Linac and THz radiation: Coherent Transition radiation mechanism

School
PARTICLES AND ACCELERATORS

Abstract:

A successful new application of intense THz radiation is the control of materials properties by high THz fields: insulatormetal transitions, orbital order, superconductivity, or spin waves can be controlled by the transient electric or magnetic field. Most of these experiments have up to now been performed with laser-driven sources which yield THz pulse peak fields in the 100 kV/cm regime routinely with the provided repetition rate of 1 kHz. However, the detected ultra-fast changes of materials properties are tiny and require even higher THz pulse energies at elevated repetition rates. In addition, important THz-driv ...
