Using ultra fast analog memories for fast photodetector readout
Abstract : The recent progresses in the field of photodetection have pushed the performances of the detectors toward the picosecond scale. Necessary precise charge and time measurement are mainly based on high-end oscilloscopes or commercial modules, but these solutions are expensive and house very few channels. The USB-WaveCatcher board provides high performances over a short time window. It houses two 12-bit 500-MHz-bandwidth digitizers sampling up to 3.2 GS/s. Its low consumption allows it to be USB-powered and it offers a lot of functionalities. The board has been used in different test benches dedicated to fast MCP-PMTs or SiPMs, and a reproducible time precision better than 10 ps rms has been demonstrated. Implementations with up to 16 channels have been designed and exhibit the same time precision. The USB-WaveCatcher thus seems to be a wonderful tool for photodetector characterization. Our next step is to widely expand the number of channels while keeping the 10 ps time precision.
