VIAMP
OEM solution with VITUS CUBE SDD and low-noise preamplifier
The VIAMP-KC preamplifier module is a specially designed OEM printed circuit board for operation with KETEK’s VITUS CUBE Silicon Drift Detectors (SDD), matching all types from 7 mm² (H7) up to 50 mm² (H50) collimated area.
The assembly comprises an ultra-low-noise, ramped reset type electronic preamplifier of positive polarity with onboard settings and filtering for all necessary SDD bias voltages.
The Al housing is functioning as an appropriate heat sink. Beside KETEK’s standard housing, customized versions are available on request as well.
