Abstract
The MPD Time-Projection Chamber (TPC) is the main tracking detector of the MPD experiment. Tracks coordinates are obtained by measurement of drift time of electrons from track position to readout chamber. The drift velocity of electrons can vary due to pressure, temperature, space charge effects, so it must be measured online. To solve this problem the laser calibration system is foreseen for this. The article presents an algorithm that provide drift velocity measurements and based on processing signal-in-time distributions.
