Description
Characterizing bunches non-destructively is extremely useful in a variety of accelerator use cases. In single-event effects testing with pulsed electrons, the bunch charge (~1-10 fC) needs to be measured precisely so that the microelectronic device response can be well correlated with the delivered dose. Cavity-based beam monitors, based on wake field excitation from the beam, offer a highly sensitive single-shot measurement for both charge and time of arrival. Recent experiments at UCLA PEGASUS have shown sub-fC sensitivity, with ongoing work to understand the theoretical and practical limits for measuring the bunch charge. The wake field signal also gives access to the time of arrival information for the bunch, paramount for probing temporal dynamics in schemes like ultrafast electron diffraction. Efforts at UCLA are ongoing to understand the sensitivity limits of the arrival time monitor, making using of THz streaking as a secondary independent diagnostic for the time of arrival of the beam.
