What are synonyms for crystal detector? Language; Watch; Edit; Active discussions. Early point contact diodes were made from a galena crystal (lead sulfide) and a metallic pin known as a "cat's whisker". Thus, point contact diode got a descriptive name as a cat whisker detector. Crystal detector definition, a device for rectifying a modulated radio-frequency signal, consisting of a crystal of germanium, silicon, galena, or the like with a cat whisker contact, permitting a high-frequency current to pass freely in one direction only: one of the two principal components of a crystal … Meaning of crystal detector. Summary [ edit | edit source ] The Crystal Detector is a unique device that allows BUD to find Crystals much easier. A radiation detector comprising a scintillation crystal, means to convert optical radiation into electrical charge carriers and detector means to detect the generated charge carriers characterised in that a gap (19) provided with means (17) to inhibit the passage of charge carriers is positioned between said crystal (1) and said detector means (9). It was designed to detect neutral particles and was used to discover the ηc meson.Its central section was a spark chamber surrounded by a nearly-complete sphere of scintillating crystals (), for which it was named. This is a direct descendant of the old crystal detector of the ‘crystal and cat’s-whisker’ era, and is shown in Fig. Other articles where Crystal detector is discussed: Greenleaf Whittier Pickard: electrical engineer who invented the crystal detector (one of the first devices widely used for receiving radio broadcasts) and who was also one of the first scientists to demonstrate … Talk:Crystal detector. Features – The instrument converts RF power levels applied to the 50 W input connector into proportional values of DC voltage. The Crystal Ball is a hermetic particle detector used initially with the SPEAR particle accelerator at the Stanford Linear Accelerator Center beginning in 1979. This project is to perform material purification and crystal growth underground for next generation, ultra-low background experiments at the Sanford Underground Laboratory at Homestake and DUSEL.

Crystal Detector Galène Carter Manufacturing Co., The; East Cleveland OH, build 1925, 11 images, Etats-Unis, schémas, lampes, semi-conducteurs, Poste à A crystal detector is an obsolete electronic component in some early 20th century radio receivers that used a piece of crystalline mineral as a detector (demodulator) to rectify the alternating current radio signal to extract the audio modulation which produced the sound in the earphones. The capacitors C1 and C2 works as a capacitive voltage divider that is connected to the transistor T1. What does crystal detector mean? The transistor T1 and the crystal to be tested together makes a complete crystal oscillator. Commercial crystal testers are however very expensive, that is why this simple electronic crystal tester was born.

Définitions de crystal detector, synonymes, antonymes, dérivés de crystal detector, dictionnaire analogique de crystal detector (anglais) A crystal detector is an obsolete electronic component in some early 20th century radio receivers that used a piece of crystalline mineral as a detector (demodulator) to rectify the alternating current radio signal to extract the audio modulation which produced the sound in the earphones. It has a suction cup gun to hold on to Green Crystal Storage Boxes and an opening storage in the rear. Ce dernier comprend une première face de cristal qui vient en contact avec la solution et une deuxième face de cristal isolée du contact avec la solution. The crystal surfaces that are not in contact with the PMT are covered with an aluminum coating (about 0.05 cm thick), which blocks out external light and protects the scintillation crystal detector from atmospheric moisture (particularly hygroscopic crystal detectors) and from physical damage. Information and translations of crystal detector in the most comprehensive dictionary definitions resource on the web. I’d like to know what a piezoelectric sorption detector is. crystal detector (n = noun.artifact) - a detector consisting of a fine wire in contact with a galena crystal; acts as a rectifier; has parts: crystal is a kind of detector Antonyms for crystal detector. It has 101 parts and a Hydronaut. I modern crystal radios we use a diode as the "detector". Noun crystal detector has 1 sense. Crystal Growth and Detector Development . In most cases, the "crystal" is a piece of galena (lead sulfide), though other minerals were used as well, including silicon, pyrite ("fool's gold"), and a number of others. If the crystal being tested is intact, the circuit oscillates. Really not tougher to build, but items are harder to find to make the detector. The Crystal Detector is a tool used by the main character of Grow Up, BUD. Remarques: Wireless Corporation Horizontal Crystal Detector. A crystal detector is an obsolete [1] electronic component in some early 20th century radio receivers that used a piece of crystalline mineral as a detector (demodulator) to rectify the alternating current radio signal to extract the audio modulation which produced the sound in the earphones. Mostly the germanium is housed in a small glass housing with wire leads coming off each end. Explanation of crystal detector Explanation of crystal detector Information about crystal detector in … 6150 Crystal Detector is a medium-sized Hydronauts set. A crystal radio is the original example of a true detector; here a crude point-contact diode was used to rectify a AM modulated signal back to baseband so the listener could take the A-train to Harlem with Count Basie over headphones if the room was quiet enough. Single photons can be detected by several types of detectors without nonlinear crystals, E.g., specially designed photomultipliers produce 100 mV pulse from one photon absorbed by photocathode. Crystal surface makes contact with the fine metallic probe. traduction crystal detector dans le dictionnaire Anglais - Francais de Reverso, voir aussi 'crystal ball',liquid crystal',liquid crystal display',liquid crystal display', conjugaison, expressions idiomatiques 2 words related to crystal detector: crystal, detector. A thermoluminescent dosimeter, abbreviated as TLD, is a passive radiation dosimeter, that measures ionizing radiation exposure by measuring the intensity of visible light emitted from a sensitive crystal in the detector when the crystal is heated.The intensity of light emitted is measure by TLD reader and it is dependent upon the radiation exposure. 1 Description 2 Background 3 Notes 4 Gallery 5 Minifigures Included 6 External links The Crystal Detector is one of the larger Hydronauts sets.
