Laboratory realization of relativistic pair-plasma beams
/ Arrowsmith, C.D. (Oxford U.) ; Simon, P. (CERN ; Darmstadt, GSI) ; Bilbao, P.J. (Lisbon, IST) ; Bott, A.F. A. (Oxford U.) ; Burger, S. (CERN) ; Chen, H. (LLNL, Livermore) ; Cruz, F.D. (Lisbon, IST) ; Davenne, T. (Rutherford) ; Efthymiopoulos, I. (CERN) ; Froula, D.H. (Rochester U.) et al.
Relativistic electron-positron plasmas are ubiquitous in extreme astrophysical environments such as black holes and neutron star magnetospheres, where accretion-powered jets and pulsar winds are expected to be enriched with such pair plasmas. Their behaviour is quite different from typical electron-ion plasmas due to the matter-antimatter symmetry of the charged components and their role in the dynamics of such compact objects is believed to be fundamental.

Cold atoms in space: community workshop summary and proposed road-map
/ Alonso, Iván (Balearic Islands U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Altschul, Brett (South Carolina U.) ; Araújo, Henrique (Imperial Coll., London) ; Arduini, Gianluigi (CERN) ; Arlt, Jan (Aarhus U.) ; Badurina, Leonardo (King's Coll. London) ; Balaž, Antun (Belgrade, Inst. Phys.) ; Bandarupally, Satvika (Florence U. ; INFN, Florence) ; Barish, Barry C. (LIGO Lab., Caltech) et al.
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. [...]

Generating ultra-dense pair beams using 400 GeV/c protons
/ Arrowsmith, C.D. (Oxford U.) ; Shukla, N. (CINECA) ; Charitonidis, N. (CERN) ; Boni, R. (Rochester U.) ; Chen, H. (LLNL, Livermore) ; Davenne, T. (Rutherford) ; Dyson, A. (Oxford U.) ; Froula, D.H. (Rochester U.) ; Gudmundsson, J.T. (Iceland U. ; Royal Inst. Tech., Stockholm) ; Huffman, B.T. (Oxford U.) et al.
A previously unexplored experimental scheme is presented for generating low-divergence, ultra-dense, relativistic, electron-positron beams using 400 GeV/c protons available at facilities such as HiRadMat and AWAKE at CERN. Preliminary Monte-Carlo and Particle-in-cell simulations demonstrate the possibility of generating beams containing $10^{13}-10^{14}$ electron-positron pairs at sufficiently high densities to drive collisionless beam-plasma instabilities, which are expected to play an important role in magnetic field generation and the related radiation signatures of relativistic astrophysical phenomena.

Observed proton beam induced disruption of a tungsten powder sample at CERN
/ Davenne, T (Rutherford) ; Loveridge, P (Rutherford) ; Bingham, R (Rutherford ; Strathclyde U.) ; Wark, J (University Coll. London) ; Back, J J (Warwick U.) ; Caretta, O (Rutherford) ; Densham, C (Rutherford) ; O'Dell, J (Rutherford) ; Wilcox, D (Rutherford) ; Fitton, M (Rutherford)
Fluidized tungsten powder has been proposed as a potential target technology for particle accelerator applications with very high power highly focused pulsed beams. This has motivated a series of experiments carried out at the HiRadMat facility at CERN to study the response of a tungsten powder sample to an impinging high energy proton beam pulse. [...]

Simulation of density measurements in plasma wakefields using photo acceleration
/ Kasim, Muhammad Firmansyah (John Adams Institute, Oxford) ; Ratan, Naren (Clarendon Lab, Oxford University) ; Ceurvorst, Luke (Clarendon Lab, Oxford University) ; Sadler, James (Clarendon Lab, Oxford University) ; Burrows, Philip N (John Adams Institute, Oxford) ; Trines, Raoul (STFC Rutherford Appleton Lab, Didcot) ; Holloway, James (University College London) ; Wing, Matthew (University College London) ; Bingham, Robert (STFC Rutherford Appleton Lab, Didcot) ; Norreys, Peter (Oxford University and STFC Rutherford Appleton Lab, Didcot)
One obstacle in plasma accelerator development is the limitation of techniques to diagnose and measure plasma wakefield parameters. In this paper, we present a novel concept for the density measurement of a plasma wakefield using photon acceleration, supported by extensive particle in cell simulations of a laser pulse that copropagates with a wakefield.

AWAKE: A Proton-Driven Plasma Wakefield Acceleration Experiment at CERN
