How Can We Avert Dangerous Climate Change?
J. Hansen
Recent analyses indicate that the amount of atmospheric CO2 required to cause dangerous climate change is at most 450 ppm, and likely less than that. Reductions of non-CO2 climate…
Present criteria for prophylactic ICD implantation: Insights from the EU-CERT-ICD (Comparative Effectiveness Research to Assess the Use of Primary ProphylacTic Implantable Cardioverter Defibrillators in EUrope) project
M. Zabel, S. Schlögl, A. Lubinski +45
BACKGROUND. The clinical effectiveness of primary prevention implantable cardioverter defibrillator (ICD) therapy is under debate. It is urgently needed to better identify patients…
Electromechanical properties of freestanding graphene functionalized with tin oxide (SnO2) nanoparticles
L. Dong, J. Hansen, P. Xu +5
Freestanding graphene membranes were functionalized with SnO2 nanoparticles. A detailed procedure providing uniform coverage and chemical synthesis is presented. Elemental composit…
Multipole Analysis and Application to Supernova Remnant X-ray Images
Denis A. Leahy, S. Ranasinghe, J. Hansen +2
We develop a multipole analysis method for images with a circular boundary, then apply it to supernova remnant (SNR) images. The morphology of SNR images is related to several fact…
Climate simulations for 1880-2003 with GISS modelE
J. Hansen, M. Sato, R. Ruedy +44
We carry out climate simulations for 1880-2003 with GISS modelE driven by ten measured or estimated climate forcings. An ensemble of climate model runs is carried out for each forc…
Microliter viscometry using a bright-field microscope: -DDM
M. A. Escobedo-Sanchez, J. P. Segovia-Gutiérrez, A. B. Zuccolotto-Bernez +5
Passive microrheology exploits the Brownian motion of colloidal tracer particles. From the mean-squared displacement (MSD) of the tracers, the bulk rheological and viscometric prop…
Target atmospheric CO2: Where should humanity aim?
J. Hansen, M. Sato, P. Kharecha +7
Paleoclimate data show that climate sensitivity is ~3 deg-C for doubled CO2, including only fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedba…
Acceleration of electrons in the plasma wakefield of a proton bunch
The AWAKE Collaboration, E. Adli, A. Ahuja +91
High energy particle accelerators have been crucial in providing a deeper understanding of fundamental particles and the forces that govern their interactions. In order to increase…
AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch
P. Muggli, E. Adli, R. Apsimon +104
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here is ready for systematic study of the seeded self-mod…
A magnetic spectrometer to measure electron bunches accelerated at AWAKE
J. Bauche, B. Biskup, M. Cascella +18
A magnetic spectrometer has been developed for the AWAKE experiment at CERN in order to measure the energy distribution of bunches of electrons accelerated in wakefields generated…
Experimental observation of proton bunch modulation in a plasma, at varying plasma densities
E. Adli, A. Ahuja, O. Apsimon +109
We give direct experimental evidence for the observation of the full transverse self-modulation of a relativistic proton bunch propagating through a dense plasma. The bunch exits t…
Dangerous human-made interference with climate: A GISS modelE study
J. Hansen, M. Sato, R. Ruedy +44
We investigate the issue of "dangerous human-made interference with climate" using simulations with GISS modelE driven by measured or estimated forcings for 1880-2003 and extended…
Target atmospheric CO2: Supporting material
J. Hansen, M. Sato, P. Kharecha +7
Additional material supporting the article "Target atmospheric CO2: Where should humanity aim?"
AWAKE, The Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN
E. Gschwendtner, E. Adli, L. Amorim +88
The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) aims at studying plasma wakefield generation and electron acceleration driven by proton bunches. It is a…
Path to AWAKE: Evolution of the concept
A. Caldwell, E. Adli, L. Amorim +118
This report describes the conceptual steps in reaching the design of the AWAKE experiment currently under construction at CERN. We start with an introduction to plasma wakefield ac…
