Experimental plan of COMPASS
نویسنده
چکیده
COMPASS is a new fixed target experiment at CERN to study the nucleon spin structure with a polarized muon beam and a polarized nucleon target. Gluon spin contribution to the nucleon spin will be studied by measuring the asymmetry of open charm production or high PT hadron pair production in semi-inclusive deep inelastic scattering of a polarized muons on a polarized nucleon target. The COMPASS spectrometer is a two-stage spectrometer equipped with ring image Cherenkov counters and calorimeters. The run will start to take data in 2001.

Optimization of Magnetic Perturbation Spectra for the COMPASS Tokamak
The COMPASS tokamak, recently transferred from UKAEA Culham to IPP Prague, is equipped with a set of saddle coils for producing controlled resonant magnetic perturbations (RMPs). In the future experimental programme of COMPASS we plan to focus on studies of RMPs, especially in view of their application as an ELM control mechanism and their planned use in ITER. In the present contribution we des...
متن کاملQuantitative evaluation of 3D dosimetry for stereotactic volumetric‐modulated arc delivery using COMPASS
The purpose of this study was to evaluate quantitatively the patient-specific 3D dosimetry tool COMPASS with 2D array MatriXX detector for stereotactic volumetric-modulated arc delivery. Twenty-five patients CT images and RT structures from different sites (brain, head & neck, thorax, abdomen, and spine) were taken from CyberKnife Multiplan planning system for this study. All these patients...
متن کاملMagnetic Calibration of Three-Axis Strapdown Magnetometers for Applications in Mems Attitude-Heading Reference Systems
In a strapdown magnetic compass, heading angle is estimated using the Earth's magnetic field measured by Three-Axis Magnetometers (TAM). However, due to several inevitable errors in the magnetic system, such as sensitivity errors, non-orthogonal and misalignment errors, hard iron and soft iron errors, measurement noises and local magnetic fields, there are large error between the magnetometers'...

Quality Compass, a collaborative effort between private and public purchasers and the managed care industry directed by the National Committee for Quality Assurance (NCQA), has succeeded in laying the foundation for a national quality reporting system based on performance data obtained from the Health Plan Employer Data and Information Set (HEDIS) and the Member Satisfaction Survey (MSS). Howev...
متن کاملIntelligent control and decision-making demonstrated on a simple compass-guided robot
This paper presents the architecture and algorithms developed for Dom Dinis, a simple compass-guided robot built by the authors. This includes environment exploration, task planning and task execution. Environment exploration, based on repeating a reactive goal search, enables a progressive construction of a grid-based map. Based on the (possibly incomplete) map, the robot is able to plan its t...
