Lanthanide-based nanophosphors (NPhs) are herein developed as contrast agents for spectral X-ray imaging, highlighting the chemical, macromolecular and structural differences derived from ligand exchange on computed tomography (CT) solvent dispersibility. Taking advantage of ability imaging with photon-counting detectors to perform image acquisition, analysis, processing at different energy windows (bins), enhanced signal our K-edge materials was derived, improving sensitivity CT...
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...
High-bunch-charge photoemission electron-sources operating in a continuous wave (CW) mode are required for many advanced applications of particle accelerators, such as electron coolers hadron beams, electron-ion colliders, and free-electron lasers. Superconducting RF (SRF) has several advantages over other electron-gun technologies CW it offers higher acceleration rate potentially can generate bunch charges average beam currents. A 112 MHz SRF photoinjector (gun) was developed at Brookhaven...
Superconducting rf (SRF) photoinjectors are one of the most promising devices for generating continuous wave (CW) electron beams with record high brightness. Ultrahigh vacuum SRF guns provides long lifetime quantum efficiency (QE) photocathodes, while technology accelerating gradients exceeding $10\text{ }\text{ }\mathrm{MV}/\mathrm{m}$. It is especially true low frequency where electrons generated at photocathodes crest voltage. Two main physics challenges their compatibility QE and...
We develop a model in which firm's manager can voluntarily disclose to privately-informed investors. show that, equilibrium, the only discloses sufficiently favorable news. If is known be informed but disclosure costly, probability of increases with market liquidity and stock trades at discount relative expected cash flows. However, when investors are uncertain about whether informed, decrease liquidity, trade premium Moreover, contrary common intuition, ex-ante public information crowd more...
The recent successful commissioning and operation of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) requires injection gold ions specified energy intensity with longitudinal transverse emittances small enough to meet luminosity requirements collider. beams desired characteristics are provided by a series three accelerators, Tandem, Booster AGS. current status performance these accelerators reviewed in this paper.
Operational aspects of the RHIC RF system are described. To date three different beam combinations have been collided for physics production: gold-gold, deuteron-gold, and proton-proton(polarized). facilitate this flexibility systems two rings independent self-sufficient. Techniques to cope with problems such as, injection/capture, loading, bunch shortening, noise evolved explained.
The BNL SRF gun cavity operated well in CW mode up to 2 MV. However, its performance suffered due multipacting the quarter-wavelength choke joint. A new multipacting-free cathode stalk was designed and conditioned. This paper describes RF thermal design of conditioning results.
The Low Energy RHIC electron Cooling (LEReC) is under development at BNL to improve luminosity low energies. It will consist of a short linac and two cooling sections, one for blue yellow rings. For the first stage project, LEReC-I, we install 704 MHz superconducting RF cavity three normal conducting cavities operating 9 MHz, 2.1 GHz. SRF boost beam energy up 2 MeV. warm be used correct spread introduced in cavity. paper describes layouts systems, their parameters status.
