What is the mass spectrometer of the accelerator?
The mass spectrometer of the accelerator is a laboratory device that uses a combination of magnetism and high voltage to measure radioactive elements. Although this was first demonstrated in the age of 30, the use of accelerators combined with weight spectrometry became common only in the 70s. Weight spectrometry is the measurement of the mass of the molecule or atom by separating various atoms of their weight or mass by means of magnetic fields.
Archeology, studying ancient civilizations, used the presence of radioactive materials, especially carbon, since the beginning of the 20th century. The scientist could take a sample from the archaeological site, measure the amount of radioactive carbon-14 present in the sample and estimate the age of the sample or artifact. Before using the mass spectrometer of the accelerator, the carbon-14 measurement was time-consuming and required a large amount of material. The science of using radioactive carbon to determine the age of ancient artifacts is called "carbon dating."
in the mass spectrometer of the acceleratorAtoror is several different sections, but the primary device is a magnetic separator and a tandem accelerator. The first part of the unit uses a low -power magnetic separator to remove unwanted particles or molecules from the sample current. Then the sample enters the tandem accelerator, which first accelerates the particles by attracting the negatively charged particles with a high -energy positive electric charge and over millions of volts.
accelerated particles then pass through an electron stripper, which is either a very thin layer of carbon or a specific gas. The electrons are removed from the particle, resulting in a positively charged ion. The ions are now accelerated again because they are repelled by a high positive accelerator charge. Therefore, this part of the device is called a tandem accelerator because you affect the ions twice by means of the effects of attraction and repellent caused by electric charge.
Once the high -speed ions leave the tandem part, the rest of the mass spectrometer is other magnets that can direct the sample current to the detector that calculates the number of particles that achieve it. Each part of the spectrometer is connected to computers that can adjust the electrical and magnetic power to control the product current. The detectors are very sensitive and can feel one radioactive ion in many millions of non -radioactive.
Along with its use in archeology and geology, a mass spectrometer of the accelerator can be used in medical diagnostic testing. The radioactive element, called the stopor, can be injected in a patient or included in small amounts in the drug taken by the patient. As the body absorbs the drug, the machine element can be seen using samples introduced into the mass spectrometer of the accelerator. The Spectrometer's ability on the See very small amounts of radioactive element makes the technique valuable because the patient sees a very low level of radioactivity, o owhich is assumed to cause health concerns.
