EngagingtheDSexperimentalteamsearlierintheplanningphasehasresultedinimprovedshotreadiness

• At T-6 months, a set of slides containing high-level information about the experiment configuration are requested for all new DS experiments.

— The submitted information fosters communication between facility and the experimental team and allows the facility to plan follow-on work.

• A T-3 months, for new platforms, we have a target design review• We have also instituted a bi-weekly meeting dedicated to tracking and discussing open

issues for DS experiments.— This is very important between T-6 and T-3 months where consensus needs to be reached

on requirements for new capability, e.g. unique target gas fill.

DataSystems- TransitionStrategyBetweenCMT(old)andSST(new)shotsetuptools

§ Run both editors in parallel during transition (most of 2017)

§ Through periodic releases, migrate data groups from old to new editor• Start simple – a few stand-alone TD systems in initial releases (i.e.,

not the laser, not the DIMs)• Receive user feedback at earliest stages of implementation

§ A data group will be editable in only one editor at a time• Users will have access to a unified view of entire experiment from either

•  Low backgrounds: very low LPI from hohlraum, extremely low self emission!

!•  Compton cross section dominates for hν > 30keV!!

High density region formed by convergent shocks!

CR will provide the first direct measurement of density using X-rays!

HDC or CH “Gbar” sphere targets are good candidates !
