| Run Plan
The purpose of this run is to continue the L-mode parameter scans began in MP586. This includes running very low density plasmas to look for the existence of a linear impurity confinement regime that is believed to be present below a nq value of approximately 4. Additionally, scans will be performed in kappa (1.0, 1.3, 1.8), Ip (.4,.6,.8,1.0 MA), and Bt (2.6, 3.9, 6.5 T ) to separate out their effects on the impurity confinement. Toroidal Fields: 2.6, 3.9, 5.2, and 6.5 T Plasma Current: .4 to 1.0 MA Working Gas: D2 Density: nl04 .2, .3 and .6e20 Boronization: None Equilibrium: USN, L-mode (1091202019 for equilibrium only) then modify from there.

| We managed to get all the way through the proposed run plan during the course of the day despite a number of hardware related difficulties. We were unable to use the RF at the low densities because they caused such a dramatic change in the density when on. Therefore the low density shots were often run as ohmic shots and at first glance it seems that there is no obvious drop in the impurity confinement time with decreasing density, even when below the linear/saturated boundary of nq~4. This will have to be examined in more detail but this is my initial observation. We moved on to the kappa/ip/bt scan and were able to get most of the cases proposed in the run plan. There was some difficulty at 2.6 T but 3.9 and 6.5 T operated much better. I abandoned all of the .4 MA cases because at such low current when operating with no RF power, the signal on the spectrometers of He-like Ca was too low for an useful data. A kappa scan was achieved which included typically values of approximately 1.15, 1.4 and 1.7. Some cases achieved slightly higher than 1.7 kappa but they often disrupted. After achieving the Bt scan/kappa/ip of the proposal, we moved back to normal field (5.4 T) to perform the same kappa/ip scan. Overall, despite a somewhat rocky start, a good deal of the desired cases were achieved and will be analyzed in more detail shortly. |

| Feb 17 2010 09:15:49:440AM | 1100217001 | Nathan Howard | Target for this shot is:
nl04=.2e20 RF steps from .7 sec every 200 ms, 1-4 MW Ip=.4 MA Bt=5.4 T ------------------------------------------------------------------------- 5 injections, see impurities entry for timing and details. Signal looks good on Hirex Jr. but no real RF. Although there seem to be problems with the RF data. |
| Feb 17 2010 09:56:35:097AM | 1100217001 | Nathan Howard | Due to the problems with the RF, it seems as though we might not be able to have any more RF for the rest of the day. We are going to proceed with ohmic shots at the same density and currents specified in the run plan but without the RF power steps |
| Feb 17 2010 10:22:25:940AM | 1100217002 | Nathan Howard | Target for this shot is:
nl04=.2e20 RF steps from .7 sec every 200 ms, 1-4 MW Ip=.6 MA Bt=5.4 T ------------------------------------------------------------------------- 5 injections, see impurities entry for timing and details. Signal for some of the shots looks good. There is a large injection of..(Mo?) about 1.3 seconds. We seem to have gotten the RF back at least in theory for this next shot so we are going to try again. |
| Feb 17 2010 10:37:22:580AM | 1100217003 | Nathan Howard | Target for this shot is:
nl04=.2e20 RF steps from .7 sec every 200 ms, 1-4 MW Ip=.8 MA Bt=5.4 T ------------------------------------------------------------------------- 5 injections, see impurities entry for timing and details. Signal for the last 4 injections looks good. There is a little bit of RF power although not close to the 4 MW due to the low density and current. Since things are a little behind, I am going to move on to the .3 nl04 shots. |
| Feb 17 2010 11:06:49:990AM | 1100217005 | Nathan Howard | Target for this shot is:

| Feb 17 2010 11:23:18:243AM | 1100217007 | Nathan Howard | Target for this shot is:
nl04=.2e20 Ohmic Ip=.6-.8 MA Rampdown at .9 sec Bt=5.4 T ------------------------------------------------------------------------- 4 injections, All look good. Another pretty good shot with a little bit of a decreasing density. It is in the range desired though. |
