Summary of Brho1 and Brho2 optimizations for the 37Ca beam.

Attachment 1:
Results of the Brho1 scan. Corresponding LISE run numbers are also shown in the figure.
As the beam intensity was fluctuating, the counting rates were normalized with respect to the intensity.
By changing Brho1, we tried to search for the peak of the 37Ca production. The yield seemed to reach the maximum at around 2.10 Tm,
although sometimes the rates were not reproducible (see the data point of the run 306, for example). 

Attachment 2, 3:
Changes of the yield and purity by scanning Brho2. The shaded area corresponds to the width of the slit (shown only for 0%).
They were well optimized at about 1.925 Tm.
