Frank laboratory of Neutron Physics, Joint Institute for Nuclear Research, Dubna, Russia Software for a data acquisition system of modern one- and two-dimensional position-sensitive detectors with delay-line readout, which includes a software interface to a new electronic module DeLiDAQ-2D with a USB interface, is presented. The new system after successful tests on the stand and on several spectrometers of the IBR-2 reactor has been integrated into the software complex SONIX [1]. The DeLiDAQ-2D module [2] contains an 8-channel time-code converter (TDC-GPX) with a time resolution of 80 ps; field programmable gate array (FPGA) where the firmware stored and executed, performing logical operations, selection and filtering of events; 1 Gbyte histogram memory, which makes it possible to accumulate three-dimensional spectra X-Y-TOF of up to 512×512×1024 32-bit words; and high-speed interface with fiber-optic communication line. The real count rate (with consideration for data transfer and recording to a PC) is no less than 106 events/s. The DeLiDAQ-2D module is implemented in standard NIM. The DeLiDAQ-2D module can operate in two modes: histogram mode (on-line sorting and accumulation of spectra in the internal memory) and list mode (accumulation of raw data immediately on a computer disk). 1.Sonix+, http://sonix.jinr.ru 2.A.Belushkin et al. 2D Position-sensitive detector for thermal neutrons.
