Experiments that we would want to do
Tests we want to do
Tape targets: high repetition rate solid targets
Build from Florian Condamine's target described for ELI Beamlines
Studying LMI with use of a back reflection diagnostic setup.
Many facilities have existing guidelines/requirements on target normal angles relative to lasers.
Ideas on looking at back reflection
Issue: Variability with target types and laser architecture
When doing multi-beam experiments, complicated by plasma conditions of target
Lots of past work on JLF in FI and SI campaigns, developing backscatter diagnostic packages
Control measurements looking at backscatter exist as well.
Existing jet experiments on TPW had calorimeter on leakage of transport mirrors. Used plasma mirrors
Combined Experiment with tape drive operating on TPW (rep rated not needed)-
see the size of the damaged spot;
exercise actually the tape target
Measure backscatter spectrum, energy and wavefront
Dresden performance target is a good example (gives expected proton energy and electron spectrum)
Define a standard target for MEC-U to have a comparison to TPW.
Include a detector designed for EMP resilience
Potentially look at water cooled beam dump system (see material degradation and thermal increase)
Experiments requiring high repetition rate.
LaserNetUS avenue
In practice, getting dedicated time on TPW through LaserNetUS for facility readiness could be a good proposal
Standard PRP? There may be avenues to go either through the call or direct.
Chandra's campaign: April 24 – May 26 - but probably delayed a few weeks
Conversation on money to SLAC for this is going to come next year
At CSU, which is over-subscribed, we will need to use a compelling
SLAC - Belfast - RAL MOU for development of high repetition rate targetry for EPAC
Target system with improvements to thermal stability over time (measured)
2 omega vs 1 omega short pulse experiments.
See if we can do the same physics at 2 omega as 1
Provide guidelines for MEC-U post-project directing towards 2 omega
targetry with jet
detectors (EMP / noise)
Cunningham, Eric Flint Previous chats about more laser-centric experiments. Laser diagnostics that could go at two different facilities
Methods to directly measure on-target intensity
Zeeman splitting in gas
Other papers in review - campaign at CLPU; others forwarded by Siegfried / Griffin
Pulse intensity contrast at full intensity when high repetition rate isn't available
