XIA provides everything necessary to build
a PXI system incorporating DXP-XMAP,
Pixie-4 or Pixie-16
modules. The total cost is very competitive, especially for systems
with many detector channels.
The following PXI products are available
for purchase:
- Crates and Controllers
from National Instruments are available for resale.
- XIA's PXI-PDM
provides preamplifier power for small systems and provides external
access to PXI trigger lines.
- XIA's XPPS provides
preamplifier power for large multi-element detector systems.
- The EHQxxx is
a PCI HV detector bias supply manufactured by ISEG, available
for resale.
The high speed of the PCI bus provides the
fast readout necessary for list-mode acquisition and scanning
applications. The flexibility of the customizable PXI connections
allows for synchronizing modules and events in multi-channel systems.
If possible, we strongly recommend limiting
all detector signal, communications and power connections to a
single instrumentation chassis, so as to prevent grounding and
shielding issues from arising.
Conventional detector systems typically include
a shaping amplifier, an MCA, preamplifier and detector power supplies,
and any number of gating or timing modules. When these components
are housed separately, each ground connection introduces a potential
source of noise. Unless carefully orchestrated, even a system
comprised of individually well-designed components will display
unwanted pickup due to ground loops and stray coupling.
Much of the problem is taken care of in DXP
and DGF systems inherently, as the shaping amplifier, MCA and
timing modules have already been reduced to a single printed circuit
card. Power supplies for the detector(s) and preamplifiers, as
well as ground connections at the detector must also be considered.
