Some physics experiments with 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" (...

The Replication of Hertz:s Cathode Ray Experiments

I reappraise in detail Hertz's cathode ray experiments. I show that, contrary to Buchwald's (1995) evaluation, the core experiment establishing the electrostatic properties of the rays was successfully replicated by Perrin (probably) and Thomson (certainly). Buchwald's discussion of &current puri"cation' is shown to be a red herring. My investigation of the origin of Buchwald's misinterpretatio...

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...

Design and Simulation of Hot Cathode Ionization Vacuum Gauge with no X-Ray Limitations

In this paper, the MEMS type ionization gauge with no X-Ray limitations has been presented. Having the dimensions of 2.4 mm× 0.8mm × 1.4 mm, the designed gauge is 9000 times smaller than the conventional type and can operate in HV and UHV pressures up to 5×10-9 torr. Operating at the temperature of 750°C, the cathode of proposed gauge is implemented using nickel and works in a way in...
