EMULATION AND CALIBRATION OF THE SALT READ-OUT CHIP FOR THE UPSTREAM TRACKER FOR MODERNISED LHCb DETECTOR∗

The LHCb is one of the four major experiments currently operating at CERN. The main reason for constructing the LHCb forward spectrometer was a precise measurement of the CP violation in heavy quarks section as well as search for a New Physics. To obtain interesting results, the LHCb is mainly focused on study of B meson decays. Unfortunately, due to the present data acquisition architecture, the LHCb experiment is statistically limited for collecting such events. This fact led the LHCb Collaboration to decide to perform far-reaching upgrade. Key part of this upgrade will be replacement of the TT detector. To perform this action, it was requited to design new tracking detector with entirely new front-end electronics. This detector will be called the Upstream Tracker (UT) and the read-out chip — SALT. This note presents an overall discussion on SALT chip. In particular, the emulation process of the SALT data preformed via the software written by the author.
