Unplugged TDC inputs for MCP front and back
To reduce the load on the VUPROM TDC, we unplugged
the TDC inputs for the front and back signals
of the MCP of the XUV detector.

more stability by bunching
Because the C3+ part of the ion beam is properly
bunched, it is no longer so sensitive to
the drifts caused by the e-cooler.

Laser Beam adjusted
The laser beam was adjusted in his position
to overlap better with the ions.

Analysis
fluorescence & energetic overlap
During the night shift we saw several rises
of the fluorescence (see another entry) and
also energetic overlap in coasting beam modus.
