Measured in Kilovolts. ...An optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light's intensity but could also, for instance, be the polarization state.

... This X-ray tube was designed to provide electrostatic protection for the filament (cathode) so as to permit long life to be achieved at operating voltages in the range 100-300kV. ...The Ed Muirhead Physics Museum Level 2, The School of Physics, David Caro Building (192) Corner of Elgin and Swanston Streets The University of Melbourne Parkville melbourne This X-ray tube was designed to provide electrostatic protection for the filament (cathode) so as to permit long life to be achieved at operating voltages in the range 100-300kV. ...This X-ray tube was designed to provide electrostatic protection for the filament (cathode) so as to permit long life to be achieved at operating voltages in the range 100-300kV. It is not certain whether the tube was in use within the School by Professor Laby’s X-ray group or whether it was presented to the School by a medical user. It would be somewhat surprising if it fitted into this School of Physics Research Program at a date as late as 1933 when tubes with demountable anodes were in use.Glass bulbous X-ray tube attached at either end to metal electrodes. Mounted for demonstration on a wooden base. Dated1937On glass bulb: “Machlett Patent 1954016” -

The whole is housed within an electrostatic shield (Faraday cage) - a beehive shaped wire cage enclosure (aka a “bird cage”). The quadrants and cage stand on a round base platform on three legs with levelling screws (tribach base?). Arising from the platform is a separate vertical rod arises from the periphery and terminates over the axis of cylindrical symmetry and from which provision is made for a conducting suspension fibre which supports the horizontal “paddle” which is free to rotate within the cylindrical cavity of the four quadrants. The suspension and paddle are unfortunately missing.Label on front: “Natural Philosophy Laboratory No. University of Melbourne” Engraved on front: “Elliott Bros London” -

... The small mushroom antenna could detect short-range (20-mile) changes in electrostatic field associated with lightning strikes. ...The small mushroom antenna could detect short-range (20-mile) changes in electrostatic field associated with lightning strikes. ...Lightning is one of the major causes of bushfires, particularly in the remote mountains. This lightning detector system was developed by Dr. Peter Kourtz at Canada’s forest fire research institute. By 1977, some 300 were in use across the country. The small mushroom antenna could detect short-range (20-mile) changes in electrostatic field associated with lightning strikes. It needed to be placed out in the open on a hilltop and away from nearby trees. It simply counted the number of "strikes". The detector doesn't seem to have a direction finding capability or be able to distinguish between cloud-to-cloud or cloud-to-ground lightning. It's not sure how this particular unit found its way to Victoria. The Bureau of Meteorology's (BOM) current lightning detector network uses radio waves emitted by lightning to pinpoint the location of lightning strikes. The network is operated by a private company that sends data to the BOM in real time. Lightning detection systems use sensors like antennas, GPS receivers, and processing systems to detect radio waves, also known as sferics. The systems calculate the lightning's location and speed by measuring how long it takes for the radio signal to reach the different antenna stations. The BOM also has a Thunderstorm Tracker that uses weather radar data to identify areas of potential thunderstorm activity. The tracker updates every six minutes and shows the direction thunderstorms are moving, as well as their expected position in 10, 20, and 30 minutesLightning detector 1970sQ-Techforests commission victoria (fcv), weather, bushfire, bushfire aviation -
