OBSERVATIONS: 
Playing with degraders
Final degrader: 23mm
New BigRIPS run 238 started at 6:46 (38Mg beam attenuated by 1/8) -> very few counts in Si
New run 239-240 started at 7:03 (38Mg beam attenuated 1/2 narrow slit)-> we see more counts in the Si
run 241-242 atarted at 7:09 (38Mg 70% narrow slit)
run 243-244 at 7:16 (38Mg 5000enA)
run 245-246 at 7:23 (38Mg beam intensity 0.8)
run 247-248 at 7:32 (38Mg beam intensity 0.9)
run 249-250 at 7:38 (38Mg full beam)
run 251 at 7:41 (38Mg yield measurement)
