AMP-1000
Spectroscopy Main Amplifier

Model AMP-1000 is a spectroscopy main amplifier, well suited for Mössbauer spectroscopy.
It can be used together with proportional counter LND-45431 and and with our preamplifier PEA-6.
Furthermore it is suited for backscatter experiments with our CEMS detector RiKon-5
It is performed a a NIM module. A 9 pin-SUB-D connector at the backside can be used to supply a preamplifier with power.

Features:

Accepts positive and negative input pulses

Bipolar output pulses

Selectable shaping time

Single width NIM module

Preamplifier power output
