New measurement:
Start: About 00:12
Stop: About 00:43
LMDfile: 229ThFirstTest7775.lmd-229ThFirstTest7776.lmd
First tries to see the bunched ions with full test experiment circle and detectors.
Bunching visible in xuv-anode, sa_sz, PMT-south, PMT-north.
Bunches seem to be very wide, possible wrong revolution frequency set in the DAQ.
PD NO doesn't see the laser, screen prop. still in front of the window.
7e8 ions in the SIS
Standard XUV-settings
Several DAQ crashes and errors 
New measurement:
Start: About 02:00
Stop: About 02:30
LMDfile: 229ThFirstTest7780.lmd
Same test with new freq: 3.90415MHZ and without screen.
Nice Bunches in particle detector. Broad bunches in detectors.
Errors in DAQ
PD not working correctly or laser wrongly setup.
4.3e8 ions in the SIS
Standard XUV-settings |
