Obtaining Access to PPPL's TRANSP data

• Access to TRANSP input and output data is granted to individuals for known hosts.
• Access to Non-PPPL data may require additional authorization by the appropriate management.
• To request access
  • for non-restricted runs, send email stating your user name, host name and the type of data you wish to access to: cludescher@pppl.gov
  • for JET runs, return the signed JET Access Request.

Getting Started

• Define MDSplus environment variables
  on PPPL unix cluster:
  
  
  • On "portal" and SGI

          After you have loaded a compiler:
           module load nstx 
           module load ntcc 
    

• Connect to / open a run
  for PPPL you need to provide:
  • Server Name = transpgrid.pppl.gov
    For PPPL supported Tools:
    • Tree Name = transp
    • Tokamak Name (e.g.: NSTX)
    • Shot Year (e.g.: 03)
    • Run Id (e.g.: 111370A01)
    For Other Software:
    • Tree Name = transp_<tok> (e.g.: transp_nstx)
    • Pulse Number = translated Run Id (e.g.: 1113700101)
  
  for MIT you need to provide:
  • Server Name = cmoda.psfc.mit.edu
  • Tree Name (e.g.: transp01)
  • Pulse Number (e.g.: 960116024)

Tools for accessing TRANSP data

TRANSP Namelists:

Extracting a text node from MDSplus:

mds_get_inf - menu driven Utility to retrieve any text node from a MDSplus TRANSP Tree, e.g.:

     Name_List        Contents (TF.PLN file)
     Ufile Names      Comment

RPLOT:

the traditional TRANSP interactive plotting post-processor
On the unix cluster, rplot is in $NTCCHOME/bin.
RPLOT is availabe as a NTCC Module

UGRAF%:

to view Ufiles

   select: OPTION M
   N < Ufile Lable > e.g. CUR 
  
   If TRANSP or BEAST Tree:
   ------------------------
   P .INPUTS
   select sub Option X to enter < RunId> (and < TOK.YR> for TRANSP)
   Note: you also have to enter the shot number.

TRXPL:

convert a TRANSP equilibrium timeslice into G-EQDSK format.

IDL

To read Ufiles from IDL, see Ufile read/write library routines.

PPPL e.g.:

TRANSP runs are on the MDSplus Server on TRANSPGRID.

sts=pppl_transp_open('108918A20', 'NSTX', 02, force=1)
Note: You may now also use mdsopen.
e.g. to open NSTX.02 108918A20 : mdsconnect, 'transpgrid.pppl.gov' mdsopen,'transp_nstx',1089180120


CMOD e.g.: mdsconnect, 'cmoda.psfc.mit.edu' mdsopen,'transp01', 960116024
See IDL example for details.

Fortran callable library

See Fortran examples for details.

TRAVERSER

Define the environment < tree >_path = < server >:

e.g.: m3d_path      atlas.gat.com::
      transp01_path cmod2.psfc.mit.edu::
