Oral History Interview with Albert Sanders, June 22, 2012 transcript

Oral History Interview with Albert Sanders, June 22, 2012

The National Museum of the Pacific War presents an oral interview with Albert Sanders. Sanders joined the Army Air Forces in October 1942 and earned his wings in April 1944. After learning to fly B-24s, he arrived in England with his crew as part of the 458th Bomb Group. From there he made raids over Germany, twice making emergency landings in Belgium after being shot up. He transitioned into being a lead crew pilot, heading up a tight formation of 36 bombers. Sanders had flown 18 missions by the time the war ended. He and his crew flew home, stopping for fuel and wine in the Azores. He was also transporting 20 soldiers who were so eager to land that they crowded the front of the plane, shifting the load and causing an extremely rough and dangerous landing. That was the last time Sanders ever piloted an aircraft.

Generic Model Host System Design (open access)

Generic Model Host System Design

There are many simulation codes for accelerator modelling; each one has some strength but not all. A platform which can host multiple modelling tools would be ideal for various purposes. The model platform along with infrastructure support can be used not only for online applications but also for offline purposes. Collaboration is formed for the effort of providing such a platform. In order to achieve such a platform, a set of common physics data structure has to be set. Application Programming Interface (API) for physics applications should also be defined within a model data provider. A preliminary platform design and prototype is discussed.

Studies of Space Charge Effects in the Proposed CERN PS2 (open access)

Studies of Space Charge Effects in the Proposed CERN PS2

A new proton synchrotron, the PS2, is under design study to replace the current proton synchrotron at CERN for the LHC upgrade. Nonlinear space charge effects could cause significant beam emittance growth and particle losses and limit the performance of the PS2. In this paper, we report on studies of the potential space-charge effects at the PS2 using three-dimensional self-consistent macroparticle tracking codes, IMPACT, MaryLie/IMPACT, and Synergia. We will present initial benchmark results among these codes. Effects of space-charge on the emittance growth, especially due to synchrotron coupling, aperture sizes, initial painted distribution, and RF ramping scheme will also be discussed.

Breaking the Attosecond, Angstrom and TV/M Field Barriers with Ultra-Fast Electron Beams (open access)

Breaking the Attosecond, Angstrom and TV/M Field Barriers with Ultra-Fast Electron Beams

Recent initiatives at UCLA concerning ultra-short, GeV electron beam generation have been aimed at achieving sub-fs pulses capable of driving X-ray free-electron lasers (FELs) in single-spike mode. This use of very low Q beams may allow existing FEL injectors to produce few-100 attosecond pulses, with very high brightness. Towards this end, recent experiments at the LCLS have produced {approx}2 fs, 20 pC electron pulses. We discuss here extensions of this work, in which we seek to exploit the beam brightness in FELs, in tandem with new developments in cryogenic undulator technology, to create compact accelerator-undulator systems that can lase below 0.15 {angstrom}, or be used to permit 1.5 {angstrom} operation at 4.5 GeV. In addition, we are now developing experiments which use the present LCLS fs pulses to excite plasma wakefields exceeding 1 TV/m, permitting a table-top TeV accelerator for frontier high energy physics applications.

Defining How a Microbial Cell Senses and Responds to a Redox Active Environment (open access)

Defining How a Microbial Cell Senses and Responds to a Redox Active Environment

This grant was for four years, and the work was designed to look at the mechanisms of extracellular electron transfer by the dissimilatory iron reducing bacteria Shewanella oneidensis MR-1, and other closely related Shewanella strains and species. During this work, we defined many of the basic physiological and biochemical properties of the Shewanella group, Much of which was summarized in review articles. We also finished and published the genome sequence of strain MR-1, the first of the shewanellae to have its genome sequenced. Control at the transcriptional and translational level was studied in collaboration with colleagues at PNNL and ANL. We utilized synchrotron X-ray radiation to image both the bacteria and the metal oxide particles via a technique called STXM, synchrotron X-ray absorption (ref. No.9), and X-ray microbeam analysis. We purified several of the cytochromes involved with metal reduction, and improved gene annotation of the MR-1 genome. The conductive appendages (nanowires) of MR-1 were described and characterized. Comparative genomics and biochemistry revealed that the pathway for the utilization of N-acetyl glucosamine in the various strains of Shewanella exhibited great variability, and had a number of previously unknown genes.

High-speed, multi-channel detector readout electronics for fast radiation detectors (open access)

High-speed, multi-channel detector readout electronics for fast radiation detectors

In this project, we are developing a high speed digital spectrometer that a) captures detector waveforms at rates up to 500 MSPS b) has upgraded event data acquisition with additional data buffers for zero dead time operation c) moves energy calculations to the FPGA to increase spectrometer throughput in fast scintillator applications d) uses a streamlined architecture and high speed data interface for even faster readout to the host PC These features are in addition to the standard functions in our existing spectrometers such as digitization, programmable trigger and energy filters, pileup inspection, data acquisition with energy and time stamps, MCA histograms, and run statistics. In Phase I, we upgraded one of our existing spectrometer designs to demonstrate the key principle of fast waveform capture using a 500 MSPS, 12 bit ADC and a Xilinx Virtex-4 FPGA. This upgraded spectrometer, named P500, performed well in initial tests of energy resolution, pulse shape analysis, and timing measurements, thus achieving item (a) above. In Phase II, we are revising the P500 to build a commercial prototype with the improvements listed in items (b)-(d). As described in the previous report, two devices were built to pursue this goal, named the Pixie-500 and the …

X-Band RF Gun Development (open access)

X-Band RF Gun Development

In support of the MEGa-ray program at LLNL and the High Gradient research program at SLAC, a new X-band multi-cell RF gun is being developed. This gun, similar to earlier guns developed at SLAC for Compton X-ray source program, will be a standing wave structure made of 5.5 cells operating in the pi mode with copper cathode. This gun was designed following criteria used to build SLAC X-band high gradient accelerating structures. It is anticipated that this gun will operate with surface electric fields on the cathode of 200 MeV/m with low breakdown rate. RF will be coupled into the structure through a final cell with symmetric duel feeds and with a shape optimized to minimize quadrupole field components. In addition, geometry changes to the original gun, operated with Compton X-ray source, will include a wider RF mode separation, reduced surface electric and magnetic fields.

Global Fits of the Minimal Universal Extra Dimensions Scenario (open access)

Global Fits of the Minimal Universal Extra Dimensions Scenario

In theories with Universal Extra-Dimensions (UED), the {gamma}{sub 1} particle, first excited state of the hypercharge gauge boson, provides an excellent Dark Matter (DM) candidate. Here we use a modified version of the SuperBayeS code to perform a Bayesian analysis of the minimal UED scenario, in order to assess its detectability at accelerators and with DM experiments. We derive in particular the most probable range of mass and scattering cross sections off nucleons, keeping into account cosmological and electroweak precision constraints. The consequences for the detectability of the {gamma}{sub 1} with direct and indirect experiments are dramatic. The spin-independent cross section probability distribution peaks at {approx} 10{sup -11} pb, i.e. below the sensitivity of ton-scale experiments. The spin-dependent cross-section drives the predicted neutrino flux from the center of the Sun below the reach of present and upcoming experiments. The only strategy that remains open appears to be direct detection with ton-scale experiments sensitive to spin-dependent cross-sections. On the other hand, the LHC with 1 fb{sup -1} of data should be able to probe the current best-fit UED parameters.

Intermediate Energy Nuclear Physics Program (open access)

Intermediate Energy Nuclear Physics Program

The originally proposed and funded research activities followed two major areas of study: semileptonic probes of the hadronic neutral current and charm production. The charm production work revolved around the Jefferson Lab experiment E03-008, 'Sub-threshold J/psi Photoprouction', which ran in late 2004. The PI was a co-spokesperson for the experiment. For the three year renewal proposal starting in 2007, the scope and size of the research project changed and increased. In addition to the parity violating studies, the PI had well defined lead roles in a series experiments nucleon spin-structure functions.

Plot/SurfW: Plotting Utility for EDGE2D Output (open access)

Plot/SurfW: Plotting Utility for EDGE2D Output

This report describes a utility that was developed to display EDGE2D results. The utility is focused on results that relate to impurity density, velocity, and particle fluxes in the SOL and divertor. Due to the complicated nature of 2D impurity sources, the concentration of the thermal force near the separatrix and near the divertor entrance, the impurity flow pattern and impurity densities are not necessarily easy to visualize. Thus, we wanted a utility that allowed simple and quick visualization of the impurity behavior. In order to achieve this we overlaid the divertor hardware for plots inside the divertor and we expanded the appearance of the main chamber SOL by plotting distance along the field lines vs. SOL depth with the density (or velocity or flux or other quantity) the false colour. Also, we allowed for the plotted variable to be a function of the other EDGE2D result variables. __________________________________________________
