3.1.2 Environmental Ratings
Table 3.2 shows the range of environmental
conditions for which the equipment is designed.

3.2 The Detector Controller
The detector controller currently has the FDC
integrated within the detector controller. Previ-
ous configurations have an external FDC unit.
Both configurations are discussed in this man-
ual.
3.2.1 Identifying Integrated and External
FDC configurations
Older detector controllers contain the electronic
circuit boards for signal processing, the detector
(high-voltage) power supply, a power supply for
the detector preamplifiers, the Constant Fraction
Discriminator (CFD) boards, the Time to Digital
Converter (TDC) boards, and all electronic
assemblies. All of these units are placed within
the same 19" housing as shown in Figure 3.4.
In these older configurations, the FDC is an
external unit.
Newer detector controllers have FDC controller
integrated within the detector controller chassis.
