There are several programming tools that optimize a DACQ, the IPCS(Inter Process Communication) POSIX, the std template libraries, as the parallel programming, that become mandatory to produce a DACQ with high computing demand. New sampling ADCs allow as to have Trigger less or self trigger DACQ where the event as a group of signals due to a trigger in a predefined time window corresponding to a physical event do not exist any more. In a TL system the the signals are independent and has a time-stamp to reconstruct a “posteriori” the physical events. Our GasificTL is a Data acquisition system that is able to work in a self trigger mode, and is able to work with physical event with huge duration (hundreds of micro, neutron moderation tie in polyethylene) with death time around of 3micros.
