For its detection medium, this project uses a mixture of He:CF$_4$ at 1 atm, a low-density gas sensitive to both spin-dependent and independent interactions. The searches will focus on the detection of low mass (0.5-50 GeV) WIMPS and, eventually, solar neutrino spectroscopy. We are going to discuss the CYGNO/INITIUM experiment, a recent Dark Matter (DM) project focused on developing a new and innovative approach for directional DM searches: a high precision, optically readout, 3D tracking gaseous Time Projection Chamber. We will discuss a number of the microchips and related circuits and present results on performance that we have measured so far and possibilities for improvement. ![]() At Nalu Scientific, LLC we have designed such digitizer microchips, hardware, firmware and software to readout a variety of these sensors. One method to get the most performance out of such sensors is to use waveform digitizing electronics to capture the electronic pulse output and then post-process them locally or remotely to extract desired features such as time of arrival or the amount of charge at accuracies that are interesting for the experiments. The pulse amplitude, source driver impedance, physical density and cross talk characteristics of these detectors normally vary and can create challenging environments for optimum readout electronics. What most of these sensors have in common is electrical outputs in the form of a pulse with medium to fast rise times (0.2-2ns) and rather short pulse duration (0.2-4ns FWHM). (LAPPDs) and low gain avalanche photodiodes (LGADs). Multi-channel plate photomultiplier tubes (MCP-PMTs), large area picosecond photo multipliers Examples of such sensors include silicon photomultipliers (SiPM), ![]() Timing resolution measurements of phenomena related to high energy physics, nuclear physics andĪstro- particle physics experiments. ![]() Recent advances in photonic and radiation sensors and detectors has allowed high quality and high
