Preamplifier Options ORTEC provides an optional preamplifier for ULTRA- HIGH count rate
applications.
Ultra-High Count-Rate Preamplifier (PLUS Option)The ULTRA-HIGH Count-Rate Preamplifier (transistor-reset preamplifier)
which may be ordered as the "PLUS" Option, is available for GEM or GAMMA-X
detectors. This preamplifier, which can handle input count rates up to 1,000,000 counts/s
at 1 MeV, offers the added benefit of having no feedback resistor.
Ordering InformationPlace the word PLUS after the GEM, GMX model number. Example: To
order a 40% GAMMA-X (GMX) detector with resolution specification 1.95 keV, specify GMX40P4-76-PLUS.
NOTE: For the best results at low energies with small planar Ge
detectors, a Pulsed-Optical-Feedback (POF) preamplifier is recommended. Call the factory
for details.SMART-1 "Intelligent" Detector Option
To order, specify SMART-1 as a separate line item below the
detector specifications. |
