Scaling and validation plans

RFX-mod Programme Workshop 2009 – 20-22 January 2009

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Data validation and scaling group mission

Optimization and validation of a reference RFX-mod database

Assessment of RFX scaling laws

Experiments and studies aiming at the comparison of global performance between RFP devices.

Localization of RFX-mod performance in fusion parameter space

Data validation and scaling group mission

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Rfx mod 2008 scalings examples

In most cases scaling are obtained from “private ” databases or build-up for a given project/conference:

(see i.e. Innocente RFP-WS08, PiovesanEPS08, LorenziniAPS08 …)

SHAx

QSHi

SH=

RFX-mod 2008 scalings: examples

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Work in progress pulse file versions

Aims: databases or build-up for a given project/conference:

pulse file with validated data

possibility of modifications (calculated data and calibrations, new data) and traceability

modified pulse files will work in the same way of the original ones

a procedure has been developed to trace modifications to pulse files, in order to guarantee that derived quantities are aligned with modifications

the new procedure allows retrieving and displaying of older versions.

versions of data are identified by their insertion dates (MDSPlus feature)

A specific database of modifications will support the pulse file versions management and traceability

Work in progress : pulse file versions

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Pulse file modifications next steps

Some databases or build-up for a given project/conference: details for the version creation are going to be completed (i.e. operational procedure (useradministrator), routines documentation in progress,...)

commissioning steps to be defined:

Commissioning of the procedure on a limited and agreed number of shots

first campaign for pulse file updating ...

useful tools in progress with the aim of a better and easier usableness

web visualization of the modifications and easy comparison with the original signals

web access of Traverser

a general presentation of the pulse file modification procedure will be organized soon (specific comments from users)

pulse file modifications: next steps

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Pohm estimate

An example of possible application of the new tool provided by the pulse file version is given by the estimate of the confinement parameter.

work is in progress in order to evaluate such modifications:

Include the measured Te profile in the calculation of the poloidal beta

study of transients can play a major role in the present RFX-mod operations (i.e. QSH transition …).Time evolution of confinement parameter estimate would be useful and work is in progress on

the account for time evolution of pressure profiles

evaluation of pohm with improved time resolution

Pohm estimate

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Summary database

Public database: automatic daily procedure for adding data in the various tables from the pulse file

Default not validated data

Some tables are manually filled (ex. ‘confinement’, ’spectroscopy’…)

Summary database documentation:

available on intranet page http://intranet.igi.cnr.it/servizi_tecnici/servizio_calcolo/software/Dblib/dblib.htm

Self documented tables through routines (IDL, …)

Useful tool: the validation procedure should be extended (see next slides)

Summary database

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Rfx mod plasma parameters explored in 2008
RFX-mod plasma parameters explored in 2008 in the various tables from the pulse file

Average parameters in the flat-top (source: summary database)

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Future plans proposals documentation

update of documentation of the online post processing programs

a documentation of control algorithms is proposed

pulsefile (version traceability, routines, web tools…)

Encourage the easy and accessible description of diagnostics

Future plans/proposals: documentation

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Data validation proposals

cross-validation programs, comparison of same parameter from different diagnostics:

ne (TS, Interferometer,GPI,probes), Te (in different radial position)...

Validation status: flags on signals/data (default unchecked)

in order to obtain a database of marked shots (with checked and useful data)

avoiding duplication of validation procedure

Data validation proposals

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Future plans proposals database collection

Verification of the programsexisting database and not covered regions

Selected shots for a continuous database

highlight of suitable shots periodically (for example each week)

several information for a limited number of shots

Including a subset of validated parameters

Selection of important parameters, i.e. for confinement estimate  several diagnostics and people have to be involved (including also the same information from different diagnostics)

Parameter set including ex. profiles, tomographic reconstruction, magnetic boundary information...

Times: time average on given time window, trigger events (significant time instants), ex. confinement estimate during transients…)

Proposal of periodic scan series at the state of art of the discharge performance and setting up

Future plans/proposals: database collection

Main aim:

selected good RFX pulsesunder given condition and fully diagnosed

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Database development and maintenance

Verification of the programsexisting database

periodic scan series at the state of art

database development and maintenance

continuous database

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Future plans proposals scaling

Scaling for perspectives of RFX/RFP (projections) programs

Scaling on selected particular states detected in RFX-mod (QSH, SHAx …)

Comparison between different configurations obtained in RFX-mod (RFP, tokamak, ULq)

Comparison with others RFPs (MST, Extrap-T2R, RELAX)

Future plans/proposals: scaling

RFX-mod Programme Workshop 2009 – 20-22 January 2009


Conclusion

Proposals from DV&SG programs

Documentation

Database development and maintenance

Scalings

We invite the researcher team to collaborate in order to achieve such goals

Suggestions are welcome
