The Two-Screen Measurement Setup to Indirectly Measure Proton Beam Self-Modulation in AWAKE

The goal of the first phase of the AWAKE \cite{AWAKE1,AWAKE2} experiment at CERN is to measure the self-modulation \cite{SMI} of the $\sigma_z = 12\,\rm{cm}$ long SPS proton bunch into microbunches after traversing $10\,\rm{m}$ of plasma with a plasma density of $n_{pe}=7\times10^{14}\,\rm{electrons/cm}^3$. The two screen measurement setup \cite{Turner2016} is a proton beam diagnostic that can indirectly prove the successful development of the self-modulation of the proton beam by imaging protons that got defocused by the transverse plasma wakefields after passing through the plasma, at two locations downstream the end of the plasma. This article describes the design and realization of the two screen measurement setup integrated in the AWAKE experiment. We discuss the performance and background response of the system based on measurements performed with an unmodulated Gaussian SPS proton bunch during the AWAKE beam commissioning in September and October 2016. We show that the system is fully commissioned and adapted to eventually image the full profile of a self-modulated SPS proton bunch in a single shot measurement during the first phase of the AWAKE experiment.Comment: 5 pages 8 figure

Multi-Instantons and Multi-Cuts

We discuss various aspects of multi-instanton configurations in generic multi-cut matrix models. Explicit formulae are presented in the two-cut case and, in particular, we obtain general formulae for multi-instanton amplitudes in the one-cut matrix model case as a degeneration of the two-cut case. These formulae show that the instanton gas is ultra-dilute, due to the repulsion among the matrix model eigenvalues. We exemplify and test our general results in the cubic matrix model, where multi-instanton amplitudes can be also computed with orthogonal polynomials. As an application, we derive general expressions for multi-instanton contributions in two-dimensional quantum gravity, verifying them by computing the instanton corrections to the string equation. The resulting amplitudes can be interpreted as regularized partition functions for multiple ZZ-branes, which take into full account their back-reaction on the target geometry. Finally, we also derive structural properties of the trans-series solution to the Painleve I equation.Comment: 34 pages, 3 figures, JHEP3.cls; v2: added references, minor changes; v3: added 1 reference, more minor changes, final version for JMP; v4: more typos correcte

Understanding Public Participation in Forest Planning in Australia: How Can We Learn From Each Other?

A round table discussion on public participation in forest planning, during a meeting of the Forest Planners Working group in February 1997 at the ANU, revealed a wealth of unexplored and unrecorded experiences of public participation across the country. It became clear that public participation, which is a legal requirement in most states, was perceived and implemented in different ways by different government agencies to various degrees of success. The first author who attended part of the meeting, could sense some ambient frustration at the ever increasing energy and resources devoted by the various forest agencies to involve the public in planning matters, while the very same 'public' never seemed to be satisfied and was making more and more unreasonable demands. Subsequent discussions with NRE Victoria, DNR Queensland, Forestry Tasmania and CALM WA reiterated that a collaborative effort to systematically record and analyse the experiences of public participation in forestry planning could deliver concrete learning outputs valid for all. Thanks to a grant from NRE Victoria, DNR Queensland and the ANU we designed a research program. It was based on reviewing relevant literature on participatory management processes and conducting field surveys to 1) develop an analytical framework , 2) record field realities in 4 states Victoria, Queensland, Tasmania, Western Australia 3) analyse the processes in those states and 4) put forward ideas and recommendations for further consultation processes. This paper reports on the various findings of the study.This research was made possible thanks to a grant from the ANU, DNR Queensland and NRE Victoria and to logistical support from Forestry Tasmania and CALM

The Role of Healthcare Informatics Competencies (HICs) and IT Capabilities for Service Innovation in Paramedicine

Paramedic services in the developed world face several problems, often manifesting in unavailability of ambulances, and other negative effects. Paramedic services are innovating with new service delivery models and technologies, yet the evidence that guides paramedic services in these processes is lacking. The purpose of this paper is to determine how paramedic services innovate, and how that innovation is influenced by technology in particular. This research integrates the Dynamic Capabilities, IT Capabilities and Health Informatics Competencies approaches in a multilevel model to understand this issue in a sample of Canadian paramedic services (n=43). The results suggest that paramedics with higher competencies related to identifying areas for technology understanding and application contribute to the ability of a paramedic service to respond to environmental changes. The relationship between IT and paramedic leadership, and the business expertise of the information technology staff also have an impact on the ability to change

The Effects of Visual Search Efficiency on Object-Based Attention

The attentional prioritization hypothesis of object-based attention (Shomstein & Yantis in Perception & Psychophysics, 64, 41–51, 2002) suggests a two-stage selection process comprising an automatic spatial gradient and flexible strategic (prioritization) selection. The combined attentional priorities of these two stages of object-based selection determine the order in which participants will search the display for the presence of a target. The strategic process has often been likened to a prioritized visual search. By modifying the double-rectangle cueing paradigm (Egly, Driver, & Rafal in Journal of Experimental Psychology: General, 123, 161–177, 1994) and placing it in the context of a larger-scale visual search, we examined how the prioritization search is affected by search efficiency. By probing both targets located on the cued object and targets external to the cued object, we found that the attentional priority surrounding a selected object is strongly modulated by search mode. However, the ordering of the prioritization search is unaffected by search mode. The data also provide evidence that standard spatial visual search and object-based prioritization search may rely on distinct mechanisms. These results provide insight into the interactions between the mode of visual search and object-based selection, and help define the modulatory consequences of search efficiency for object-based attention
