DAQ rate management, neutron ToF
Diagram (above) of the FEE boards as they would fit in the vertical plane. The grey rectangles are heat conductive foam pads which conform to the component outlines and conduct the heat to the water cooled metalwork. The green is pcb, the orange is a Samtec 80 pin connector with a 2.3mm height and the dark brown is the ASIC. The connections to the detector will be on the mezzanine boards to the left and to the acquisition network computers and BUTIS on the right. These are not shown.
Diagram ( alongside) shows the layout of a sub-board.
