Title	365: Lithium dropper commissioning and ELM modification
Name:	Gary Jackson jackson@fusion.gat.com	Affiliation:	General Atomics
Research Area:	General Physics	Presentation time:	Not requested
Co-Author(s):	C. Chrobak	ITPA Joint Experiment :	No
Description:	Commission the lithium dropper on DIII-D and evaluate the effect of lithium on ELMs	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:	In the startup phase of DIII-D in FY13, during beam conditioning, drop lithium and check out the functioning of the lithium dropper. As a secondary goal, look for any changes in edge conditions. This is the first part of MP2012-94-02
Background:	The lithium dropper has been tested in the DIII-D lab and will be ready for installation on DIII-D before startup.
Resource Requirements:	lithium dropper. To mitigate any concern about window contamination the amount of lithium during startup will be less than 0.4 gm, which was the total of all lithium previously injected using the DIII-D lithium pellet injector (no adverse effects were noted in the past).
Diagnostic Requirements:	density, magnetics, filterscopes, zeff array, bolometer, Thomson and CER if shutters have been opened
Analysis Requirements:
Other Requirements:	This is listed as an ROF proposal (not just commissioning), because we expect to obtain some data on the effect of lithium on the plasma edge parameters.
