Entry  Mon Mar 23 14:12:54 2020, Ragan, Runs, E127 experiment stops,  
close file : run104 (14:12:44)
E127 experiment finishes on a successful note )) Congratulations to the entire team !!
Entry  Mon Mar 23 14:12:18 2020, E127 team, Runs, run entry - run103, scrapper is inserted,  
open file : run103
Scrapper is inserted
Entry  Mon Mar 23 14:02:07 2020, Ragan, Runs, run entry - run104, scrapper is removed,  

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)

Detector position (Si): -27 mm
GE01DD1IG position (Scraper): 9 mm

open file : run103
Scrapper was put back and than taken out again by miscommunication. run103 is made while using the scraper

With scraper, we have roughly 150-200 (p,g) counts now.

X-rays look fine!
