Inverse Compton Scattering (ICS) is a promising approach towards achieving high intensity, directional beams of quasi-monochromatic gammas, which could offer unique capabilities in research, medical and security applications. Practicality implementation of ICS sources, however, depends on the ability to achieve high peak brightness (~0.1-1.0 ICS photons per interacting electron), while increasi...

In the framework of chaotic scattering we analyze passive tracer transport in finite systems. In particular, we study models with open streamlines and a finite number of recirculation zones. In the nontrivial case with a small number of recirculation zones a description by means of asymptotic quantities (such as the eddy diffusivity) is not appropriate. The nonasymptotic properties of dispersio...

This technical note highlights the system requirements and operating conditions of automatic air recirculation valves and reviews compatibility of existing actuator types with these requirements. When comparing the available technologies, it becomes clear that air recirculation flap actuators containing a bipolar stepper motor offer key advantages over actuators with other motor types. It is sh...

Aquaculture has moving from conventional open systems to high density and highly productive land-based recirculation systems. Consumers increased consumption of fish and fish products due to recognition of their nutritional value along with social progress and the improvement of living standards. Traceability system is considered as an effective tool to guarantee safety in fish products and imp...

In order to improve centrifugal compressor performance predictive capability, an improved recirculation loss model in two-zone modeling system is presented in this paper. The new loss model correlates Reynolds number of the impeller with the recirculation loss. Performance prediction by the improved model is carried out on two turbochargers with different sizes based on COMPAL mode of the code ...

The CEBAF recirculator at Jefferson Lab includes two linear accelerators, each 200 meters in length. Due to varying betatron phase advance for different recirculation passes, misalignment, and other steering effects, orbit correction in the CEBAF linacs presents a complicated problem defying pass-by-pass solutions. Utilization of information from the beam position measurements at all recirculat...
