Preamplifier Options
Amptek's FAST SDD® is available with the XR-100
preamplifier, with the PA210 or PA230 OEM preamplifiers,
or as part of the X-123 and X-55.
Signal Processing Options
Amptek's FAST SDD® may be used with Amptek's DP5 or
DP5-X, or the PX5, or as part of the X-123 or X-55.
Specification Notes
Performance listed here is measured at full cooling (<220K).
The "peak to background ratio" is the ratio of counts in the
Mn Kα peak channel to the counts at 1 keV.
"Gain stability" refers to the change in sensitivity when the
preamp temperature changes but the detector temperature
is stable.
Operating Notes
Detector must be operated with an appropriate heat sink.
The FAST SDD® is suitable for vacuum applications. Amptek
provides several system configurations.
