Area of Science:

  • Plasma physics
  • Optical engineering
  • Materials science

Background:

  • Infrared Imaging Video Bolometers (IRVB) are crucial for measuring 2D plasma radiation.
  • Current IRVB systems often use ultra-thin metal foils as radiation absorbers, which have inherent limitations.

Purpose of the Study:

  • To propose and validate a new radiation absorbing module for IRVB systems.
  • To overcome the shortcomings associated with conventional thin metal foils.

Main Methods:

  • Development of a novel module by depositing carbon and metal thin films on an infrared transmitting substrate.
  • Utilizing magnetron sputtering for thin film deposition.
  • Fabrication of a prototype and laboratory testing with a laser source.

Main Results:

  • The developed module, termed Deposited Layer on a Substrate, demonstrated feasibility as a radiation detector.
  • Experimental results validated the concept and performance of the new module.
  • The new module offers advantages over conventional foils used in IRVB.

Conclusions:

  • The Deposited Layer on a Substrate module presents a viable and improved alternative for plasma radiation detection in IRVB.
  • This patented technology effectively addresses the limitations of traditional foil absorbers.
  • Further research and application in IRVB systems are warranted.
