L990926022:39:37Start of experiment52500
L990926122:42:32Incremented. forgot to turn on the chopper52500
L990926222:57:01Interupted for a few seconds to check sodium energy56840
L990926223:00:02Rayleigh HG adjusted56800
L990926223:59:34Sodium HG adjusted52380
L990926223:59:51Slight haze, does not impact to much52380
L990926201:02:46Sodium Convergence mirror adjusted40690
L990926201:02:51Rayleigh HG adjusted40690
L990926201:08:03Dye system tuned to 589.161 nm62150
L990926201:10:01Dye system tuned to 589.160 nm62380
L990926406:10:21Radar run done, doing some testing, incremented59590
L990927006:14:11removed beam expander59200
L990927006:16:12Yebs, a big increase in counts, had to do a lot of reconverging0
looks like the beam expander causes a beam direction change
L990927006:17:18Looks like I'm gonna need some info on beam expanders58970
The increase in counts was about times 4
L990927006:34:30Gonna close down the iris to see the impact on the sodium0
without the beam expander
L990927006:35:49The iris is 1/2 closed, slight impact seen , ups getting haze 0
probally the haze cauing this
L990927006:37:40closing iris fully0
L990927006:38:37Totally killed the sodium0
L990927006:38:53End of experiment54390
