two differences from the klystron give it a lower cost and higher efficiency. first, the klystron uses "velocity modulation" to create bunching; its beam current is constant. it requires a drift tube several feet in length to allow the electrons to bunch. in contrast the iot uses "current modulation" like an ordinary triode; most of the bunching is done by the grid, so the tube can be much shorter, making it less expensive to build and mount, and less bulky. secondly, since the klystron has beam current throughout the rf cycle, it can only operate as an inefficient class-a amplifier, while the grid of the iot allows more versatile operating modes. the grid can be biased so the beam current can be cut off during part of the cycle, enabling it to operate in the more efficient class b or ab mode.
