P multiplication by secondary emission. & br / this multiplier 10 to secondary emission of electrons is composed, on the one hand, a first metal plate 11 pierced with at least one hole 12 multiplier, having an opening 13 of the input and an opening 14 of the output, and, on the other hand, a second metal plate 16, parallel to the first 11, provided with at least one hole 17 auxiliary disposed facing the opening 14 of the output of multiplier 12, the second plate 16 is connected to an electrical potential v1, greater than the electrical potential v0 of the said first plate. The openings 13, 14 are such that the straight projection 18 of the opening 14 of the output of multiplier 12 on a plane parallel to the first metal plate 11 is at least partially located outside the corresponding projection 19 of the opening 13 of the input. & br / application of the photomultiplier tubes. & br / (see appended drawing in bopi) & br / & & br / / p
