The BURLE-6199 is a 10 stage, end-window, 38-mm (1 1/2-

inch) type of photomultiplier intended for use in scintillation

counters and for the detection and measurement of low-level

radiation. The tube features excellent time resolution character-

istics, high current amplification, and high sensitivity making it

an appropriate choice for applications requiring low-light level

measurements. The flat faceplate enables the user to easily

couple to a scintillation crystal. BURLE 2060 is a 1-1/2-inch

diameter, 10-stage, head-on type of photomultiplier tube having

S-11 spectral response. It is identical to BURLE 6199 in all

respects except that it is supplied with a small-shell duodecal

base attached to flexible leads to facilitate testing. After testing,

the attached base should be removed prior to installing the 2060

in a given system.
