HIGHLIGHTS
2013
Up to twenty-seven beamlines have been using the photon beams in 2013.
The installation of the FEMTOSLICING project, both outside and inside the storage
ring went without a hitch and the first equipment tests began in late 2013. The W164
wiggler, which will serve as "modulator" for this FEMTOSLICING operation and
as photon source for the PUMA beamline, was set up in October 2013. Two new
beamline front ends were installed for the future PUMA and ROCK beamlines. In
order to save space on the beamline, the first ROCK beamline mirror was positioned
in the beamline front end, inside the storage ring tunnel, which is very unusual.
In addition to the daily maintenance work, several heavy reliability actions are
underway, notably concerning the redesign of the Booster power supplies, the
storage ring magnet power supplies as well as the storage ring radiofrequency
system (cavity couplers, power amplifiers and cryogenic system).
Twenty-six very different types of insertion devices are now present in the storage
ring. Others are being designed or under construction, such as the U18 cryogenic
undulator for the ANATOMIX beamline, a spare U20 in-vacuum undulator for high
energy beamlines, a spare HU60 undulator for soft X-ray beamlines and two exotic
insertion devices in the context of the collaboration between SOLEIL and MAX IV:
an aperiodic WSV50 in-vacuum wiggler and a 3m-long U15 cryo-ready in-vacuum
undulator with a 3 mm minimum gap.
Among the R&D projects currently being undertaken in our division, the design
of a multipolar injection kicker, that allows injection without disturbing the stored
beam, is at an advanced stage. Its construction should begin in 2014 with an
installation in the MAX IV storage ring scheduled in 2015.
At the end of 2013, a know-how license agreement for the manufacture of RF solid
state amplifiers was signed between the company SIGMAPHI ELECTRONICS
and SOLEIL. This cutting-edge technology is a competitive, efficient, reliable and
effective alternative for providing a power source to radiofrequency cavities,
and was developed by SOLEIL’s "RF and Linac" group.
One of the priorities among the many objectives for 2014 is the commissioning with
beam of the FEMTOSLICING project and the fact that users of the CRISTAL beamline
will use radiation from this ultra-short electron bunch before the end of 2014.
Very stringent specifications on the stability of the position and size of the photon
beam for the NANOSCOPIUM beamline will be evaluated and additional resources
will be made available to meet them.
Also worth noting: the transition to a stored current of 500 mA with uniform filling
pattern will be offered to users in 2014.
Finally, feasibility studies will begin in order to optimize optics with an horizontal
emittance at least 10 times lower than the present one.
