Coherent sychrotron radiation detector for a non-invasive subpicosecond bunch length monitor

PDF Version Also Available for Download.

Description

This CSR detector was developed to monitor nondestructively the length of a subpicosecond bunch with high sensitivity. The monitor uses a state of the art GaAs Schottky whisker diode which is operated at room temperature at a wavelength of a few hundred microns. The detector is capable of detecting radiation power as low as 10 nW, depending on wavelength. This paper describes design specifications, parameter ranges, and monitor features and also reports its performance and comparison between measurement and calculation. The measurement results are cross-compared with an independent bunch length measurement using phase modulation. It was found that the output ... continued below

The detector is capable of detecting radiation power as low as 10 nW, depending on wavelength. This paper describes design specifications, parameter ranges, and monitor features and also reports its performance and comparison between measurement and calculation. The measurement results are cross-compared with an independent bunch length measurement using phase modulation. It was found that the output power varies with bunch length and that detectors at shorter wavelengths are preferred.
