The BEPCII commissioning started in November of 2006. After two phases commissioning, the current of both beam for colliding mode have been above 500mA, and the luminosity is above 10^32. The machine has been opened to the synchrotron radiation users. The beam cuurent for the synchrotron radiation mode has get the design goal 250mA, the topoff injection mode has been realized. In this talk, the brief introduction about the commissioning process and results will be shown. The third phase goal will be presented also.\n<\/td>\n<\/tr>\n

The Large Hadron Collider (LHC) will be the world’s next energy-frontier machine, bringing into collision counter-rotating proton beams of about 3000 bunches each at a centre-of-mass energy of 14 TeV with a design luminosity of 1e34 \/cm^2\/s. About 25 years after its original conception, the LHC will start beam operation later this year. At the same time upgrade scenarios for the LHC and its injectors are being finalized, which could boost the LHC luminosity by another order of magnitude on the 10-15 years time scale.
\nAfter a brief overview of the LHC main features, this talk will report on the progress of the LHC hardware commissioning, the further 2008 schedule including beam commissioning and first collisions, and the LHC upgrade plans.\n<\/td>\n<\/tr>\n

With a model-independent analysis (MIA) for precision linear orbit measurement and providing almost unlimited Green’s functions, we have been able to obtain accurate lattice models, called virtual machines that match the PEP-II Low-Energy Ring (LER) or High-Energy Ring (HER) in optics. Once a virtual machine is obtained, we may try to find and adjust one or two magnets with noticeable differences from expectation.
\nHowever, a more common practice is to search for an easily-approachable better-optics model by pre-selecting and fitting a group of normal and skew quadrupoles and\/or orbit correctors (for sextupole bumps). The corresponding magnet changes are then dialed into the real accelerator. These procedures have been successfully applied to PEP-II LER and HER for beta beat fixing, coupling and dispersion correction, large working tune jump, IP optics optimization, and have helped PEP-II overcome milestones in luminosity enhancement.\n<\/td>\n<\/tr>\n

2007\/9\/14<\/td>\n(Fri.)<\/td>\n15:00-16:00<\/td>\nMeeting Room of 1-Go kan (Danwa-shitsu)<\/td>\nDr. Zeke Insepov (ANL)<\/td>\nIntroduction to energetic ion interaction with surface<\/td>\n\u5ddd\u5408\n<\/td>\n<\/tr>\n
Introduction to surface erosion and modification by energetic highly-charged and cluster ions will be given that are important in the development of semiconductor devices, TeV accelerators, fission and fusion reactors, magnetic storage, and in the development of a future Extreme Ultra-Violet Lithography device. Gas cluster ion beam (GCIB) surface treatment can significantly mitigate the high-gradient electric vacuum breakdown of rf-cavities. GCIB can also mitigate Q-slope drop in superconducting Nb-cavities. Various mechanisms of the Highly-charged ion (HCI) energy transfer into the solid target, such as hollow atom formation, charge screening and neutralization, shock wave generation, and sputtering were analyzed. Surface erosions caused by GCIB, HCI bombardments, and by low energy He+ and H+ ions typical for fission and fusion devices were studied by using Molecular Dynamics simulation. A He bubble splashing mechnaism of liquid Li containing was developed, and surface erosion was simulated. The mechanism of bubble explosion could significantly contribute to the surface erosion at high ion fluxes and explain the existing experimental results.\n<\/td>\n<\/tr>\n

\nSince the first idea of an ion source using laser ablation plasma arose, almost forty years has already passed. It was found that the laser plasma could provide ultra intense beam with high charge state easily.
\nIn spite of this advantage, the laser ion source (LIS) has not been accepted by a major stream of the accelerator field. Once the laser plasma produced, it is hard to control the pulse structure. However, accumulated research results by many groups capable us to provide high quality various ions from LIS now.
\nDue to its simple structure, the LIS suits not only for a large accelerator complexes but also for small facilities. The history of the LIS and a project for LHC at CERN will be briefly introduced. Also a planned LIS project in RHIC will be mentioned.
\n Then recent activities about direct plasma injection scheme (DPIS) will be explained.
\n lastly, other works related to LIS will be summarized.<\/td>\n<\/tr>\n

The BEPCII commissioning started in November of 2006. After two phases commissioning, the current of both beam for colliding mode have been above 500mA, and the luminosity is above 10^32. The machine has been opened to the synchrotron radiation users. The beam cuurent for the synchrotron radiation mode has get the design goal 250mA, the topoff injection mode has been realized. In this talk, the brief introduction about the commissioning process and results will be shown. The third phase goal will be presented also.\n<\/td>\n<\/tr>\n

The Large Hadron Collider (LHC) will be the world’s next energy-frontier machine, bringing into collision counter-rotating proton beams of about 3000 bunches each at a centre-of-mass energy of 14 TeV with a design luminosity of 1e34 \/cm^2\/s. About 25 years after its original conception, the LHC will start beam operation later this year. At the same time upgrade scenarios for the LHC and its injectors are being finalized, which could boost the LHC luminosity by another order of magnitude on the 10-15 years time scale.
\nAfter a brief overview of the LHC main features, this talk will report on the progress of the LHC hardware commissioning, the further 2008 schedule including beam commissioning and first collisions, and the LHC upgrade plans.\n<\/td>\n<\/tr>\n

With a model-independent analysis (MIA) for precision linear orbit measurement and providing almost unlimited Green’s functions, we have been able to obtain accurate lattice models, called virtual machines that match the PEP-II Low-Energy Ring (LER) or High-Energy Ring (HER) in optics. Once a virtual machine is obtained, we may try to find and adjust one or two magnets with noticeable differences from expectation.
\nHowever, a more common practice is to search for an easily-approachable better-optics model by pre-selecting and fitting a group of normal and skew quadrupoles and\/or orbit correctors (for sextupole bumps). The corresponding magnet changes are then dialed into the real accelerator. These procedures have been successfully applied to PEP-II LER and HER for beta beat fixing, coupling and dispersion correction, large working tune jump, IP optics optimization, and have helped PEP-II overcome milestones in luminosity enhancement.\n<\/td>\n<\/tr>\n

SLAC has long been a leader in accelerator modeling technology transfer. For over three decades, Dr. Martin Lee has engaged in the transfer of SLAC’s accelerator modeling technology to the outside world. Recently, he has been working on bringing novel modeling technology to SLAC. Since joining the laboratory’s Office of Technology Transfer in July 2007 as an industrial collaborations engineering physicist, he began to play the role as the "Ambassador of Tech Transfer"-at-large. In this talk, Dr. Lee will share his experiences with the "Modeling of Beam Lifetime using a Combined First-Principles Model and a Neural Network"–a current collaborative project with Pavilion Technology.\n<\/td>\n<\/tr>\n

Introduction to surface erosion and modification by energetic highly-charged and cluster ions will be given that are important in the development of semiconductor devices, TeV accelerators, fission and fusion reactors, magnetic storage, and in the development of a future Extreme Ultra-Violet Lithography device. Gas cluster ion beam (GCIB) surface treatment can significantly mitigate the high-gradient electric vacuum breakdown of rf-cavities. GCIB can also mitigate Q-slope drop in superconducting Nb-cavities. Various mechanisms of the Highly-charged ion (HCI) energy transfer into the solid target, such as hollow atom formation, charge screening and neutralization, shock wave generation, and sputtering were analyzed. Surface erosions caused by GCIB, HCI bombardments, and by low energy He+ and H+ ions typical for fission and fusion devices were studied by using Molecular Dynamics simulation. A He bubble splashing mechnaism of liquid Li containing was developed, and surface erosion was simulated. The mechanism of bubble explosion could significantly contribute to the surface erosion at high ion fluxes and explain the existing experimental results.\n<\/td>\n<\/tr>\n
