ABSTRACT Introduction Hyperglycemia during the perioperative period has generally been accepted as a contributor of poor outcomes in patients with diabetes mellitus undergoing surgery. Although an optimal glycemic range not clearly established literature, consensus among national medical organizations recommends serum glucose levels to be maintained less than 180 mg/dL period. Materials and Methods The primary purpose this evidence-based project was identify blood values obtained from adult...
We report progress on the R&D program for electron-cooling of Relativistic Heavy Ion Collider (RHIC). This electron cooler is designed to cool 100 GeV/nucleon at storage energy using 54 MeV electrons. The source will be a superconducting RF photocathode gun. accelerator recovery linac. frequency set 703.75 MHz. maximum bunch 9.38 MHz, with charge 20 nC. has following components: photoinjector and its photocathode, linac cavity, start-to-end beam dynamics magnetized electrons, cooling...
We present the design and parameters of an energy recovery linac (ERL) facility, which is under construction in Collider-Accelerator Department at BNL. This R&D facility has goal demonstrating CW operation ERL with average beam current range 0.1 - 1 ampere very high efficiency recovery. The possibility a future upgrade to two-pass also being considered. heart 5-cell 703.75 MHz super-conducting RF strong Higher Order Mode (HOM) damping. flexible lattice provides test-bed for exploring issues...
The physics interest in a luminosity upgrade of RHIC requires the development cooling-frontier facility. Detailed calculations were made electron cooling stored beams. This has been followed by beam dynamics simulations to establish feasibility creating necessary beam. accelerator will be superconducting Energy Recovery Linac (ERL). An intensive experimental R&D program engages various elements accelerator, as described 24 contributions 2007 PAC.
A transmission-type wattmeter can be formed utilizing the Hall effect to give wide-range multiplication over a frequency range extending from low audio-frequency region SHF band. At frequencies, device take form of thin wafer indium antimonide mounted in series with center leg cup core magnetic circuit. An employing such structure has been analyzed, constructed and tested. The zero 400 milliwatts when used 600-ohm circuit, displays error less than plus minus 3.5 per cent 100 6000 cps for...
The Rapid Cycling Medical Synchrotron (RCMS) is a second generation synchrotron. transverse beam size dominated by multiple scattering, if the incoming at 1 mm level. It takes 10 overlapping pulses 0.5 cm wide to scan tumor 5 with % flatness. Small sizes are critical for inexpensive gantries, since small beams permit use of small, lightweight, magnets which economical operate. RCMS achieves applying "strong focusing" optics emittance beam. Gantries and nozzles, control systems design discussed.
Anterior cervical discectomy and fusion (ACDF) is a common procedure with more than 137,000 cases in the United States (U.S.) each year. Historically, ACDF has been relatively safe despite encountering vital anatomical structures that can risk serious complications. One particularly dangerous sequela of lacerating vertebral artery (VA). While VA injuries are rare (0.5% cases), it crucial for surgeons to prevent this potentially deadly complication thorough knowledge anatomy. The commonly...
A key technology issue on the path to high-power FEL operation is demonstration of reliable, high-brightness, injector operation. We describe two ongoing programs produce 100 mA injectors as drivers for kW free-electron lasers. In one approach, in collaboration with Thomas Jefferson National Accelerator Facility, we are fabricating a 750 MHz superconducting RF cryomodule that will be integrated room-temperature DC photocathode gun and tested at Laboratory. other Los Alamos Laboratory,...
In this paper we present status and plans for the 20- MeV R&D energy recovery linac (ERL), which is under construction at Collider Accelerator Department BNL. The facility based on high current (up to 0.5 A of average current) super-conducting 2.5 RF gun,single-mode 5-cell about 20-m long return loop with very flexible lattice. ERL, planned commissioning in early 2009, aims address many outstanding questions relevant current, brightness energy-recovery linacs.
