Design
The technology of superconducting accelerating cavities has a fundamental accelerating gradient limit of ~60 MV/m. Room temperature cavities, though less power-efficient, provide the possibility to generate higher RF gradients and hence allow a shorter accelerator length for the same collision energy. Since no conventional RF source can provide the necessary power for CLIC beam acceleration at a frequency of 12 GHz, a two-beam acceleration scheme has been designed. The high-current low-energy drive beam serves as an RF power source for the low-current high-energy main beam, making the whole machine a large power transformer. The main beams are brought into collision in the middle of the accelerator, where the detector is installed.
Total power consumption is estimated to be 415 MW for the 3 TeV version of CLIC.

Famous quotes containing the word design:
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
