Home > Milestones Proposal Milestones
- New field of atomic physics with accelerators for Greece
- Extended highly charged ion capabilities of the Demokritos TANDEM
accelerator facility
- Setup of new state-of-the-art electron spectroscopy system
- New complete data base of systematic measurements of Auger spectra
from first row He-like ions
- Deeper understanding of the importance of cascade feeding of
metastable states in collisions of ions with gas targets
- Elucidation of mechanisms responsible in the non-statistical
production of excited three-electron states by electron capture
- Extension of new techniques to Be- and B-like metastable beams

Experimental Milestones to date

First Auger
spectrum (140728-164918) showing the KLL of C3+
ions formed by electron capture in colliisions of 12 MeV C4+
(1s2,1s2s 3S) + Ne (20mTorr) W=1525eV and F=4.
The big spot on the PSD is the 1s2s2p 4P line of C3+
while the next two lines are the 1s2s2p 2P-
and 1s2s2p 2P+. Slight misalignment of peaks
along the x-direction caused by insufficient mu-metal shielding between
gas cell and spectrometer. The individual projections along the x-direction
(energy dispersion axis) and the y-direction (focusing axis) are seen
on the right together with the signal from the sum of all 4 signals.
Only the 4P line is in the right place as most of
it decays closer to the HDA entry. Following this spectrum, more mu-metal
tubing was placed along the electron path within the beam line iself.

First
ion beam transmission test completed with
isolation valve closed, L45 dipoles on but L45 steerers off.
Measured 230nA in FC4 (before isolation valve) with 10 x 10
mm slits SL1 (after switcher but before the dipoles) and 400nA
in FC3 just before the switcher magnet. Beam: 1 MeV protons |
