R5600U + E5780 |
 CLICK to Visit Hamamatsu for specs.
Hamamatsu The R5600U is a super-compact photomultiplier tube in an OPTO-8 package. The bialkali photocathode is 8 mm in diameter and the outer PMT diameter is 16 mm. The metal channel eight stage dynode allows for a very small over-all package which can be used where no other PMT can fit. Gain is 3 x 10^5 at 800V and a peak quantum efficiency of 15% (at 400 nm). These include the Hamamatsu E5780 voltage divider base assembly, which is described in the data sheet below. Risetime, falltime and pulse width are approx. 650, 1050, and 1500 psec. Transit time spread of 280 psec FWHM at 800 V with a single photoelectron event, response time of the PMT is 0.65 ns. Spectral range is 300-650nm, Bialkali photocathode. FULL R5600 PDF FACTORY DATA IS HERE. These are all excellent condition known good pulls, look like new.
