Abstract:
The photocathode of solar-blind photomultiplier tube is Te-Cs, and the glass tube is synthetic quartz. We use special oven with two lights to prepare solar-blind photomultiplier tube. We test the performance of solar-blind photomultiplier tubes. Results show that CR340 has good solar-blind characteristic, cut-off wavelength at 320 nm, and output sensitivity can reach 5×10
5 A/W (250 nm), and gain can reach 1.3×10
7, and life is more than 1000 h. Solar-blind photomultiplier tubes are evaluated by several domestic analytical instruments manufacturers, all feedback are very good.

We test the performance of solar-blind photomultiplier tubes. Results show that CR340 has good solar-blind characteristic, cut-off wavelength at 320 nm, and output sensitivity can reach 5×105 A/W (250 nm), and gain can reach 1.3×107, and life is more than 1000 h. Solar-blind photomultiplier tubes are evaluated by several domestic analytical instruments manufacturers, all feedback are very good.
