Ionization profile monitors (IPMs) are installed in the Fermilab Booster, Main Injector and Tevatron. They are used routinely for injection matching measurements. For emittance measurements the IPMs have played a secondary role to the Flying Wires, with the exception of the Booster (where it is the only profile diagnostics). As Fermilab is refocusing its attention on the intensity frontier, non...
BACKGROUND Herpes zoster vaccine (ZV) was administered as a second dose to 200 participants ≥ 70 years old who had received a dose of ZV ≥ 10 years previously (NCT01245751). METHODS Varicella zoster virus (VZV) antibody titers (measured by a VZV glycoprotein-based enzyme-linked immunosorbent assay [gpELISA]) and levels of interferon γ (IFN-γ) and interleukin 2 (IL-2; markers of VZV-specific c...
Despite the effectiveness of vaccines in dramatically decreasing the number of new infectious cases and severity of illnesses, imperfect vaccines may not completely prevent infection. This is because the immunity afforded by these vaccines is not complete and may wane with time, leading to resurgence and epidemic outbreaks notwithstanding high levels of primary vaccination. To prevent an endemi...
Immune response of man to various Habu-venom toxoids with different potencies was investigated. A linear relationship was observed between circulating anti-HRI and the amount of HRI toxoid used for the basic immunization. A highly purified toxoid was 2.5 times more effective in man than partially purified ones, when compared on the basis of the immunizing unit determined in guinea pigs. Out of ...
BACKGROUND Attention-deficit hyperactivity disorder (ADHD) is a mental disorder beginning in childhood, and about half of patients have symptoms lasting into adulthood. Adult ADHD causes various impairments of emotional, self-esteem, and executive function and life quality aspects. Furthermore, adverse outcomes include academic and occupational failures, traffic accidents and substance abuse, w...
The Fermilab Booster is a rapid-cycling synchrotron which accelerates 84 bunches of protons from 401 MeV to 8 GeV for injection into the Fermilab Main Injector. The entire circumference, ie., all RF buckets, of the Booster is filled. At extraction, a kicker deflects the beam into the extraction channel. The kicker risetime is long enough so that several of the bunches do not receive the full ki...
The Gun Test Facility (GTF) consists of a 1.6-cell S-band photocathode gun and a single SLAC 3-m accelerating structure (booster) followed by a beam dump. The beam components are housed in the SPEAR synchrotron injector vault in Building 140. Outside the vault are the two XK5 klystrons/modulators that provide the rf power, and the laser shack and control area. The laser shack contains a high-po...
The tracking and simulation code Accsim has recently been upgraded with new treatments of transverse space charge, one based on a conventional multiple-Fourier-transform technique and another using a new hybrid-fast-multipole (HFM) method. We present the application of the code to the study of multiturn injection in the CERN PS Booster in its LHC-injector-chain operation scenario. In particular...
1 Overview Electricity generation from coal, natural gas, oil and nuclear sources involves the use of large volumes of process water. Two significant water-related issues confront the energy industry. The first involves biofouling of process surfaces and other power plant structures, leading to reduced energy efficiency and increased operational costs. A second challenge involves the accumulati...
