Harwell Synchrocyclotron
The Harwell Synchrocyclotron was a particle accelerator based at the Atomic Energy Research Establishment campus near Harwell, Oxfordshire. Construction of the accelerator began in 1946 and it was completed in 1949. The machine was of the synchrocyclotron design, with a 1.62T magnet of diameter 110" (2.8m) allowing protons to be accelerated to energies of 160-175MeV. Accelerator physicist John Adams, who later went on to lead design of CERN's SPS, was instrumental in the design and construction of this machine. Its main function was basic nuclear and particle physics research, with a focus on proton-proton and proton-neutron scattering. Comparisons were frequently drawn between the second cyclotron at the Harvard Cyclotron Laboratory and the Harwell Synchrocyclotron, and in 1974 clinicians from Oxford's Radcliffe Infirmary led by Dr T Hockaday floated plans to replicate the proton therapy work carried out at Massachusetts General Hospital with the accelerator.

Particle Accelerator
A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams. Large accelerators are used for fundamental research in particle physics. The largest accelerator currently active is the Large Hadron Collider (LHC) near Geneva, Switzerland, operated by the CERN. It is a collider accelerator, which can accelerate two beams of protons to an energy of 6.5 TeV and cause them to collide head-on, creating center-of-mass energies of 13 TeV. Other powerful accelerators are, RHIC at Brookhaven National Laboratory in New York and, formerly, the Tevatron at Fermilab, Batavia, Illinois. Accelerators are also used as synchrotron light sources for the study of condensed matter physics. Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncological purposes, radioisotope production for medical diagnostics, ion ...

Radcliffe Infirmary
The Radcliffe Infirmary was a hospital in central north Oxford, England, located at the southern end of Woodstock Road on the western side, backing onto Walton Street. History The initial proposals to build a hospital in Oxford were put forward at a meeting of the Radcliffe Trustees, who were administering John Radcliffe's estate valued at £4,000, in 1758. The facility was constructed on land given by Thomas Rowney, one of the two members of parliament for Oxford. The foundation stone was laid on 27 August 1761 and the new facility was officially opened on 18 October 1770. A fountain of the Greek god Triton was placed in front of the main infirmary building in 1858 and the Oxford Eye Hospital was established on the site in 1886.A brief history of the Nuffield Laboratory of Ophthalmology ...

Buildings And Structures In Oxfordshire
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZETA (fusion Reactor)
ZETA, short for Zero Energy Thermonuclear Assembly, was a major experiment in the early history of fusion power research. Based on the Z-pinch, pinch Plasma (physics), plasma confinement technique, and built at the Atomic Energy Research Establishment in the United Kingdom, ZETA was larger and more powerful than any fusion machine in the world at that time. Its goal was to produce large numbers of fusion reactions, although it was not large enough to produce net energy. ZETA went into operation in August 1957 and by the end of the month it was giving off bursts of about a million neutrons per pulse. Measurements suggested the fuel was reaching between 1 and 5 million kelvins, a temperature that would produce nuclear fusion reactions, explaining the quantities of neutrons being seen. Early results were leaked to the press in September 1957, and the following January an extensive review was released. Front-page articles in newspapers around the world announced it as a breakthro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

St Bartholomew's Hospital
St Bartholomew's Hospital, commonly known as Barts, is a teaching hospital located in the City of London. It was founded in 1123 and is currently run by Barts Health NHS Trust. History Early history Barts was founded in 1123 by Rahere (died 1144, and entombed in the nearby Priory Church of St Bartholomew the Great), a favourite courtier of King Henry I. The dissolution of the monasteries did not affect the running of Barts as a hospital, but left it in a precarious position by removing its income. It was refounded by King Henry VIII in December 1546, on the signing of an agreement granting the hospital to the Corporation of London.''St Bartholomew's Hospital'' ''Old and New London'': Volume 2 (1878), pp. 359–363.

Imaging Phantom
Imaging phantom, or simply phantom, is a specially designed object that is scanned or imaged in the field of medical imaging to evaluate, analyze, and tune the performance of various imaging devices. A phantom is more readily available and provides more consistent results than the use of a living subject or cadaver, and likewise avoids subjecting a living subject to direct risk. Phantoms were originally employed for use in 2D x-ray based imaging techniques such as radiography or fluoroscopy, though more recently phantoms with desired imaging characteristics have been developed for 3D techniques such as SPECT, MRI, CT, Ultrasound, PET, and other imaging methods or modalities. Design A phantom used to evaluate an imaging device should respond in a similar manner to how human tissues and organs would act in that specific imaging modality. For instance, phantoms made for 2D radiography may hold various quantities of x-ray contrast agents with similar x-ray absorbing properties to n ...

Proton Therapy
In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer. The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy nearby tissues. When evaluating whether to treat a tumor with photon or proton therapy, physicians may choose proton therapy if it is important to deliver a higher radiation dose to targeted tissues while significantly decreasing radiation to nearby organs at risk. The American Society for Radiation Oncology Model Policy for Proton Beam therapy says proton therapy is considered reasonable if sparing the surrounding normal tissue "cannot be adequately achieved with photon-based radiotherapy" and can benefit the patient. Like photon radiation therapy, proton therapy is often used in conjuncti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford
Oxford () is a city in England. It is the county town and only city of Oxfordshire. In 2020, its population was estimated at 151,584. It is north-west of London, south-east of Birmingham and north-east of Bristol. The city is home to the University of Oxford, the oldest university in the English-speaking world; it has buildings in every style of English architecture since late Anglo-Saxon. Oxford's industries include motor manufacturing, education, publishing, information technology and science. History The history of Oxford in England dates back to its original settlement in the Saxon period. Originally of strategic significance due to its controlling location on the upper reaches of the River Thames at its junction with the River Cherwell, the town grew in national importance during the early Norman period, and in the late 12th century became home to the fledgling University of Oxford. The city was besieged during The Anarchy in 1142. The university rose to dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
