چکیده

The test of the crab waist collision scheme, undergoing at the ee Frascati DAΦNE accelerator complex since February 2008, requires a fast and accurate measurement of the absolute luminosity, as well as a full characterization of the background conditions. Three different monitors, a Bhabha calorimeter, a Bhabha GEM tracker and a gamma bremsstrahlung proportional counter have been designed, tested and installed around the interaction point end of 2007-beginning of 2008. In this paper, we describe these detectors and present their performances in various operation conditions during the 2008 and 2009 DAΦNE runs.

Crab Waist Collisions in Daφne and Super-b Design

The new idea of increasing the luminosity of a collider with crab waist collisions and first experimental results from the DAΦNE Φ-Factory at LNF, Frascati, using this concept are presented. Consequences for the design of future factories will be discussed. An outlook to the performance reach with crab waist collisions is given, with emphasis on future B Factories. INTRODUCTION A novel collisio...

Experience with Da!ne Upgrade including Crab Waist

In 2007 DA!NE was upgraded to operate in a regime of large Piwinski angle, with a novel interaction region optics, reduced vertical beta at the interaction point, and additional sextupoles providing for Crab-Waist collisions. The specific luminosity has been boosted by more than a factor of four at low currents, and the present peak luminosity is by about a factor of 3 higher than the maximum v...

Local Chromatic Correction Scheme and Crab-waist Collisions for an Ultra-low Beta* at the Lhc∗

We discuss potential merits and the parameter range of interest for a possible crab-waist collision scheme at the LHC, and report preliminary optics studies of a local chromatic correction scheme with flat beams (β∗ x β∗ y ), which could boost the LHC luminosity by about an order of magnitude and would also allow for crab-waist collisions.

Da Ne Setup and Operation with the Crab-waist Collision Scheme

In the second half of 2007 a major upgrade has been implemented on the Frascati DA NE collider in order to test the novel idea of Crab-Waist collisions. New vacuum chambers and permanent quadrupole magnets have been designed, built and installed to realize the new configuration. At the same time the performances of relevant hardware components, such as fast injection kickers and shielded bellow...

TOUSCHEK BACKGROUND AND LIFETIME STUDIES FOR THE SuperB FACTORY

The novel crab waist collision scheme under test at the DAΦNE Frascati Φ-factory finds its natural application to the SuperB project, the asymmetric ee flavour factory at very high luminosity with relatively low beam currents and reduced backgrounds. The SuperB accelerator design requires a careful choice of beam parameters to reach a good trade-off between different effects. We present here si...
