FLAP Collaboration: Tasks and Perspectives. Study of Fundamentals and New Applications of Controllable Generation of Electromagnetic Radiation by Relativistic Electrons Using Functional Materials

Abstract

We present the scope of research of a new collaboration FLAP (Fundamental & applied Linear Accelerator Physics collaboration) devoted to the study of the basics of electromagnetic interactions and new applications of controllable generation of electromagnetic radiation by relativistic electrons using functional materials.

Martin-Puplett interferometer for studying THz and subTHz radiation

“…The interferometer will become the starting point for the development of a diagnostic system at stations for generating terahertz radiation. Due to the lack of availability of a calibration monochromatic source of terahertz radiation, calibration and measurement of the main characteristics of the device are planned to be performed using bunched relativistic electron beams at the Ro ntgen-1 facility [26] (electron energy 7 MeV) and LINAC-200 [27] (electron energy from 26 to 200 MeV). The possibility of integrating an optical modulator (chopper) into the design of the interferometer allows it to be used also with continuous beams of charged particles, including low energies [6,28].…”
