Compton scattering techniques for the measurement of the transverse beam size of particle beams at future linear colliders
21st Beam Dynamics Workshop on Laser-Beam Interactions, Meeting locationState University of New York, Stony Brook, NY, USA, 11 Jun 2001 - 15 Jun 20012001-06-112001-06-15 6 pp. (2001) [10.3204/PUBDB-2017-12401]  GO
At several locations of the beam delivery system (BDS) of a future linear collider (FLC),beam spot sizes ranging from several hundreds to a fewmicrometers have to be measured.The large demagnification of the beam in the BDS and the high beam power puts extremeconditions on any measuring device. With conventional techniques at their operational limit inFLC scenarios, newmetho ds for the detection of the transverse beam size have to be developed.Laser based techniques are capable of measuring high power beams with sizes in the micrometerrange.

Laboratory astrophysics:Bell’s instability, a cosmic-ray driven magnetic field fluctuation
9. DESY Beschleuniger Ideenmarkt, Meeting locationHamburg, Germany, 10 Oct 2017 - 10 Oct 20172017-10-102017-10-10
With the progresses of experimental technologies, laboratory astrophysics has become an alternative method in astrophysics studies besides the classical observations and numerical simulations. Via the connection between astrophysics and laboratory experiments, laboratory astrophysics seeks to expand our understanding of physical processes by simulating the extreme astrophysical environments in the laboratory.

Preparatory simulation studies for the laboratory experiment of cosmic-ray driven magnetic field fluctuations
Computational Plasma Physics Conference 2017, Meeting locationYork, UK, 20 Nov 2017 - 22 Nov 20172017-11-202017-11-22
For the source of PeV-scale high energy cosmic ray particles, the diffusive shock acceleration process at the forward shocks of supernova remnants is considered as the principal mechanism. For efficient acceleration, a nonresonant instability driven by cosmic ray current is suggested as a candidate for providing the required magnetic turbulence in the upstream region of the shock [1].

Background & SiD Occupancy Studies for the ILC250 stage
International Workshop on Future Linear Colliders, LCWS2017, Meeting locationStrasbourg, France, 22 Oct 2017 - 27 Oct 20172017-10-222017-10-27  GO
The recent change request for the International Linear Collider has decided to change the beam parameters for the 250 GeV stage in order to increase the achievable luminosity.This change in the beam parameter set also increases the beam background arising from enhanced beam-beam interactions.Focus of this study is the impact of the increased background on the occupancy of the SiD detector..

The FLASHForward project at DESY is an innovative beam-driven plasma-wakefield acceleration experiment, aiming to accelerate electron beams to GeV energies over a few centimetres of ionised gas. These accelerated beams must be of sufficient quality to demonstrate exponential free-electron laser gain; achievable only through rigorous analysis of both the driver and witness beam's longitudinal phase space.
