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 ¤t puri"cation' is shown to be a red herring. My investigation of the origin of Buchwald's misinterpretatio...
متن کاملDesign 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...
متن کاملThe 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" (...
متن کاملX-ray Emission Accompanying Cathode Microdischarge
Electrical discharge in vacuum is accompanied by X-ray radiation. Knowledge of the generation mechanism of radiation may lead to its practical use. The analysis of this phenomenon indicates that it is only at the discharge development phase until the moment of the anode plasma generation that the proper conditions for X-ray generation are satisfied. The intensity of radiation is dependent on th...
متن کاملA multi-channel cathode-ray phonocardiograph.
The difficulties of recording the faint murmurs of early rheumatic valvulitis are well known, and for this reason it was considered advisable to develop a cathode-ray phonocardiograph. This is theoretically the ideal recording device owing to its minimal inertia and high sensitivity. This phonocardiograph is intended to provide objective confirmation of clinical findings on auscultation, record...
