Comments: 00:00 Raster not working quite right. Spent about 45 minutes trying to fix it & understanding why the lituium target data doesn't look "right". 00:46 Restarted taking data with C target @ uA. 01:40 changed to Li target (#5) asked for 2uA. 01:45 changed back to C target with recurrence of raster problem. 01:54 request change to "empty" to test raster problem vs. target position hypothesis. 03:50 After about 2 hours of study we have determined that the lithium target is inappropriately encoded. Resumed running with carbon target, 5uA beam current, 3x3 raster @ target 04:43 Switch targets to tantalum for Ta production running. 06:12 Changed to boron carbide target 06:44 Lowered beam current to 1uA.
