backward mode
3.Move the storehouse calls change the storehouse again, it is to point to will existing cash forward or trade migratorily backward, particular mode of operation is will existing while cash makes the same score a storehouse, be in the near future or long-dated and new build the position with same way, equal amount.
6.Under the condition of given pump laser energy, using a lens with short focal length to focus the Cr∶LiSAF electrooptical ?Q- switched ? laser pulses into CS 2 SBS-cell, the backward SBS scattering of broad-band and multi-transverse-mode Cr∶LiSAF laser pulses is realized, and the effective pulse width′s compression is observed.
8.Based on the beam-wave mode-coupling theory, a principle of gyrotron device utilizing a hybrid interaction scheme of Backward-Wave Oscillator, Klystron Ballistic-Bunching and Traveling-Wave Tube (Gyro-BWO-KBB-TWT) is presented in this paper.
10.The BWO(Backward-Wave Oscillator) slow-wave structure was optimized by the KARAT code,and the experiment was performed at the RADAD303 accelerator flat under the condition of the electron beam with the voltage of 177kV,the current of 785A,and magnetic field of 1.TT. TE_(11) mode millimeter wave was generated,whose peak powe is 18MW,frequency 39.8GHz and pulse duration 3ns.
