  1. Seminar topic: “The quality assurance test system for series assembly of STS modules for the BM@N experiment”

    Speaker: Aleksei D. Sheremetev

    Abstract:

    The Silicon Tracking System (STS) of the BM@N experiment will be based on modules with Double-Sided microstrip Silicon Detectors (DSSD) which have been initially developed for the CBM experiment at FAIR. Each module consists of a DSSD, two front-end boards with 8 ASICs each, and a set of low-mass aluminum microcables. During the module assembly the microcables are tab-bonded to the sensor and readout ASICs. The module has 1024 channels on each side. In this seminar will be presented the quality assurance procedure that was implemented for the ultrasonic bonding process based on the noise per channel measurements carried out in a Pogo pin testing device.

  2. Seminar topic: “Construction management information system at JINR”

    Speaker: Alejandro Rodíguez Álvarez

    Abstract:

    The commissioning of an all-around Construction Management information System (CMIS) was recently completed as a joint effort of two JINR Laboratories (LHEP and LIT). The system is particularly useful for the fine-grained control and continuous feedback of the production of complex multipart objects like the detectors subsys- tems composing the MPD and BM@N experiments of the NICA facility at LHEP. Currently, the CMIS is meant to be used to follow the production of silicon tracker detectors at the STS department of the LHEP at JINR, although it would as well be used by any other hardware production projects related to JINR whose complexity would make it very hard to fulfilling its quality and timing requirements otherwise. In this seminar the current implementation on this system of the projects for the construction of the silicon trackers for the MPD and BM@N experiments, respectively will be presented.
