Telecommunication Concepts for Compact, Electro-Optical and Frequency Tunable Sensors for Accelerator Diagnostics

Terahertz diagnostics for investigating the properties of electron and photon beams, especially the investigation of electron bunch instabilities, accompanied by terahertz photon bursts is increasingly employed to monitor and investigate electron bunch dynamics. Recent advances in information and communications technology promise compact sensors based on telecom and thus industry standards. We present potential applications of such technology concepts for accelerators, including a miniature probe for electrooptical sampling, which could be employed for electron bunch electrical near-field studies, and laser sources with widely tunable pulse repetition rates adaptable for pulsed diagnostics.
