Description

To understand the underlying complex beam dynamics
in electron storage rings often large numbers of single-shot
measurements must be acquired continuously over a long
period of time with extremely high temporal resolution. Pho-
tonic time-stretch is a measurement method that is able to
overcome speed limitations of conventional digitizers and en-
able continuous ultra-fast single-shot terahertz spectroscopy
with rates of trillions of consecutive frames. In this con-
tribution, a novel ultra-fast data sampling system based on
photonic time-stretch is presented and the performance is
discussed. THERESA (TeraHErtz REadout SAmpling) is a
data acquisition system based on the recent ZYNQ-RFSoC
family. THERESA has been developed with an analog band-
width of up to 20 GHz and a sampling rate of up to 90 GS/s.
When combined with the photonic time-stretch setup, the
system will be able to sample a THz signal with an unprece-
dented frame rate of 8 Tf/s. Continuous acquisition for
long observation times will open up new possibilities in the
detection of rare events in accelerator physics.
