N2 - In this paper, the cold-fluid model theory is developed to investigate the effective method to decrease the Diocotron instabilities for the transport of high density sheet electron beam with the increase of magnitude of uniform magnetic field and the filling factor of the beam in transport tunnel, and the corresponding experiment is carried out to verify the conclusion obtained. Then, the several kinds of sheet beam tube for X-band sheet beam klystron (XSBK) and W-band sheet beam klystron (WSBK) are developed, manufactured and tested respectively. For the XSBK tube with PCM system, with the sheet beam cross section of 50×4mm 2, beam voltage of 110kV and beam current of 42A, the experimental transmission rate is more than 92% with the drift length of 300mm. For the WSBK tube with Wiggler system, with the beam cross section of 10×0.5mm 2, beam voltage of 55-65 kV and beam current of 2.28-2.86A, the transmission rate is more than 95% with the drift length of 50mm. For the WSBK tube with uniform magnetic system, with the beam voltage of 20-82 kV and beam current of 0.50-4.27A, the transmission rate is above 98% with the drift length of 100mm.
