2. Dry Run & Technical run Technical Run TDAQThe October Technical Run is a good opportunity to test the TDAQ structure and to readout data for detector calibration. complex systemThe TDAQ is a relatively complex system. all electronics equipments Dry RunJuly 15To better take advantage of the beam time available, it’s mandatory to test all electronics equipments that will be used in the technical run  Dry Run will start July 15 (for 1 month) no interferenceSome amendment to this law is possible in case of no interference with other systems.

3. TDAQ concepts same FPGAsFor most of the detectors the readout and the definition of trigger primitives is done with the same FPGAs. primitivesasynchronous trigger decision synchronous.The primitives trigger transmission is asynchronous while trigger decision transmission is synchronous.
