Exempel på hur man kan använda LINAC i en mening

• Medical physics of radiation therapy can involve work such as dosimetry, linac quality assurance, and brachytherapy.
• A linear particle accelerator (often shortened to linac) is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline.
• Large synchrotrons usually have a linear accelerator (linac) to give the particles an initial acceleration, and a lower energy synchrotron which is sometimes called a booster to increase the energy of the particles before they are injected into the high energy synchrotron ring.
• The main part then is operated by a classical linac of the Alvarez type which resonates at 108 MHz.
• Japan Proton Accelerator Research Complex (J-PARC): A proton accelerator complex consisting primarily of a 600 MeV linac, a 3 GeV synchrotron and 50 GeV synchrotron.
• This, paired with plasma-wakefield acceleration methods under development and linear accelerator (linac) technology, could pave the way to next-generation, compact (and hence cheaper), less prone to RF breakdown (current limits for surface E fields are of the order of 10s-100 MV/m), high energy output linacs.
• Some components of this linear accelerator are still operating as part of the ISIS Neutron and Muon Source injector linac over 50 years after their first use.
• Microtrons provide high-energy electron beams with a low beam emittance (no radiation equilibrium) and a high repetition rate (equal to the operation frequency of the linac).
• In the low energy beam transport, right after the ion source, magnetic solenoids are used, in the DTL permanent quadrupole magnets are used and the rest of the linac uses electromagnetic quadrupoles.
• Modern tomotherapy and conventional linac systems incorporate one or both of megavoltage X-ray or kilovoltage X-ray imaging systems, enabling image-guided radiation therapy (IGRT).
• Annually it performed about 150-200 kidney transplantations, 3500-4000 stentings for coronaries diseases, 3000 laparoscopies for GI diseases, 1500 Radiotherapy patients (linac Eleckta) for cancers, Pediatric Radiation (1st in Vietnam), stem cells for breast and ovary cancers, NOTES and TaTME for colorectal cancers, ERCP-SE, ESD-EMR for GI early cancers; 3D, 4K laparoscopic surgery systems; IVF (In Vitro Fertilization) 200-300 cases per year,.
• 1 MeV to more than 600 MeV are produced in Target 4 (an unmoderated tungsten spallation source) using the 800-MeV proton beam from the LANSCE linac.
• Lattices can be closed (cyclic accelerators like the synchrotrons), linear (for linac facilities) and are also used at interconnects between different accelerator structures (transfer beamlines).
• The equally elegant experimental application of this theory was described in an article by Hayward, Barber, and Sazama in which “a beam of plane-polarized monochromatic photons” from a carbon target in a linac bremsstrahlung beam was “produced by the resonance fluorescence of the well-known 1+ state at 15.
