Abstract

The major upgrade of the BM@N experiment for the heavy ion program is a new hybrid trackingsystem. It consists of seven planes of GEM detectors and four silicon tracking stations based on the moduleswith double-sided microstrip silicon sensors of CBM type. The BM@N silicon tracking system (STS) willconceptually inherit the data acquisition system (DAQ) from the CBM silicon tracker currently in develop-mentforFAIR.Thisisanentirelydatadrivenacquis itionsystemrelyingonpurelyself-triggeringreadoutchannels, which will also be adopted for the operation with BM@N trigger. The core components of the read-out chain are front-end boards (FEB), GBTxEmu board and GBTxEmu readout interface (GERI) board.The front-end board is an integrated part of the STS module. The main components of FEB are eight STS-XYTER ASICs which are needed for the readout of one side of the silicon sensor. The GBTxEmu board com-prises an FPGA which emulates functionality of the CERN GBTx ASIC and provides a bidirectional opticallinkbetweenfront-endelectronicsanddataprocessingboardsinthecomputernodes.TheGERIboardimplements the following functionalities: concentrating and preprocessing of the data stream, filtering of thedata according to the BM@N trigger signals and providing an interface for the detector control system (DCS)to configure readout electronics.
