The 11th NLTE Code Comparison Workshop

Advanced collisional-radiative (CR) models are extensively used in plasma
spectroscopy to analyze plasma kinetics and spectra produced far from local
thermodynamic equilibrium (LTE). Non-LTE atomic models also play a critical role
in radiation-hydrodynamic simulations used to help design plasma experiments. It
is therefore not surprising that verification and validation (V&V) of these
complex CR models are of significant interest. Since experimental benchmarks for
validation are extremely challenging, computational experiments and comparisons
are one of the primary tools for V&V of CR codes. The NLTE Workshops aim at
development of such tools and techniques.

Important!
Similar to the previous workshops,
a necessary and sufficient condition for participation would be to submit at least one calculated case. A detailed description of the cases and format requirements can be found in the
Call for Submissions. Please contact Yuri Ralchenko (yralchen at nist.gov) for details on file uploads.
UPDATES
THIS SITE WILL BE DOWN OCT 26-27 2019 due to the planned maintenance.
The requests/comments below are generally optional but following them would highly facilitate comparisons.
Oct 23:
- The Call for Submissions contains new information (marked in yellow).
- all Kr cases: assume that the plasma consists of deuterium (D) gas with Kr added at 0.01% atomic fraction. To a very good approximation, the D is completely ionized with a number density matching the specified electron density, while the Kr ion density is 1.e-4 of the D number density.
-VH case: use radii of (1.e-4, 0.01) cm instead of (0., 0.01) cm. Data in the spectrum section for these cases -- including the bonus case -- should have units J/s/cm2/eV.
Oct 22:
- KrF case: please use 10-eV resolution for instrumental broadening.
- Ge case: Matching the spectra may require accounting for an instrumental resolution of 4 eV (fwhm).
Oct 21:
- For cases which require emission and absorption spectra, the emission spectra should be labeled spectrum (or spectrum1 and spectrum2) while the absorption spectra should be labeled absorption (or absorption1 and absorption2).
- VH case: Matching the spectra will require accounting for an instrumental resolution of 10-12 eV (FWHM).
Oct 10:
- We request not one but two (GeF1 and GeF2) cases to match the two available experimental spectra.
Registration
The registration fee for the workshop will be 100 Euro to cover some food services. The details on the fee payment will be added here soon.
There will be no registration fee due to the generous contribution of the LLNL High Energy Density Science Center.
It would also be very helpful if you inform the organizers on your intention to participate in this Workshop.

Location, accommodation, etc.
The meeting will be held at the
Hotel Fataga. The rooms can already be booked using a promo code
ULPGC. You will get a 12% discount when booking online only at the hotel website and for stays between November 3 and November 10. The final room rate is expected to be about 100 € (including breakfast). These reduced rates (and the code) will be on until
September 30, but will depend on availability.
We plan an informal reception on the night of Sun Nov 3 and a dinner on Wed Nov 6.
Computer Equipment
We will have an Internet connection at the meeting room and (probably) a dedicated wireless
network for the Workshop purposes.
