Colliding Nanobeams in CLIC with Magnets Stabilized to the Sub-nm Level

چکیده
The Compact LInear Collider (CLIC) aims at colliding ee beams at 1.5 TeV with effective transverse spot sizes of 60 nm (horizontal) times 0.7 nm (vertical). Strict stability tolerances must be respected in order to achieve a sufficient overlap of the two colliding beams. A stability test stand has been set up at CERN, bringing latest stabilization technology to the accelerator field. Using this technology, a CLIC prototype magnet was stabilized in a normal CERN working environment to less than 1-nm vertical RMS motion above 4 Hz. Detailed simulations of the timedependent luminosity performance of CLIC are discussed. They include the beam-beam interaction, the beam-based feedbacks and the measured data on magnet stability.

In-situ Vibration Measurements of the Ctf2 Quadrupoles
The Compact LInear Collider (CLIC), presently under study at the European Organization for Nuclear Research (CERN), aims at colliding high-energy “nanobeams” at a luminosity of 10 cm−2s−1. Vibrations of the lattice elements, if not properly corrected, can result in a loss in performance by creating both unacceptable emittance growth in the linear accelerator and relative beam-beam offsets at th...

The palladium metal is the most frequently used metal because of its excellent catalytic efficiency and most flexible varying oxidation state. So, we report that palladium nanoparticles (Pd NPs) stabilized by a ligand (o-vanilindiphenylethanedionedihydrazone, L) using reverse micelles method have been synthesized, while all particles are in spherical shape and ranging between 10 and...

In the Compact Linear Collider (CLIC) project high luminosity will be achieved by generating and preserving ultra low beam emittances. It will require a mechanical stability of the quadrupole magnets down to the level of 1 nmrms for frequencies above 1 Hz throughout the 24 km of linac structures. Studies are presently being undertaken to stabilize each quadrupole by means of an active feedback ...
