Working Group 1
9:00-11:00 Short presentations on topics influencing stability, e.g. stability of the driver (laser and particle beam), injection mechanisms (internal and external), witness beam requirements, synchronisation and plasma targets and density profiles. Presentations are intended to raise awareness of specific issues influencing the stability and guide the general discussion on how to enhance it.
11:00-11:30 Wrap up results of the previous discussion.
-
Working Group 2: Post-Plasma Beam-Quality Preservation
9:00-10:00 Short (~10 mins) presentations on current activities from the different projects in the context of the working group scope.
Presentations:
FLASHForward (Vladyslav Libov, Timon Mehrling)
LUX (Andi Meier)
REGAE (Klaus Floettmann)
HYBRIDS (Thomas Heinemann)
PITZ (Gaurav Pathak, Martin Khojoyan)We will relate people's studies to one or more of the subtopics, note their challenges in this topic, the status of their studies and the aim of their studies.
10:00-11:00 Discussing and formulating a common plan on how to achieve the preservation of the beam quality.
11:00-11:30 Finding overlap in points of interest and agreeing on future collaborations and activities.
-
Working Group 3: Extreme Beams
LWFA
- What are the limits for the energy gain?
- Overcoming/extending dephasing and depletion limits
- Review injection techniques: How can we generate the most extreme beams in terms of charge, emittance, energy spread, etc?
- External.
- Wavebreaking.
- DDR.
- Ionization-induced.
- New ideas:
- Resonant addition of laser drivers.
- Plasma wakefield excitation by incoherent laser pulses.PWFA
- What are the limits for the energy gain?
- Driver depletion, head-erosion
- Review injection techniques: Which one can generate the most extreme beams in terms of charge, emittance, energy spread, etc?
- External.
- Wavebreaking?.
- DDR.
- Ionization-induced:
- Self-induced: Beam and Wakefield triggered.
- Assisted: Trojan Horse.
