Performance Characterization of A New Cam System
نویسندگان
چکیده
Continuous Air Monitors (CAMs) are used in nuclear facilities to detect airborne alpha-emitting transuranic radionuclides in work areas, stacks and ducts. We have now tested the first commercial version of the original Los Alamos/Texas A&M design for its performance. The penetration of inhalable-size particles onto the CAM filter is better than 80%, with excellent uniformity of sample. With the patented diffusion screen in place, the reduction of freshly formed radon decay products is 99%. With or without the diffusion screen in place, the new background compensation algorithm shows reliable detection and alarm capabilities in environments with freshly formed as well as aged radon progeny.

متن کاملDynamic and Stability Analysis of Flexible Cam-Follower Systems
In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients. Floquet theory is employed to s...
