Description
For future experiments at the European XFEL an ultra-low charge mode is foreseen. The tight requirements on the facility wide synchronization system are even more crucial in these experiments, while the conditions for the electro-optical bunch arrival time monitors become worse.
In this talk the first step towards a sufficient improvement of the arrival-time measurement is presented. Following from the radial dependency of the sensed electric field, an aperture reduction from 40.5 mm to 10 mm gives a significant increase. In simulations a factor of 3.9 is found with a well-shaped bipolar signal and acceptable ringing. This first step contributes nearly 60 % of the overall goal and will be accompanied by further improvements.
