Absolute scale power measurements of frequency-locked coherent transition radiation
We report the absolute power measurement of frequency-locked terahertz coherent transition radiation (CTR) from a train of electron bunches produced by a 17.14 GHz accelerator. Frequency measurements were obtained by two independent techniques: a wave meter with a video diode detector, and a double heterodyne system. Good agreement was seen between these two techniques. The emitted radiation wa...
متن کاملA Radiometer for Precision Coherent Radiation Measurements
A radiometer has been designed for precision colierent radiation measurements and tested for long-term repeatability at wavelengths of 488 and 633 nm. The radiometer consists of a pn silicon photodiode maintained in a nitrogen atmosphere with a quartz window designed to eliminate interference problems. Ratio measurements between the radiometer and an absolute type detector were made over a peri...
متن کاملProposed Coherent Diffraction Radiation Measurements of Bunch Length at Asta
The feasibility of using the autocorrelation of coherent diffraction radiation (CDR) as a non-intercepting diagnostics technique for bunch length and indirectly rf phase measurements is evaluated and proposed for the Advanced Superconducting Test Accelerator (ASTA) facility under construction at Fermilab. Previous experiments on an rf thermionic cathode gun beam at 50 MeV provide a proof-of-pri...
متن کاملFirst Measurements of the Facet Coherent Terahertz Radiation Source
The Facility for Accelerator science and Experimental Tests (FACET) at SLAC provides a high charge, high peak current, sub-picosecond bunched electron beam that is ideal for 0.1 to 2 THz radiation generation via coherent transition radiation. This paper presents preliminary characterization of the terahertz pulses generated by the FACET electron beam. The measured THz frequency content spans fr...
متن کاملExperimental Observation of Ifel Micro-bunching Using Coherent Transition Radiation
Electron beam bunching in the optical wavelength was observed experimentally for the first time at the Brookhaven Accelerator Test Facility(ATF) using the Inverse Free Electron(IFEL) accelerator. The micro-bunched electron beam has been studied by measuring the coherent transition radiation (CTR). We have experimentally observed a quadratic dependency of the CTR signal with the charge of the el...
