2060
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.
