Neutron Proportional Detectors

BF3 Neutron Proportional Detectors

MODEL DIAMETER ACTIVE LENGTH OPERATING VOLTAGE GENERAL SPECIFICATIONS

G-5-1 5/8" 1" 1400 to 2100 volts, for 20 to 60 cm Hg. MHV connector. Widely used in portable instruments. ALMOST UNLIMITED LIFE
GUARANTEED FOR ONE YEAR

ENRICHED BF3. (99% BORON 10) specify Model G.

FOR DEPLETED BF3 (11% BORON 10) specify model F.

200 VOLT PLATEAUS with 1% slope per hundred volts in best part of plateau.

BACKGROUND OF < 7 COUNTS PER HOUR for Model G-10-12, less for smaller sizes.

CONSTRUCTION IS RUGGED. Counters are made to withstand shock and vibration.

NEUTRON SENSITIVITY for a Model G-10-12 filled to 40 cm is approximately 5cps/n/cm*2/sec. It is higher for higher pressures or larger sizes.

ARGON may be used with BF3 in any proportion specified.

G-5-3 5/8" or 1/2" as specified. 3" Caps same O.D. as counter. Small general purpose neutron detectors.

G-5-9 9"

G-10-2A 1" 2" 1800 v. for 60 cm Hg. MHV connector. Widely used in portable instruments.

G-10-5 1" 4 1/2" 1500 v. to 2200 v. for 20 to 60 cm Hg. For lower oper. volt. specify small dia. anode. Standard multiple purpose neutron detectors.

G-10-8 1" 8"

G-10-8GL* 1" 8" Graphite Lined BF3 Detectors

G-10-12 1" 12 1/2" Standard multiple purpose neutron detectors.

G-10-20 1" 20"

G-15-5 1 1/2" 5" 1700 to 2250 v. for 20 10 45 cm Hg. Higher pressure may be specified as well as lower voltage. MHV connector. Standard research counters. High sensitivity low background.

G-15-12 1 1/2" 12"

G-15-20 1 1/2" 20"

G-15-34A 1 1/2" 34" [G-15-34A was developed for cosmic radiation studies (Simpson counter).]

G-20-5 2" 5" 1900 to 2300 v. for 20 to 45 cm Hg. Higher pressure and lower voltage may be specified. General purpose high sensitivity detectors. Useful in moisture meters and environmental monitoring. Connectors same as above models.
