight multiple-gap cavities. With the sheet beam voltage of 75kV, and the current of 4A, the output power can attain to 32kW with the gain high than 50dB. The result agrees very well with the one-dimensional calculation program.
