Fast, Seamless Integration
The TSA CM267 is a stand-alone conveyor monitor which can be positioned on the side or mounted directly above a moving beltway. The CM267 features highly sensitive detection for both gamma and/or neutron radiation. Designed to continuously screen moving items on a conveyor belt without the need for frequent calibration or maintenance, the TSA CM267 is intended for application in transportation centers where the relatively low energy emissions from 235U and 239Pu are the main concern. The CM267 also detects other radioactive isotopes present in threat materials. The TSA CM267 high sensitivity conveyor monitor offers reliable operation in variable background environments. This system covers most conveyor belt applications, and can be adapted to meet specific requirements.
Advanced Design Features
The TSA CM267 is a self-contained system housed in a single pillar with the gamma and neutron detectors for ease of installation and maintenance. An alarm output relay is standard which may be AC-coupled to stop or divert the conveyor automatically. The system is equipped with ethernet communications capability for integration with the operator interface. Programmable Detection Parameters Selectable settings for sensitivity, energy discrimination, and fault levels may be entered by the administrator.
Easy-to-Operate
In the field, after site preparation, the CM267 can be installed and operating in less than an hour. When powered up, the system first acquires an initial background, typically within 120-seconds and is ready to run indefinitely. When the CM267 senses items on the conveyor the system starts comparing the current count to the most recent background data. Alarm comparisons are made every 200ms. If the count exceeds the alarm level, both audible and visual alarms will be triggered. The system monitors itself and indicates low and high background conditions.
Flexible Detection Options
The TSA CM267 is available in three configurations; Gamma, Neutron or a combination of Gamma and Neutron detection. Gamma provides detection of ionizing radiation and Neutron provides detection of Special Nuclear Materials (SNM) while the combined Gamma and Neutron provides the most powerful detection capabilities for radioactive isotopes even in shielded materials.
Interface Options
With the optional Remote Alarm Panel operators can view alarms up to 300m from the monitor. The TSA CM267 is compatible with TSA RAVEN“ communications software designed to both capture and view data and video images relating to a radiological detection incident
Specifications
| Sensitivity |
Gamma: Will detect 10g of 235U (HEU) or 25g of 239Pu in 20 uR/hr background at a passage speed of one meter per second Neutron*: At a distance of1 m, will detect less than 200g of plutonium in a shielded container that reduces the gamma flux to 1% of the unshielded gamma flux. |
| Detectors |
Standard Gamma and Neutron: One 30 h x 6 w x 1.5 d in. (76 x 15 x 4 cm) organic plastic scintillation detector, shielded on four sides with 0.375 in. (10 mm) of lead provides approx. 270 in3 (4.4 liters) of detector volume per system. One, 2 in. diameter X 36 in. He3 tubes*.
High Sensitivity Gamma and Neutron: One 30 h x 6 w x 1.5 d in. (76 x 15 x 4 cm) organic plastic scintillation detector, shielded on four sides with 0.375 in. (10 mm) of lead provides approx. 270 in3 (4.4 liters) of detector volume per system. Two, 2 in. diameter X 36 in. He3 tubes*. |
| Alarm Indication |
Gamma alarms are indicated by a red strobe light mounted on the light tower; high and low faults by an amber light, and neutron alarms by a blue strobe light. Separate audio alarms are triggered for gamma and neutron alarm conditions. |
