Description
Precise measurements on time intervals (TIs) are frequently needed in many physics applications such as particle detection. Time to Digital Converters (TDCs) perform conversion of TIs into a digital word. In the case of KM3NeT, thirty-one TDCs are used to discretize the photomultiplier output. Both the event width and the instant when it happens, require an accuracy of 1 ns. An oversampling technique has been used to achieve this resolution. The proposed TDC readout is based on a Field-Programmable Gate Array (FPGA) Xilinx Kintex-7 with low resource occupancy and controlled by embedded Lattice Micro LM32 processor. On the present article the TDC system is presented in detail.
