Study on MgO cathode Applied to Cathode-Ray Tube

The Channel Multiplier Cathode-ray Tube

This paper describes a new approach to cathode-ray tube design aimed at achieving a significant depth reduction. The addressing function of the electron beam has been separated from the light generation process by a channel electron multiplier array, allowing the use of a novel deflection system based on a low-power scanning beam. Monochrome versions of the thin tube have been made with a 12" (...

Luminance artifacts of cathode-ray tube displays for vision research.

Phosphor persistence, video bandwidth, DC restoration and high-voltage regulation affect the appearance of images presented on cathode-ray tubes (CRTs), potentially resulting in differences between nominal and actual stimuli. We illustrate these effects by measuring physical parameters of horizontal and vertical static and counter-phase flickering gratings, and we illustrate problems for vision...

Study of Writing Methodologies for Graphical Display on Flat Cathode Ray Tube

This paper describes various display devices which are useful for avionics applications. It focuses the attention of cathode ray tube based displays which has distinct advantages in terms of better luminance, contrast ration and the mature level of technology. Various writing methods have been studied which are chosen depending on application, contrast level required and on the amount of inform...

Cathode Ray Tube (crt) Lead Glass: Lead Leaching Study after a Chelating Agent Treatment

This study is focused on the removal of leachable lead present in CRT (cathode ray tube) glass employing different chelating agents, NTA (nitrilotriacetic acid) and ATMP (amino trimetilen phosphonic acid), and then on the evaluation of their extractive capability. The operating conditions are the following: T=80°C, t=1h, pH=10, solid/liquid weight ratio=1/10, reagent concentration= 0.1 M. After...
