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.
