As a part of Gammasphere's upgraded DAQ system, a new "collector box" has been added. The collector box collects and maps all analog signals for up to 30 detectors, coming from the pickoff card in the SBX to the collector, and being output to the digitizers. For concepts like "electric honeycomb", the collector box implements distinct hardware to accurately route signals to the digitizer. It does this this by utilizing time synchronization with its access to the trigger system to ensure that the correct set of samples are used for the reconstruction of each BGO waveform. Control and monitoring of Gammasphere's modules are maintained with the help of the collector box, using EPICS IOC. It provides power to individual SBX units via a singular 48V input from the power supply (above the circled collector box in the image to the right).
