Subject: Discussion for 37Ca 
Offline analysis of LISE run0281. F31 = +/-0.6 mm, without wedge.
The number of counts of 37Ca was 900/50 = 18 times larger than 36Ca.
Comparing this result with a LISE++ simulation, if the Brho setting is optimized for 37Ca,
we expect to gain 12 x 4 = 48 times higher beam intensity.
Considering that the EPAX parametrization tends to over predict production cross-sections of neutron-deficient
exotic nuclei, the prediction for the 37Ca yield would be more reliable than 36Ca.
A rough estimate of the beam intensity is shown below.

36Ca 1.5 pps (100 nA, +/-6 mm) -> 37Ca 100 pps (100 nA, +/-6 mm) -> 37Ca 16 kpps (4 uA, +/-24 mm)
