Description
Longitudinal profile monitoring is crucial for assessing beamstrahlung effects in the FCC-ee, as well as for energy calibration—both fundamental from the physics point of view. From an operational perspective, bunch-by-bunch longitudinal profiles will be needed during machine commissioning and to assess the quality of bunches freshly injected from the booster. To overcome the limitations associated with the synchrotron light extraction, new techniques of longitudinal beam monitoring are being investigated, including electro-optical spectral decoding (EOSD) and the measurement of Cherenkov diffraction radiation (ChDR). This presentation will discuss the principles of these techniques and describe ongoing studies on their applicability to FCC-ee diagnostics.
