3.1 The Detector
The detector consists of a pressure vessel at
3.04 bar (3040 hPa, 3 ATM) with a back cover
(see Figure 3.1). The VÅNTEC-1 is a single
photon counting detector which converts the X-
ray photons to electrical signals. The signals are
amplified by three preamplifiers attached to the
detector. The high-voltage filter and preamps
are mounted into the back cover of the detector.
3.1.1 Detector Cables and Connectors
The back cover has six cable connectors:
• One connector for the preamplifiers’ low
voltage power supply
• Two cables for the detector’s high-voltage
supply
• Three signal outputs for the preamplifiers
Ten cables are delivered with the detector (see
Table B.1 for part numbers):
• Ethernet crossover patch cable with RJ-45
connectors
• Power cable
• Motor clock cable
• Serial cable
• Three 15 ft (5 m) preamp cables (Ch 1,
Ch 2, Ch 5)
• Low-voltage (detector) cable
• Power cable
For configurations with an external FDC, an
additional power cord, serial cable, and TDC to
FDC data cable are included.
Table 3.1 summarizes the detector specifica-
tions.
