TI - An Ultrafast Linear Array Detector for Single-Shot Electro-Optical Bunch Profile Measurements
J2 - Proc. of IBIC2014
AB - A new spectrometer system has been developed at ANKA for near-field single-shot Electro-Optical (EO) bunch profile measurements with a frame rate of 5 Mfps. The frame rate of commercial line detectors is limited to several tens of kHz, unsuitable for measuring fast dynamic changes of the bunch conditions. The new system aims to realize continuous data acquisition and over long observation periods without dead time. InGaAs or Si linear array pixel sensors are used to detect the near IR and visible spectrum radiation. The detector signals are fed via wire-bonding connections to the GOTTHARD ASIC, a charge-sensitive amplifier with analog outputs. The front-end board is also equipped with an array of fast ADCs. The digital samples are then acquired by an FPGA-based readout card and transmitted to an external DAQ system via a high-speed PCI-Express data link. The DAQ system uses high-end Graphics Processors Units (GPUs) to perform a real-time analysis of the beam conditions. In this paper we present the concept, the first prototype and the low-noise layout techniques used for fast linear detectors.
