NSTX Physics Operations Course Navigation (Mueller) Jan 26-28, 2010

Plasma Control System

2

• The following slides illustrate how to get into the PCS, find control items and edit parameters

• If you signed up to the course, your login has been changed to load modules needed to run the PCS user interface to operate of a future shot file

• You have not been added to the group which would allow you to edit the NEXT shot or to stop and start the PCS

• The PCS system can be reached only from 3 terminals in the control room and from PCS developers stations which have the proper firewall permissions


Course Outline

3

•Log into Mac as yourself•Ssh to pcs-srv-2

•ssh –Y –l yourusername pcs-srv-2•Get gup back•Type “uif”


Start editing future shot file(next shot is really the file for the next shot)

4

•Select future shot

•Enter name for file•apply

•Startup view•Category: Discharge shape•Phase: Shot start


•Restore from MDSplus archine•Enter shot number•Load all categories will setup everything like this shot (well almost everything)•RF power and timing, CS gas pressure must be requested•NBI setup does not exist for most past shots and must be dealt with


Warnings appear upon the restorejust dismiss

7


Basically redundant informationjust dismiss, everything else will be like restored shot

•What you get from select data to load


•Category:Discharge Shape,• Phase: Control•Sub gives this list

•Selecting Coil currents gives next page


•Selecting a coil displays that coil programming kA/Ip(MA)

•Red cross hairs can be used with left mouse button to expand display like so…


•You can edit single points by typing, selecting and replacing, or deleting and adding

•After editing you must apply to make the changes take effect

•New point

•Deleted point

•Select add-drag and use the middle mouse button


•Clicking on select allows multiple points to be selected with left mouse button•Click Edit gets a drop-down menu for standard cut and paste to clipboard•Selecting adjust vertices opens box

•After making changes you must either cancel or apply them before


•The switch from the discharge shape category to isoflux is controlled by the system category separately for each PF coil•The handoff is made smoothly by ramping the isoflux output request up while ramping the discharge shape output request down Vout=S*Viso +(1-S)*Vds

•Ramp time ~30 ms


•The equilibrium category must start calculating before the isoflux feedback is turned on

•Waveform steps to new value at time entered


•To select which signals are used in the rtEFIT analysis


•Primary sequence in isoflux category •Note, since sys waveforms are 0 until 70 ms, the innerwall phase is not actually used


•Target shape at .07s


•This is under subset Discharge Shape•Edit Rp using adjust vertices•Rp is offset from basis shape rather than Rp value


•Saves shape to plot later (1 deep) in red

•Turning this on displays committed shape in red

•Update Targets applies the discharge shape and displays the new shape in black


Use this as a guide

24

•You can log into pcs-srv-2 from one of 3 control room Macs

NSTXMAC16NSTXMAC15NSTXMAC28

•Start the user interface gui (uif)

•Make future shot with any name you like

•Restore a shot setup from MDSplus (or a future shot you made)

•Navigate through the categories, sequences, phases, and subsets to see what is available

•Practice using editing features
