Analysis of files for two more settings of F11 degrader to optimize implantation of 40Mg. + setting 1: from Nov 27th, 22:16 Fixed degrader: 3 mm Pb + 1 mm Al, Variable degrader: 1.3 mm W + 2 mm Al AIDA run: R26_0 to R26_38 BigRIPS run: 40Mg1037 (partial) to 40Mg1040 see attachments: run1038_imp*png + setting 2: from Nov 28th, 1:38. Entered F11 during stripper foil change and removed 1mm Al fixed degrader (same as during Nov 26th - ~ run 40Mg1012). Fixed degrader: 3 mm Pb, Variable degrader: 1.3 mm W + 2 mm Al AIDA run: R26_39 to ... BigRIPS run: from 40Mg1041 to ... see attachments: run104x_imp*png (2 hours of data: run 1041 and 1042) Setting 2 moved implantation depth one or two strips upstream (1.2 according to calculations). 40Mg seems to be implanted about the third strip; a conclusion with LOW STATISTICS, but consistent with the trend of how the implantation position depends on neutron number for the higher-count isotopes. Setting 2 seems to be our best option (at least without going into F11 and reconfiguring degraders). We will continue accumulating data with it. Attachments: the 1D plot shows the ion implant position (DSSD) gated for all ions and for Al and Mg gates in the PID. The 2D plots show the PID with gates on implants in different DSSDs.
