The ANTECH Network Neutron Counter, Model N2000-2 combines Total Neutron Counting, Shift Register Coincidence Counting and Multiplicity Counting in a portable package to provide a state of the art instrument. The N2000-2 offers the benefits of immediate measurement results provided by the instruments real-time software, displayed on the front panel touch screen. The 512 channel multiplicity histogram information, saved on an internal flash-drive can be re-analysed as necessary.


Mounting Options

The N2000-2 is designed to be mounted in a standard 19″ rack. It can be mounted as either a single unit, or as two units side by side. For a single unit, a blanking plate connects to the side of the rack. For dual mounting, brackets connect both units. All cable connectivity is provided on the rear of the unit, allowing for easy installation and removal in a 19″ rack.


  • Capable of standalone use with or without an external computer
  • Fully attended capability through Ethernet and INCC compatibility
  • Automatic High Voltage Plateau measurement
  • Compact portable design
  • Multiple inputs - up to 4 TTL (BNC) of which two can be configured as external scalers
  • Powered via 12Vdc mains adaptor
  • 19" rack compatible with mounting kits holding a single unit or two side by side


  • High frequency 50MHz acquisition clock for high accuracy
  • 4 BNC input connecters
  • Built-in 4 input De-Randomizer Buffer Mixer (DRBM)
  • High Voltage Supply for ³He neutron detectors - max. 2000jVdc (max. 2mA)
  • Low Voltage 5Vdc supply for amplifier boards (max. 2A)
  • 2.4" touch screen for stand-alone operation to set parameters, start measurements and readout results
  • Automatic High Voltage plateau measurement
  • Remote operation using INCC or other compatible clients
  • Access to results (INCC format and N. 42 format) logfiles and default setup file via external PC using LAN or WAN (Samba protocol)
  • 1.5 GByte internal storage for results and log information
  • Description

    The unit has four BNC input connectors with current single TTL output neutron counting systems such as a Neutron Coincidence Collar. Each input is equipped with a de-randomising buffer (5-bits) and can accept short bursts of incoming pulses with a maximum frequency of 50MHz.

    the N2000-2 also provides a High Voltage output, which can be set in a range of 0-2000Vdc and is provided through an SHV output bulkhead. The High Voltage output is controlled through a software swich in the system setup and is inhibited by a hardware switch on the front panel. The HV status is indicated by a red LED.

    The N2000-2 has a built-in control and analysis computer and a 2.4″ touch screen for system and measurement set up, for displaying results and for setup and analysis of a fully automatic high voltage plateau measurement. This enables the unit to act as a standalone instrument without the requirement for any external computer.

    the N2000-2 is fully compatible with the INCC in AMSR mode via serial to Ethernet conversion, and the provision of analysis results both in INCC format and as ANS/IEEE/IEC N.42 files on a network served flash drive makes the N2000-2 ideally suited for remote operation over local or Wide Area Network using the built-in Ethernet Port.
