Mostly used with scanning tables to record data coded on 6 holes.
Cockcroft-Walton generator (or voltage doubler)(600kV) built by Philips and used in the Linac experimental area of the proton synclotron south hall (1964).Served as high voltage supply for the pre-injector of the 3Mev experimental Linac.
This focusing horn was developed in 1992 by Remo Maccaferri, Jean Claude Schnuriger and Lubrano di Scampamorte and is still operating in the AD complex at CERN (as of 2017). This device could pulse at 400 KA (160 KA for the previous version). This enabled an antiproton collection ten times better than the old one. Firstly, protons were accelerated to an energy of 26 GeV/c and ejected onto a metal target. From the spray of emerging particles, the magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, ten antiprotons were captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 - three hundred thousand million - antiprotons. Originally magnetic focusing horns were developed by Simon van der Meer - see for example object AC-022 in this database.
Sin títuloGargamelle was the name given to a big bubble chamber built at the Saclay Laboratory in France during the late 1960s. It was designed principally for the detection at CERN of the elusive particles called neutrinos.In 1973, André Lagarrigue and his colleagues found evidence for neutral currents in Gargamelle bubble chamber pictures. Gargamelle is on display at CERN in the Microcosm garden.
oldest CERN oscilloscope.
The 3.70 metre Big European Bubble Chamber (BEBC) was dismantled on 9 August 1984. One of the biggest detectors in the world, it produced direct visual recording of particle tracks. 6.3 million photos of interactions were taken with the chamber in the course of its existence.
<2> photomultiplier tubes. A device to convert light into an electric signal (the name is often abbreviated to PM). Photomultipliers are used in all detectors based on scintillating material (i.e. based on large numbers of fibres which produce scintillation light at the passage of a charged particle). A photomultiplier consists of 3 main parts: firstly, a photocathode where photons are converted into electrons by the photoelectric effect; secondly, a multiplier chain consisting of a serie of dynodes which multiply the number of electron; finally, an anode, which collects the resulting current.
