One of the optimization goals of a particle accelerator is to reach the\nhighest possible beam peak current. For that to happen the electron bunch\npropagating through the accelerator should be kept relatively short along the\ndirection of its travel. In order to obtain a better understanding of the beam\ncomposition it is crucial to evaluate the electric charge distribution along\nthe micrometer-scale packets. The task of the Electro-Optic Detector (EOD) is\nto imprint the beam charge profile on the spectrum of light of a laser pulse.\nThe actual measurement of charge distribution is then extracted with a\nspectrometer based on a diffraction grating.\n The article focuses on developed data acquisition and processing system\ncalled the High-speed Optical Line Detector (HOLD). It is a 1D image\nacquisition system which solves several challenges related to capturing,\nbuffering, processing and transmitting large data streams with use of the FPGA\ndevice. It implements a latency-optimized custom architecture based on the AXI\ninterfaces. The HOLD device is realized as an FPGA Mezzanine Card (FMC) carrier\nwith single High Pin-Count connector hosting the KIT KALYPSO detector.\n The solution presented in the paper is probably one of the world fastest line\ncameras. Thanks to its custom architecture it is capable of capturing at least\n10 times more frames per second than fastest comparable commercially available\ndevices.\n
