“…The field of view (FOV) is defined by multiplying the total number of pixels (NpixelsX • NpixelsY ) and the effective pixel area (d 2 ), here d is a onedimensional effective pixel size in specimen coordinate system. Until now all the efforts to raise the readout speed were devoted to the improvement of the microscope scanning systems, namely t image taking , t stage movement and Npixels [6][7][8]. However, the remaining parameter, d has been kept untouched.…”

Photographic emulsion is a particle tracking device which features the best spatial resolution among particle detectors. For certain applications, for example muon radiography, largescale detectors are required. Therefore, a huge surface has to be analyzed by means of automated optical microscopes. An improvement of the readout speed is then a crucial point to make these applications possible and the availability of a new type of photographic emulsions featuring crystals of larger size is a way to pursue this program. This would allow a lower magnification for the microscopes, a consequent larger field of view resulting in a faster data analysis. In this framework, we developed new kinds of emulsion detectors with a crystal size of 600-1000 nm, namely 3-5 times larger than conventional ones, allowing a 25 times faster data readout. The new photographic emulsions have shown a sufficient sensitivity and a good signal to noise ratio. The proposed development opens the way to future large-scale applications of the technology, e.g. 3D imaging of glacier bedrocks or future neutrino experiments.
