Triggerless efficiency[edit | edit source]

The triggerless efficency has ben measured with one TIGER and one GEMROC. The acquisition was set in triggerless mode and the TP are generated by the GEMROC itself. The GEMROC generate N TPs after each Frameworld received from the chip. The time between the TPs is set by another parameter. This parameter was set to make the TP emission homogeneous with respect to the time
