PETsys Time-of-Flight Data Acquisition Board

Figure 1: Picture of the DAQ board.

 

   The PETsys TOF DAQ board (Fig. 1) is a PCIe based data acquisition board that collects data from front-end FEB/D boards. Each FEB/D board collects data from sixteen TOF ASICs in eight FEB/A boards (1024 channels). Up to twelve master FEB/D boards can be connected to the DAQ board using HDMI cables, or using optical fibers. A master FEB/D can be daisy-chained with several slave FEB/D boards.

 

   Therefore the DAQ board and the FEB/D boards together form a complete and calable data aquisition system that can handle tens of thousants of SiPM channels.
