DAQ and Controls 



The CAPTAN has been redesigned to service many applications at Fermilab and in the laboratories of our collaborators at the Purdue University , the University of Coloardo, at Milan and Torino in Italy. The US CMS pixel community is using it to take data in laboratory environments and in the test beam at the Fermi Test Beam Facility (FTBF). At FTBF, the Fermilab Silicon Pixel and Strip telescopes are read out by the CAPTAN system.

CAPTAN+X (“CAPTAN plus X”) is the next generation CAPTAN card. 

  • A leap from Xilinx 4 series to 7 series.
  • The ‘X’ stands for “eXtreme” for its support of 10G links. 


  • Gigabit Ethernet
  • 4 FMC connectors 
    • 2 HPC, 2 LPC
    • High-speed Links per FMC: 
      • SE=10, NW=4, NE=1, SW=1.
  • 400 GPIO
  • 12V Input Power Block


FTBF Strip Telescope

  • The Real-time Systems Engineering Department has delivered solutions for high resolution tracking at the Fermi Test Beam Facility (FTBF).
  • Old pixel telescope DAQ is based on CAPTAN and was Triggered, 2.5cm2 coverage, and 8µm track resolution.
  • New strip telescope is based on CAPTAN too, but it uses 60µm strips (4cm x 9cm) left over from D0. It features dead-timeless readout, 16cm2 coverage, and less than 5µm track resolution.
