Design of THz setup in the restricted geometry available in high-field magnets

The high power THz radiation and high magnetic field is very promising combination from scientific perspective, however the design of an experimental setup inside high-field Bitter magnet is challenging task because of the space limitation. Therefore, the THz beam profile after broadband waveguides plays a key role. We experimentally study the behavior of THz-field profiles after oversized circular waveguide over broad range of frequencies. Results show that the THz beam divergence allows the design of a pump-probe experiment in high fields generated by Bitter magnets.
