Talks

The working groups 'Calibration', 'Readout and Data Transfer' and 'Electronics' had during the workshop combined parallel sessions. You can find the presentations of the combined sessions at A1.4 and A2.4.

      MISSION STATEMENT

The main purpose of the readout system is to convert the (analogue) signals from the photo-sensors into a readable input for the off-line analysis. As much as possible of the (raw) data should be transmitted to shore, where different physics signals should be filtered from the data online with the highest possible efficiency. At the same time, the main background from random noise should be reduced to an acceptable level. The main requirements for the off-shore part of the system are low power consumption and high reliability (e.g. as few connections as possible), and for the on-shore part flexibility and extendibility. The filtered data should be distributed to the various institutes and analysed in real time.
