摘要:

我们描述了一种具有单光子(电子)计数和成像能力的紫外光探测器。它是基于一个碘化铯光电阴极,GEM电荷倍增器和一个自触发CMOS模拟像素芯片与105k像素在50微米的间距。由吸收UV光子产生的单个光电子漂移到单个GEM孔内并在其内部倍增。GEM雪崩的坐标由像素芯片以高精度(4微米rms)重建。因此,GEM孔的地图,以50微米间距排列在三角形图案上,被精细成像。

英文摘要:

We describe a UV photo-detector with single photon(electron) counting and imaging capability. It is based on a CsI photocathode, a GEM charge multiplier and a self triggering CMOS analog pixel chip with 105k pixels at 50 micron pitch. The single photoelectron produced by the absorption of a UV photon is drifted to and multiplied inside a single GEM hole. The coordinates of the GEM avalanche are reconstructed with high accuracy (4 micron rms) by the pixel chip. As a result the map of the GEM holes, arranged on a triangular pattern at 50micron pitch, is finely imaged.
