Hamamatsu Introduces Three New High-Speed Photomultiplier Tubes for Scintillation Counting

Bridgewater, New Jersey – August 6, 2007 – Hamamatsu Corporation will exhibit three new photomultiplier tubes (PMTs) with excellent time resolution characteristics at this year's Nuclear Science Symposium in Honolulu, Hawaii from October 30 to November 1.

The R9800, R9420, and R9779 each features an extremely short transit time spread that is uniform across the entire effective area of the photocathode. The photocathode is bialkali material with a spectral response range of 300 nm to 650 nm. Peak sensitivity is in the blue region of 420 nm, which makes these PMTs ideal for scintillation counting. Intended applications include time-of-flight PET in nuclear medicine, time-of-flight counting in high-energy physics experiments, and radiation monitoring in security instruments.

The new high-speed PMTs share a simple head-on design that is suitable for mass production, but differ in terms of their size and other specifications. The R9800 has a 25 mm diameter, and provides gain of 1.0 x 10⁶ with a rise time of 1.0 ns and transit time spread of 270 ps. The R9420 is a 38 mm PMT that provides gain of 5.0 x 10⁵, rise time of 1.6 ns, and transit time spread of 550 ps. With the R9779, which has a 51 mm diameter, gain is 5.0 x 10⁵, rise time is 1.8 ns, and transit time spread is 250 ps. The supply voltage required is either 1300 V (R9800, R9420) or 1500 V (R9779).
