open file : run101

beam: 124Xe54+
energy: 10 MeV/u

we run at MAX INTENSITY as we can: SIS was increased to its top, but unfortunately we still end up with 1.5e9 at injection from SIS. Sergey also optimized some stuff.

purpose: data with TARGET ON and SCRAPER OFF --> this leakage current spikes associated with primary scattering from the scraper edge seem to disappear, but we get still 10kHz rate on the detector a few sec after injection(this small "bump" 
after the peak in the Si current - see the picture below)
