MECHANICAL DESIGN AND INTEGRATION

VARIABLE RADIATION ATTENUATOR

The Cobalt 60 irradiator present in the CNA is used to irradiate electronic devices, but it does not offer control of the intensity of the emitted radiation. For this, a variable attenuator has been designed. This dimmer consists of an aluminum profile structure that supports two metal frames mounted on rails. Through these rails, one or another frame can be aligned on the outlet of the irradiator. These metal frames allow the installation of different thicknesses of lead sheets. In this way, two different levels of attenuation are available.
