N* physics and nonperturbative quantum chromodynamics : proceedings of the joint ECT*/JLAB workshop, Trento, Italy, May 18-29, 1998 by S Simula( Book )
2 editions published in 1999 in English and held by 90 WorldCat member libraries worldwide
The workshop was devoted to a summary of recent experimental and theoretical research on N* physics. Special emphasis was given to the information that photo- and electro-production of nucleon resonances can provide on the non-perturbative regime of quantum chromodynamics. Discussions among experimentalists and theoreticians were stimulated in order to pursue the interpretation of the huge amount of forthcoming data from several laboratories in the world. This volume contains both the invited lectures and the contributions. On the main topics, like single and double pion production, pi- and K-meson production, the GDH sum rule, and the spin of the proton

Undulator interruption in high-gain free electron lasers ( )
7 editions published between 1996 and 1997 in English and held by 22 WorldCat member libraries worldwide
The paper discusses some of the assumptions and methods employed for the control of ionizing radiation in the specifications for the civil construction of a planned free electron laser facility based on a 200 MeV, 5 mA superconducting recirculation electron accelerator. Consideration is given firstly to the way in which the underlying building configuration and siting aspects were optimized on the basis of the early assumptions of beam loss and radiation goals. The various design requirements for radiation protection are then considered, and how they were folded into an aesthetically pleasing and functional building
Control system reliability at Jefferson Lab ( )
4 editions published in 1997 in English and held by 16 WorldCat member libraries worldwide
In this paper the current plans for the control system for Thomas Jefferson National Accelerator Facility's (Jefferson Lab's) Infrared Free Electron Laser (FEL) are presented. The goals for the FEL control system are fourfold: (1) to use EPICS and EPICS compatible tools, (2) to use VME and Industry Pack (IPs) interfaces for FEL specific devices such as controls and diagnostics for the drive laser, high power optics, photocathode gun and electron-beam diagnostics, (3) to migrate Continuous Electron Beam Accelerator Facility (CEBAF) technologies to VME when possible, and (4) to use CAMAC solutions for systems that duplicate CEBAF technologies such as RF linacs and DC magnets. This paper will describe the software developed for FEL specific devices and provide an overview of the FEL control system
Transverse Quark Spin Effects and the Flavor Dependence of the Boer-Mulders Function ( )
3 editions published in 2007 in English and held by 12 WorldCat member libraries worldwide
There is a measure of debate within the nuclear community concerning the relevance of quark degrees of freedom in understanding nuclear structure. We briefly outline some of the key issues and review the impressive progress made recently within the framework of the quark-meson coupling model. In particular, we explain in quite general terms how the modification of the internal structure of hadrons in-medium leads naturally to three- and four-body forces, or equivalently to density dependent effective interactions
Fabrication and Testing of the SRF cavities for the CEBAF 12 GeV Upgrade Prototype Cryomodule Renascence ( )
2 editions published in 2005 in English and held by 10 WorldCat member libraries worldwide
Twelve seven-cell niobium cavities for the CEBAF 12 GeV upgrade prototype cryomodule Renascence have been fabricated at JLab and tested individually. This set includes four of the ''Low Loss'' (LL) design and eight of the ''High Gradient'' (HG) design. The fabrication strategy was an efficient mix of batch job-shop component machining and in-house EBW, chemistry, and final-step machining to meet mechanical tolerances. Process highlights will be presented. The cavities have been tested at 2.07 K, the intended CEBAF operating temperature. Performance exceeded the tentative design requirement of 19.2 MV/m CW with less than 29 W dynamic heat dissipation. These results, as well as the HOM damping performance are presented

The GlueX experiment and lattice QCD ( )
4 editions published in 2006 in English and held by 10 WorldCat member libraries worldwide
Hadronic form factors are objects that contribute significantly to our understanding of the structure of matter. The simplest hadronic system is the pion, whose electromagnetic structure is given by a single form factor (F). In this talk the results from the most recent Fpi at Jefferson Lab are presented
Effective Field Theory and Isospin Violation in Few-Nucleon Systems ( )
2 editions published in 2004 in English and held by 10 WorldCat member libraries worldwide
I discuss the leading and subleading isospin--breaking three--nucleon forces in the chiral effective field theory framework. I have discussed the leading and subleading isospin-violating 3NFs. The leading contributions are generated by one- and two-pion exchange diagrams with their strength given by the strong neutron-proton mass difference. The subleading corrections are again given by one- and two-pion exchange diagrams, driven largely by the charged-to-neutral pion mass difference and also by the electromagnetic neutron-proton mass difference and the dimension two electromagnetic LEC f₁. In the future, these isospin-breaking forces should be used to analyze few-nucleon systems based on chiral EFT
Measuring & Matching Transport Optics at Jefferson Lab ( )
2 editions published in 2003 in English and held by 10 WorldCat member libraries worldwide
A fully integrated Machine Protection System (MPS) is critical to efficient commissioning and safe operation of all high current accelerators. The Jefferson Lab FEL [1,2] has multiple electron beam paths and many different types of diagnostic insertion devices. The MPS [3] needs to monitor both the status of these devices and the magnet settings which define the beam path. The matrix of these devices and beam paths are programmed into gate arrays, the output of the matrix is an allowable maximum average power limit. This power limit is enforced by the drive laser for the photocathode gun. The Beam Loss Monitors (BLMs), RF status, and laser safety system status are also inputs to the control matrix. There are 8 Machine Modes (electron path) and 8 Beam Modes (average power limits) that define the safe operating limits for the FEL. Combinations outside of this matrix are unsafe and the beam is inhibited. The power limits range from no beam to 2 megawatts of electron beam power
Status and Future Developments in Large Accelerator Control Systems ( )
4 editions published in 2006 in English and held by 10 WorldCat member libraries worldwide
The hadron spectrum is computed in full QCD using domain-wall valence fermions on an improved staggered sea, for pion masses down to around $350(almost equal to)(/rm MeV)$. Emphasis is laid on the low-lying baryon spectrum. All possible baryon correlators obtainable from local and quasi-local quark sources are computed, using lattice group-theory methods Results are presented for the lowest-lying states in each isospin channel
Variation of Mechanical Properties of High RRR And Reactor Grade Niobium With Heat Treatments ( )
2 editions published in 2003 in English and held by 10 WorldCat member libraries worldwide
Superconducting rf cavities used as accelerating structures in particle accelerators are made from high purity niobium with residual resistance ratios greater than 250. Reactor grade niobium is also used to make wave-guide and/or end group components for these accelerating structures. The major impurities in this type of niobium are interstitially dissolved gases such as hydrogen, nitrogen, and oxygen in addition to carbon. After fabricating the niobium accelerating structures, they are subjected to heat treatments for several hours in vacuum at temperatures of up to 900 C for degassing hydrogen or up to 1400 C for improving the thermal conductivity of niobium considerably. These heat treatments are affecting the mechanical properties of niobium drastically. In this paper the variation of the mechanical properties of high purity and reactor grade niobium with heat treatments in a vacuum of (almost equal to) 10⁻⁶ Torr and temperatures from 600 C to 1250 C for periods of 10 to 6 hours are presented
