DESCRIPTION:Speakers: Dmitry Finogeev ()\nA new highly granular time-of-fl
 ight neutron detector (HGND) is being developed and constructed for the BM
 @N (Baryonic Matter at the Nuclotron) experiment to identify neutrons and 
 measure their energies in heavy-ion collisions at beam energies of up to 4
  AGeV. The HGND consists of two arms\, each with 8 active layers\, each of
  11×11 plastic scintillator cells 4×4×2.5 cm³ with direct light readou
 t by silicon photomultipliers EQR15 11-6060D-S and copper absorber plates 
 with thickness 3 cm in between. The detector readout electronics is based 
 on a custom-developed board featuring a 100 ps FPGA-based time-to-digital 
 converter (TDC). The complete HGND readout system will comprise eight such
  boards\, each equipped with three Kintex-7 FPGAs and capable of reading o
 ut 248 channels.\nA fully functional 34-channel detector prototype\, corre
 sponding to one quarter of a single active layer\, was tested using cosmic
  muons and the LPI electron beam. In addition\, a two-channel prototype wa
 s integrated into the BM@N data-acquisition system\, including full-chain 
 readout functionality\, and tested during the run in April of this year.\n
 Details of the HGND development\, readout topology and test results will b
 e presented.\n\nhttps://indico.particle.mephi.ru/event/626/contributions/6
