Neutron Generator Expertise


Neutron Generator Expertise

Thermo Scientific has been developing and manufacturing neutron generators for more than 50 years. With a proven track record in critical applications such as explosive and WMD detection as well as well logging and reactor starts, Thermo Scientific knows neutron generator technology.

One of our commonly used neutron generators is the field-proven P 385 model, which incorporates the latest in digital control. The P 385 is designed for longevity and lifetime cost savings. The P 385 has high neutron output, modern digital control, advanced functions, excellent economics, and a higher flux at the target plane and end cap. What is more, the P-385 has its high voltage power supply integrated which eliminates bulky, and potentially dangerous, external cables.

The P-385 accelerator head is U.S. DOT exempt, which allows it to ship fully pressurized, simplifying transport logistics and planning. 

Pre-Blending Stockpile Applications

One of the most popular uses of cross-belt online analysis systems is controlling stockpile chemistry to meet quality targets, thus ensuring smooth kiln operation and providing flexibility in quarry operations. Whether the stockpile is longitudinal or circular, the CB Omni allows consistent stockpiles, with minimal variations within and between piles.

Using optional software, quality control can be accomplished either automatically or with a person in the loop (manually). In either case, the analyzer tracks the chemistry of the stockpile compared to the target chemistry and determines the preferred proportions of the source raw material. 

Raw Mix Proportioning Applications

A primary determinant of kiln efficiency is the chemical uniformity of kiln feed. Kiln feed uniformity is in turn derived from the precise control of raw mix. Located downstream of the last raw mix component addition, a CB Omni Fusion provides the precise control needed to minimize raw mix variability while at the same time minimizing raw material costs and satisfying multiple quality control targets.

Using optional software, raw mix proportioning can be accomplished automatically with the system’s analysis triggering proportioning changes as frequently as each minute. The optional software accounts for varying time delays from the feeders to the analyzer and can accommodate multiple raw mix sources and control parameters. 

Unmatched Options and Flexibility

The CB Omni Fusion provides its users with many flexible options. One already mentioned is its ability to switch from one excitation source to another if costs, reliability or experience change.

Other options available are the number of detectors that can be specified. The more demanding the application, the more benefit may be derived from an increased number of detectors. The CB Omni Fusion accommodates one to four large volume Sodium Iodide (NaI) detectors. Because raw mix proportioning requires tighter precision and better “repeatability”, additional detectors can be specified if desired. Conversely, the modest repeatability needs of analyzers used for stockpile control may often use fewer detectors if desired.
As well, detector positioning is adjustable to allow additional optimization per application if desired. 

Additional flexibility comes in the form of multiple available configurations to accommodate various process conditions. The CB Omni Fusion can be tailored to optimize performance and fit a multitude of varied processes. The tunnel opening of each analyzer is customized to the specifics of the site considering belt width, idler angle, idler dimensions, surcharge angle, belt loading variation and material size. This practice ensures the most efficiency from its neutron sources, resulting in lower neutron flux levels to achieve a given accuracy target.

Finally, the most important feature is the user interface used to interact with the instrument. Our most flexible and configurable user interface to date is the powerful and unique Omni View software. 

Automatic Belt Load
Compensation (ABLC)
The CB Omni Fusion incorporates the unique Automatic Belt Load Compensation feature which ensures analyzer accuracy over a range of changing production rates and belt loading. As the material loading on the belt decreases, the background signal from elements in the conveyor itself grows accordingly. If not accommodated this would cause the analyzer to be inaccurate. The unique ABLC feature ensures that the system stays accurate no matter what loading conditions are encountered. 

Information Exchange and PC Interfaces

Integration of an online analyzer into a cement production line generally requires a communication interface with a plant control network. The CB Omni Fusion is extremely flexible in this regard and is compatible with most major communication protocols. The most popular protocol in use today is OPC. The system configures easily as either an OPC Server or an OPC Client.
