N2 - We have been studying a coherent Cherenkov radiation by using tilted electron bunches. Bunch tilting can enhance the radiation power about 10 times due to the wavefront matching of radiations. Recently, we investigated that this technique can produce high peak power THz pulses with sufficient pulse energy. The resulting pulse energy was more than 30 nJ/pulse and peak power was about 10 kW. Introducing the oscillator cavity with two concave mirrors can achieve lasing using tilted electron bunches. In the calculation we present, 1 μJ/micro-pulse and 100 μJ/macro-pulse broadband THz pulses are expected to achieve, which is powerful THz source compared with the existing THz FELs. In this conference, we will report the experimental results of coherent Cherenkov radiation, calculated results towards lasing and future prospective.
