"We estimate that as a result of putting state-of-the-art LINACs into areas that have not previously had one, in future 1200 people each year will be able to access radiation treatment locally rather than travelling long distances.
The roughly 90-meter-long (295 feet) Linac 4 will be more than thrice as strong as the currently used Linac 2, which accelerates protons to energies of about 50 megaelectronvolts (MeV).
The results showed not only that the filters flattened the beam as a function of the design of the flattening filter but also that they were also able to differentiate the fluence spectrum depending on the energy at which the LINAC operated.
The remainder of the funding for the Linac machine came through donations given to the North Wales Cancer Treatment Centre through the North Wales NHS Charity, Awyr Las.
Elekta is working on the next generation of the linac, which will combine a magnetic resonance imaging (MRI) device with a linac.
She said the LINAC uses microwave technology similar to that used for radar to accelerate electrons in a part of the accelerator called the "wave guide." The electrons collide with a heavy metal target producing high-energy X-rays that are shaped as they exit the machine to conform to the shape of the patient's tumor.
Velindre Cancer Centre now has seven linear accelerators, also known as linacs.
After SLAC's linac accelerates very short pulses of electrons to 99.9999999 percent the speed of light, the LCLS takes them through a 100-meter stretch of alternating magnets that force the electrons to slalom back and forth.
Julie Hall, who leads the BSc Radiotherapy course at Birmingham City University, said: "The system works by using an actual radiotherapy handset in combination with 3D technology which recreates the radiotherapy machine (known as a linear accelerator or 'linac'), the room in which it is situated and the patient lying on the couch.
This information is then transmitted to the computer-controlled, six-axis KUKA KR 210 robot to initialize the pointing of the linac beam.
The move follows the award of $18 M to Cornell earlier this year from the National Science Foundation to start development of the energy-recovery LINAC. e2v klystrons, chosen on the basis of their high signal gain and high output power, will provide the microwave energy used to accelerate the beam in the injector stage of the test ERL.
When completed, LENS will consist of a 13 MeV proton linac capable of producing a time-average current of 2.5 mA.
