Outline of Final Research Achievements

The operation of the DC-to-AC radiation converter (DARC) in the sub-THz region is confirmed. A relativistic ionization front which is created by a loosely focused of Ti:sapphire laser pulse propagating through a capacitor array of period d = 0.2 cm with a gas pressure between 1 and 200 Pa. The maximum frequency of the generated emission is determined to be in the range of 0.1 to 0.3 THz by using several diodes.; The maximum frequency range observed is up to Y band (0.22-0.33THz), which is the highest frequency reported using the DARC with gas (to our knowledge). Theoretically, higher frequency can also be obtained with higher electron density. The maximum signal voltage as a function of the applied voltage. The maximum signal voltages increase with the increasing applied voltage.
