  1. Ethernet-driven control and data acquisition scheme for the Timepix-based TPC readout R. Degele, C. Kahra, U. Schäfer, M.Zamrowski Univ. Mainz

  2. TPC readout chain TPC to be read out by one or several pixel sensors (256*256 pixels) • Timepix chip bonded on a FR4 carrier • Amplifier • Discriminator • TDC • TOT • Common stop • Serialiser (LVDS link) • Flat cable connection (ZIF) to adapter board • Trigger, test pulse, voltage monitor • Flat cable connection to Xilinx ML506 evaluation board • FPGA Virtex-5 (XC5VSX50-TFFG1136) • Deserialiser • Buffer • Ethernet / IP packet engine (UDP)
