Abstract

For the calibration and monitoring of scintillator based time-of-flight systems, fast laser pulses, delivered to the individual channels, may be used. Low-cost laser diodes with FWHM time resolution in the range 30-50 ps may be chosen as light source. The problem is their low output power, as compared to traditional solutions as expensive duplicated Nd-Yag lasers. The tests done to assemble a prototype system based on optical switches and fiber fused splitters will be summarized, as well as the ones on the full-scale prototype. The main concern was the tight power budget of the system.
