Abstract
- A high-speed YBa2Cu3O7-δ direct detection system was developed to monitor terahertz picosecond pulses in the time domain. High-TC superconducting thin-film YBa2Cu3O7-δ microbridges with critical temperatures of TC = 85 K were embedded into a planar log-spiral antenna to couple the broadband terahertz radiation (0.1 -2 THz) of several picosecond pulsed sources. The YBa2Cu3O7-δ detectors were installed in a liquid nitrogen cryostat equipped with 18 GHz effective bandwidth readout electronics. THz pulses generated at the electron storage rings ANKA and UVSOR-II have been resolved with a temporal resolution of 30 ps (full width at half maximum) limited by the readout electronics bandwidth. Beam dynamic effects of bursting coherent synchrotron radiation were successfully monitored.
