^{16}N^{7+}[190 MeV] from^{15}N^{7+}[192.4 MeV]**scale factor = 1.1366/1.1086 = 1.025**

- [Oct 19]

- Expected calculated rates for tuning (
**acceptable - ideal**):- At EXIT Detector:
**> pps/pnA**(midplane slits set to ~+-4 mm, ~3% momentum acceptance). - At HELIOS Cross Detector:
**> pps/pnA**(assumes ~25% transmission, maybe on the high side...)

- At EXIT Detector:
