ANTECH
Plutonium Scrap Multiplicity Counter
Model 2108
Benefits
·
Very high efficiency (>50%) for
the detection of 240Pu spontaneous
fission neutrons
·
Designed for energy dependence of
the detection efficiency as small as
is reasonably practicable
·
Designed to have as flat a radial and
axial detection efficiency profile
·
Large measurement chamber: will
accept sample containers having
maximum dimensions of 200mm
(diameter) 400mm height (7.9 in.
15.7in.)
·
Transportable passive neutron
measurement chamber mounted on
robust trolley with locking castors
for safety and stability
Features
·
Designed for quantitative passive neutron measurement of scrap and residues based on
the Los Alamos National Laboratory design,
Sample cavity size 200mm (diameter) × 400mm height (7.9 in. × 15.7in.)
·
·
Coupled to the ANTECH/ORTEC AMSR-150 with INCC-B32 software or the AN-
TECH Model 1003 TCA with ANTECH TCA Scientific Software for multiplicity distri-
bution data collection
·
Fast Amptek A-111 based amplifier/discriminator based junction box reduces dead time
effects for doubles and triples especially at high count rates
·
The annular ANTECH electrically screened Junction Box ensures comprehensive elec-
trical screening at the termination of the detector tubes
·
ANTECH De-randomizing Buffer Mixer Counter provides a buffer so that pulses which
arrive 'simultaneously' on different inputs are not lost
80 × 3He tubes (25.4mm outer diameter × 711 mm active tube length, 4
·
atmospheres fill pressure) arranged in four concentric ring
