BrilLanCe Series Integrated Design - Saint

Series
Integrated Detector Design
The integrated BrilLanCeTM detector design consists of a BrilLanCe 350 (LaCl3:Ce) or BrilLanCe 380
(LaBr3:Ce) crystal coupled directly to a specially selected photomultiplier tube (PMT). This is the
best design for applications requiring premium performance.
Standard Configurations –
Because of the high light output and fast decay time of
the BrilLanCe materials, PMT selection and integration as
well as the use of specific electronics are key to optimizing
performance.
Standard integrated designs are available with up to a 3"
diameter by 3" long. Larger designs can be produced upon
request. Associated electronics have been developed to
offer you a choice of designs optimized for spectroscopic
performance.
Table 1 summarizes standard configurations including PMT
diameter and typical performance. Tables 2 and 3 give the
electronics options to be used for each design. To continue
to serve your needs, new designs have been developed:
»»
elongated designs including BrilLanCe 380 crystal
1" diameter by 4" long well adapted when position
information is required by the application;
»»
X-ray detectors with thin crystals 2.5mm thick to serve
high count rate applications.

Integrated Detector Design
The results shown in Figures 1 through 6, and in Table 1 were obtained in our laboratories at room temperature with
standard modular electronics.
The BrilLanCe integrated designs are compatible with laboratory operation, which is normal pressure and humidity and
temperatures ranging from +4oC to +43oC.
