Comparison of Accelerator Codes for a RHIC Lattice
نویسنده
چکیده
We present the results of comparisons of performances of several tracking or/and analysis codes. The basic purpose of this program was to assess reliability and accuracy of these codes, Le. to determine the so-called "error bars" for the predicted values of tunes and other lattice functions as a minimum and, if possible, to discover potential difficulties with underlying physical models in these codes, inadequate algorithms, residual bugs and the like. Not only we have been able to determine the error bars, which for instance for the tunes at dp/p = +1% are Avx = 0.0027, Avy = 0. 0010, but also our program has brought about improvements of several codes.

Madx-ual Suite for Off-line Accelerator Design and Simulation*
We present here an accelerator modeling suite that integrates the capability of MAD-X and UAL packages, based on the Standard eXchange Format (SXF) interface. The resulting environment introduces a collection of accelerator applications ranging from the lattice design to complex beam dynamics studies. The extended capabilities of the MADX-UAL integrated approach have been tested and effectively...
متن کاملHeavy flavor in heavy-ion collisions at RHIC and RHIC II
In the initial years of operation, experiments at the Relativistic Heavy Ion Collider (RHIC) have identified a new form of matter formed in nuclei-nuclei collisions at energy densities more than 100 times that of a cold atomic nucleus. Measurements and comparison with relativistic hydrodynamic models indicate that the matter thermalizes in an unexpectedly short time, has an energy density at le...

متن کاملcritRHIC: The RHIC Low Energy Program
Recent experimental and theoretical developments have motivated interest in a more detailed exploration of heavy ion collisions in the range √ s NN =5–15 GeV. In contrast to interactions at the full RHIC energy of √ s NN =200 GeV, such collisions result in systems characterized by much higher baryon chemical potential, μB. Extensions of lattice QCD calculations to non-zero values of μB suggest ...
متن کاملUal-based Simulation Environment for Spallation Neutron Source Ring
The Unified Accelerator Libraries[1] are designed as a customizable and extendible environment for developing diverse accelerator applications. Its main architectural principle is a separation of physical entities and mathematical abstractions from algorithms. The accelerator algorithms are implemented as classes that share data via Common Accelerator Objects (Element, Bunch, Twiss, etc.). This...
