As linear accelerators were developed with higher beam currents, using magnetic fields to focus proton and heavy ion beams presented difficulties for the initial stages of the accelerator. Because the magnetic force is dependent on the particle velocity, it was desirable to create a type of accelerator which could simultaneously accelerate and ...
The linear induction accelerator was invented by Christofilos in the 1960s. [2] Linear induction accelerators are capable of accelerating very high beam currents (>1000 A) in a single short pulse. They have been used to generate X-rays for flash radiography (e.g. DARHT at LANL ), and have been considered as particle injectors for magnetic ...
The longest linac in the world is the Stanford Linear Accelerator, SLAC, which is 3 km (1.9 mi) long. SLAC was originally an electron–positron collider but is now a X-ray Free-electron laser. Linear high-energy accelerators use a linear array of plates (or drift tubes) to which an alternating high-energy field is applied.
The Compact Linear Accelerator for Research and Applications (CLARA) is a scientific user facility at Daresbury Laboratory. It is an electron linear accelerator (linac) currently under construction in the Electron Hall. CLARA is made up of three phases; Phase 1 is operational and has achieved energies of 50 MeV with bunch charges >250 pC. Phase ...
The main accelerator was an RF linear accelerator that accelerated electrons and positrons up to 50 GeV. At 3.2 km (2.0 mi) long, the accelerator was the longest linear accelerator in the world, and was claimed to be "the world's most straight object." [14] until 2017 when the European x-ray free electron laser opened.
In accelerator physics, a beamline refers to the trajectory of the beam of particles, including the overall construction of the path segment (guide tubes, diagnostic devices) along a specific path of an accelerator facility. This part is either the line in a linear accelerator along which a beam of particles travels, or
However, during the first months of operation, it became clear that an output energy of 500 MeV allowed for a more reliable running of the machine. [8] LIL consisted of so-called S band Linacs. These linear accelerators used a 35 MW pulsed klystron that drove microwave cavities at a frequency of 3 GHz, which accelerated the electrons and ...
Accelerator physics is a branch of applied physics, concerned with designing, building and operating particle accelerators. As such, it can be described as the study of motion, manipulation and observation of relativistic charged particle beams and their interaction with accelerator structures by electromagnetic fields .
