New method for RF field amplitude and phase calibration in flash accelerator

The paper presents new method for amplitude and phase calibration of the RF field in FLASH accelerator. The concept is based for detection and measurement of transients induced by single bunch. These transients are very small and it is not possible to detect them without special hardware. The paper presents the measurement system developed for a single bunch induced transient detection. The results of measurement obtained with this system are presented proving its correct operation
