In 1897, physicist J.J. Thomson performed a cathode-ray tube experiment, which led to the discovery of electrons.

IF a fine beam of homogeneous cathode rays is sent nearly normally through a thin celluloid film (of the order 3 × 106 cm. thick) and then received on a photographic plate 10 cm. away and ...

India has discovered rare earth elements like Scandium and Strontium in coal mine waste at Telangana’s open-cast mines. The government is now expanding exploration to other mining and petroleum ...

The goal of this research is to develop an instant turn-on X-ray tube with high speed response. The tube is expected to produce a micro-spot less than 0.5mm at a voltage of 40kV and a current of 1mA.

The cathode ray oscillograph, since its invention by Braun, has developed along three lines. The major types of tubes are the high voltage tubes with a fluorescent screen, the high voltage tubes with ...

India’s copper cathode imports declined 34 per cent year-on-year in 2024-25 (FY25), largely due to a three-month supply disruption triggered by a quality control order (QCO), even as imports of ...
