New Electronics for the Tracking System of the Spherical Neutral Detector at VEPP-2000

New electronics was developed and mounted in 2022 to digitize signals from the tracking system of the Spherical Neutral Detector at the VEPP-2000 collider of the Budker Institute of Nuclear Physics. It is based on flash analog-to-digital converters and field programmable gate arrays and is used for digitization at a signal sampling rate of about 200 MHz with a resolution of 12 bits. Data are transmitted from each board to the data acquisition system via Ethernet with the bandwidth of 1 Gbit/s. Thanks to this, the new electronics is significantly better than the previous version in terms of the maximum event recording rate, and events can be recorded at a rate as high as 1.5 kHz. A special algorithm for extracting the amplitudes and response times from oscillograms has been developed. Data acquisition has been carried out with the new electronics since 2023. The resolution measured for the parameters of reconstructed tracks meets the requirements of 0.82° for the polar angle and 0.38° for the azimuthal angle.
