Hydrodynamic computational modelling and simulations of collisional shock waves in gas jet targets

We study the optimization of collisionless shock acceleration of ions based on hydrodynamic modelling and simulations of collisional shock waves in gaseous targets.The models correspond to the specifications required for experiments with the CO2 laser at the Accelerator Test Facility at Brookhaven National Laboratory and the Vulcan Petawatt system at Rutherford Appleton Laboratory.In both cases,a laser prepulse is simulated to interact with hydrogen gas jet targets.It is demonstrated that by controlling the pulse energy,the deposition position and the backing pressure,a blast wave suitable for generating nearly monoenergetic ion beams can be formed.Depending on the energy absorbed and the deposition position,an optimal temporal window can be determined for the acceleration considering both the necessary overdense state of plasma and the required short scale lengths for monoenergetic ion beam production.

Innovative Education and Training in high power laser plasmas(PowerLaPs) for plasma physics, high power laser-matter interactions and high energy density physics-theory and experiments

The Erasmus Plus programme’Innovative Education and Training in high power laser plasmas’,otherwise known as PowerLaPs,is described.The PowerLaPs programme employs an innovative paradigm in that it is a multi-centre programme where teaching takes place in five separate institutes with a range of different aims and styles of delivery.The ’in class’ time is limited to four weeks a year,and the programme spans two years.PowerLaPs aims to train students from across Europe in theoretical,applied and laboratory skills relevant to the pursuit of research in laserplasma interaction physics and inertial confinement fusion(ICF).Lectures are intermingled with laboratory sessions and continuous assessment activities.The programme,which is led by workers from the Technological Educational Institute(TEI)of Crete,and supported by co-workers from the Queen’s University Belfast,the University of Bordeaux,the Czech Technical-University in Prague,Ecole Polytechnique,the University of Ioannina,the University of Salamanca and the University of York,has just completed its first year.Thus far three Learning Teaching Training(LTT)activities have been held,at the Queen’s University Belfast,the University of Bordeaux and the Centre for Plasma Physics and Lasers(CPPL)of TEI Crete.The last of these was a two-week long Intensive Programme(IP),while the activities at the other two universities were each five days in length.Thus far work has concentrated upon training in both theoretical and experimental work in plasma physics,high power laser-matter interactions and high energy density physics.The nature of the programme will be described in detail and some metrics relating to the activities carried out to date will be presented.

Innovative education and training in high power laser plasmas(PowerLaPs) for plasma physics, high power laser matter interactions and high energy density physics: experimental diagnostics and simulations

The second and final year of the Erasmus Plus programme’Innovative Education and Training in high power laser plasmas’,otherwise known as PowerLaPs,is described.The PowerLaPs programme employs an innovative paradigm in that it is a multi-centre programme,where teaching takes place in five separate institutes with a range of different aims and styles of delivery.The’in-class’time is limited to 4 weeks a year,and the programme spans 2 years.PowerLaPs aims to train students from across Europe in theoretical,applied and laboratory skills relevant to the pursuit of research in laser plasma interaction physics and inertial confinement fusion.Lectures are intermingled with laboratory sessions and continuous assessment activities.The programme,which is led by workers from the Hellenic Mediterranean University and supported by co-workers from the Queen’s University Belfast,the University of Bordeaux,the Czech Technical University in Prague,Ecole Polytechnique,the University of Ioannina,the University of Salamanca and the University of York,has just finished its second and final year.Six Learning Teaching Training activities have been held at the Queen’s University Belfast,the University of Bordeaux,the Czech Technical University,the University of Salamanca and the Institute of Plasma Physics and Lasers of the Hellenic Mediterranean University.The last of these institutes hosted two 2-week-long Intensive Programmes,while the activities at the other four universities were each 5 days in length.In addition,a’Multiplier Event’was held at the University of Ioannina,which will be briefly described.In this second year,the work has concentrated on training in both experimental diagnostics and simulation techniques appropriate to the study of plasma physics,high power laser matter interactions and high energy density physics.The nature of the programme will be described in detail,and some metrics relating to the activities carried out will be presented.In particular,this paper will focus on the overall assessment of the programme.
