| PEA-6A |  Preamplifier for Proportional Counters |  |  Preamplifier and Amplifier in compact housing
Designed for operation with proportional counters Bipolar output pulses
The PEA-6A combines a charge-sensitive preamplifier for proportional counters and an main amplifier in a very compact housing. The main amplifier is designed for count rates which are typical in Mössbauer spectroscopy. Its bipolar output can be directly connected to the analog input of a CMCA-550 or CMCA-650. For supplyingpower to the PEA-6A, special adapters for NIM Bins are available. |
