The success of Tevatron Run II is based on advances in accelerator physics, as well as on the excellence and advances in engineering, instrumentation and machine operation. We review the main advances in accelerator physics which contributed to the luminosity growth and/or improvement of the Tevatron complex operations, and discuss their applicability to future colliders.

The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory has now operated for a decade. Over this time the 2 physics programs at RHIC, based on heavy ion and polarized proton collisions respectively, have seen a substantial increase in performance and a variety of operating modes. The performance increases are presented with the dominant limiting effects, and upgrade plans...

The SuperB international team continues to optimize the design of an electron-positron collider, which will allow the enhanced study of the origins of flavor physics. The project combines the best features of a linear collider (high single-collision luminosity) and a storage-ring collider (high repetition rate), bringing together all accelerator physics aspects to make a very high luminosity...

Of the various advanced accelerator schemes that promise high accelerating gradients, optical-scale structures offer a distinct set of performance parameters along with their own challenges. In addition to the promise of an order of magnitude improvement in accelerating gradients (to ~GV/m) over conventional structures, these devices produce low charge, femto- to atto-second bunches at very...

The hollow electron beam collimator is a novel concept of controlled halo removal for intense high-energy beams in storage rings and colliders. It is based on the interaction of the circulating beam with a 5-keV, magnetically confined, pulsed hollow electron beam in a 2-m-long section of the ring. The electrons enclose the circulating beam, kicking halo particles transversely and leaving the...

A muon collider would be a powerful tool for exploring the energy-frontier with leptons, and would complement the studies now under way at the LHC. Such a device would offer several important benefits. Muons, like electrons, are point particles so the full center-of-mass energy is available for particle production. Moreover, on account of their higher mass, muons give rise to very little...

For a fixed size of a circular collider, its energy is limited by the strength of bending dipole magnets. Moreover, for both linear and circular machines, their maximum luminosity is determined (among other factors) by the strength of quadrupole magnets used for the final beam focusing. That is why there has been a permanent interest to higher-field and higher-field gradient accelerator...

Neutrino physics from muon decay is very much at the forefront of today's physics research. Large detectors installed in deep underground locations perform neutrino mass, CP violation, and oscillation studies using long- and short-baseline beams of neutrinos from muons decaying in flight.

A precision luminosity measurement is of critical importance for the ATLAS physics program, both for searches for new physics as well as for precision measurements of Standard Model cross-sections. The calibration of the luminosity is based on three so-called van der Meer scans that were performed in 2010. These scans determine the convolved beam sizes in the vertical and horizontal...

The dielectric laser acceleration (DLA) concept leverages well-established industrial fabrication capabilities and the commercial availability of tabletop lasers to reduce cost, while offering significantly higher accelerating gradients, and therefore a smaller footprint.

The plasma wakefield accelerator (PWFA) concept is experiencing renewed interest thanks to the recent experimental results that showed that ultrarelativistic electrons can gain as much as 42GeV in only 85cm of plasmas. In the PWFA a short particle bunch drives large amplitude wakefields in a neutral plasma. The wakefields can have a very large longitudinal component (>10GV/m) that leads to...
