Team #Night | General | Scraper Tests Ion / Laser Beam | laser is 4-6mm below the ion beam.
It could be that the interaction between
both beams came only from the interaction |

Team | General | strange XUV Anode signal | We see a strange behavior of the anode signal
when we bunch the ion beam and electron cooler
is on.

Sebastian | General | "new" laser wavelength | Minor changes in electron cooler voltage (~+13V,
now 66903V measured by DMM) leads to that
we had to shift the laser wavelength to:

of 9.038946 MHz. This is 7 times f_rev (see
previous post).

today at 2 PM. The new revolution frequency
is now 1.291278 MHz. |

Danyal | DAQ | 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.
