Description

CANBERRA's SafePoint iR7040 intelligent, wall-mounted ratemeter is a digital ratemeter ideal for use in a variety of inplant area and process monitoring applications. The configurable and versatile design of the iR7040 eliminates the need for costly customization and minimizes maintenance requirements, thus saving time, expense and radiation exposure for users. The iR7040 can be configured to operate autonomously, or as part of an integrated monitoring system. This versatile unit is designed to power and control up to four CANBERRA radiation detectors of any style or application, making it suitable for use in Nuclear Power Plants, Research Reactors, Fuel Cycle Facilities and other facilities that can benefit from advanced radiation monitoring.

The ratemeter connects with inputs such as pressure, temperature, and flowrate used to generate corrected data such as total dose, activity concentration, filter activity loading, and activity discharge rates. The iR7040 will support any reporting requirement and radiation or activity unit of measure.

The iR7040 has been designed to simplify operation and maintenance for the user. Its large industrial color touch-screen interface is readable under adverse lighting conditions and provides the user with enhanced field functionality. The detachable termination panel of the iR7040 can be easily separated from the ratemeter for convenient interconnection to plant systems as well as quick and easy ratemeter exchange.

The iR7040 ratemeter logs all data; Alarms, Probe outputs, Probe parameters, conditioned outputs, source check responses, and out-of-parameter conditions to its internal histogram for plotting and enhanced performance monitoring. Performance and reliability are assured through the ratemeter's rigorous self test functionality.

The ratemeter serial number and manufacturing date are burned-in at the time of manufacture. All measurements and log data are tagged with it. This feature makes supporting the traceability of calibrations, testing, performance plotting, measurements and trending an automatic affair. Configuration management and Maintenance rule requirements become much easier when the iR7040 is used.

The iR Ratemeter supports an enhanced Source check functionality, allowing the user to manually or automatically perform source checks of attached probes and detectors with that capability. The source check results can be plotted for long term performance and stability verification. Individual tests can also be compared to the expected value to alarm on out of specification responses.

The iR7040 also offers greatly simplified calibration routines and software/database tools. Access to Calibration statistics is readily available, and the system tracks calibration sources, activity (original and decay corrected to time of test). Automated Chi-Square functionality is also available.

GP Series - Geiger Mueller Detectors

GP Series - Geiger Mueller Detectors

Description

A pair of rugged halogen-quenched GM detectors serves as the basic detection elements in the GP Series detectors used for wide range gamma radiation measurement. The GM detectors operate under CANBERRA's unique Time-to-Count technique which removes many of the limitations associated with the use of GM detectors operated in conventional mode.

In addition, the GP Series of detectors are SMART probes, which retain probe information in nonvolatile memory. When calibrated, data such as probe calibration constants and identifying information are stored and verified in the EEPROM memory in the probe circuitry. This arrangement allows the CANBERRA GP Series detectors to be interchangeable.

The GP Series of detectors are "maintenance free" in design and require no routine servicing or preventive maintenance.

The GP100C/GP100C2 and GP100CS/GP100C2S detectors have an internally mounted (nominal) 3.7 kBq (0.1 µCi) 90Sr Check Source Assembly.

The GP100M and GP100MS are used in conjunction with a preamplifier, PA100M. This arrangement allows components that are susceptible to damage by extended exposure to radiation to be placed up to 200 feet away from the detectors.

The GP Series can be connected to multifunction control and display unit such as iR7040, ADM606, ADM606M and ADM616.

ADM606M Portable Multifunction Ratemeter/Scaler

ADM606 Rackmount Multifunction Ratemeter/Scaler

ADM606 Rackmount Multifunction Ratemeter/Scaler

Description

The ADM606 is a microprocessor controlled digital ratemeter, designed to power, control and process data from various types of CANBERRA radiation detectors. The ADM606 can operate with both area and process monitoring detectors for measurement of many types of low and high intensity radioactivity. The area monitoring detectors are designed for open area detection of gamma or neutron radiation. Process monitoring detectors detect alpha/beta/gamma activity and are designed to mount in fluid or gas flow streams such as ventilation ducts, stacks or liquid piping systems.

The ADM606 is designed to take full advantage of the features of the CANBERRA "SMART" detector series, it also can operate with conventional detectors, or with a combination of conventional and "SMART" detectors. When coupled with the "SMART" detectors, the ADM606 interrogates each connected probe to determine the detector type and calibration constants, then automatically sets the display of measurement type and units for that measurement channel. This feature allows for quick detector swapout, and permits factory calibration of detectors rather than time consuming in-field calibration of each monitoring station.

The ADM606 can be installed as one of a total of three units mounted in a 19 in. wide by 7 in. tall CR600 NIM style rack. The ADM is interfaced directly to a Rear Termination Panel Assembly, CR600TP. The CR600TP and optional CR600CIP, Customer Interface Panel, provides terminal blocks connections to relay contacts, communication ports, and analog and digital inputs/outputs.

The ADM606 provides the following user interface features: 2 lines x 20 characters vacuum fluorescent display, six button membrane switch keypad, three position key switch, four LED indicators, and a RS-232 serial port.

The ADM606 also provides the following control and communication circuitry with connections made through the Termination panel, CR600TP: Eight Single Pole Double Throw (SPDT) relays.

The optional Customer Interface Panel, CR600CIP provides terminal block connections for: Five Double Pole Double Throw relays (DPDT) and one Single Pole Double Throw relay, four Isolated 4-20 mA analog outputs and three Isolated RS-485 communication ports. The Analog Outputs are proportional to the dose rate for area monitors or count rate/concentration for process monitors.

The ADM606 allows configuration of the alarms to be latching or non-latching and to configure the alarm relays as normally energized (de-energized on alarm, failsafe) or normally de-energized (energize on alarm).

In latching mode, the alarm indicators continue to indicate alarm until after the rate drops below the alarm setpoint and the operator has pressed the Reset button. In non-latching (or tracking mode), the alarm indicators automatically reset when the rate drops below the alarm setpoint.

When used in the local configuration, ADM606 supports CANBERRA's unique Time-to-Count technology and LED-based gain stabilization for scintillation detectors for enhanced RMS performance.

The ADM606 can be used in a remote configuration in a control room where it can interface with other field-installed ratemeters such as the iR7040, ADM606M, ADM616 or Tritium Monitors such as the TAM100D/T100DSI, or TAM73D/T73DSI.

Neutron Detectors - NP Series

Neutron Detectors - NP Series

Description

The NP Series provides customers with the capability of detecting slow and fast neutrons and measurement of tissue equivalent dose rate of the neutron field. The detectors contain a proportional counter which produces pulses resulting from neutron interactions within it. The probes contain components which moderate and attenuate neutrons so that the net incident flux at the proportional counter is a thermal and low epithermal flux representative of the tissue equivalent dose rate and the neutron field.

The neutron probe also contains a Circuit Card Assembly (CCA), Amplifier and Logic, and a CCA High Voltage supply.

The NP Series detectors are SMART probes, which retain probe information in non-volatile memory. When calibrated, data such as probe calibration constants and identifying information are stored and verified in the EEPROM memory in the probe circuitry. This arrangement allows the CANBERRA NP Series detectors to be interchangeable.

The NP Series detectors are "maintenance free" in design and require no routine servicing or preventive maintenance.

The NP Series can be connected to multifunction control and display units such as iR7040, ADM606, ADM606M and ADM616.

Principle of Operation

Because neutrons have no charge, they can only be detected indirectly through nuclear reactions that create charged particles. The NP100B detector uses BF3, whereas the NP100H uses ³He as the conversion target. The charged particle – alpha or proton (respectively) created in the nuclear reaction ionizes the gas.

The detector is housed in a polyethylene moderator with high hydrogen content. The hydrogen presents a large scattering section to the neutrons. Through elastic collisions with the hydrogen atoms the fast and epithermal neutrons give up a large part of their energy and are reduced to thermal neutrons.

A cylindrical attenuator containing 10B isotope surrounds an inner moderator which contains the proportional counter.

The thermal neutron flux densities resulting from the moderation by the detector housing are attenuated as a result of the high absorption of the 10B. Neutrons which are not thermalized and which are not attenuated will be thermalized by the inner polyethylene moderator.

The combined effect of the 2.25 in. thickness of 10B attenuator and 0.75 in. thickness of the inner polyethylene moderator gives a probe pulse rate output proportional to the tissue equivalent dose rate of the neutron field. See Figure 1 for a curve of actual vs. theoretical response.

The NP100H uses a ³He proportional counter consisting of a cylindrical metal shell with a center anode wire maintained at a high positive potential with respect to the shell. 3He gas is contained within the shell and the neutrons are detected by their nuclear interaction with the helium. The thermal neutron-helium reaction produces a charged particle (proton) which ionizes the gas.

Respectively, the NP100B uses a BF3 proportional counter consisting of a cylindrical metal shell with a center anode wire maintained at a high positive potential with respect to the shell. Boron-trifluoride gas is contained within the shell and the neutrons are detected by their nuclear interaction with the BF3. The thermal neutron-boron reaction produces a charged particle (alpha) which ionizes the gas.

The ionization event causes a burst of electrons to arrive at the center anode wire. From this point, the charge produced by the burst of electrons is coupled by an interconnecting cable to the input of the charge sensitive amplifier.

The NP Series detectors are used with the CANBERRA Model iR7040, ADM606, ADM606M and ADM616 series of digital ratemeters. These instruments provide low operating voltages to the detectors while displaying the count rate from them. High voltage necessary for the proportional tube operation is produced via a circuitry inside the detectors allowing use of low voltage cabling.
