Abstract :
A bunch length monitor for very short charge bunches based on microwave spectroscopy has been conceptually studied. It consists of a coaxial cavity coupled to the beam pipe through four symmetrical apertures. This signal excited by the bunch can be collected by a small antenna connected to a coaxial line transporting the signal to the measurement device. By frequency domain analysis of the measured signal it is possible to obtain the bunch length. The analytical frequency response relating the primary field radiated by the bunch in the beam pipe and the measurable electromagnetic field has been determined
