Description
BM@N experiment at NICA in Dubna is currently being upgraded for the study of dense nuclear matter in heavy-ion collisions. One of the major upgrades is a new hybrid tracking system consisting of the large-area Silicon Tracking System (STS) and seven GEM planes [1]. STS is based on the modules with double-sided microstrip silicon sensors of CBM-type. The data driven acquisition system of STS is relying on self-triggering readout channels and data processing chain is adopted for the operation with BM@N trigger [2].
The core components of the readout chain are Front-end Boards (FEB), GBTxEmulator board and GBTxEmulator 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 GBTxEmulator board based on FPGA which emulates functionality of the CERN GBTx ASIC [3] and provides a bidirectional optical link between front-end electronics and data processing boards in the server nodes. The GERI board concentrates and pre-processes the data stream, filters the data according to the BM@N trigger signals and provides an interface to configuration and control of the readout electronics.
For the needs of integration into the global BM@N DAQ a trigger-based data filtering was developed and implemented. Methods of integration and synchronization of the STS readout chain with the common data acquisition system BM@N experiment are described.
Front-end electronics, electrical connections, data concentrator and architecture of data processing board are described in the report. The results of testing of a pilot version of the readout chain are presented.
