EN Groups: STI
The Sources, Targets and Interactions Group will have as
common ground the study of beam interactions with matter, aiming to apply its
know-how to particle generation (ISOLDE Radioactive beam sources, CLIC
photoinjectors and polarized e+ e- sources), and to particle interception
(collimators, absorbers and dumps). The Group is in charge of the conceptual
design, production, operation and maintenance of devices in the LHC injectors
and the LHC machine (sources, targets, collimators, dumps etc…) as well as in
the secondary beams. The group is responsible for developing and maintaining the
FLUKA Monte Carlo code and for providing formal training and support to its
users in the accelerator community and to the experiments worldwide. The group
hosts the nTOF users and is a member of the collaboration, participating to the
nTOF experiments to include the experimental data in the cross-section databases
for FLUKA. Maintains a top level expertise and promotes studies in neutronics
and neutron based systems (spallation targets, ADS etc.).
The group will be formed of five sections:
This section is responsible for the operation of low level
controls and equipment instrumentation (motors, sensors etc…) for all the
equipment under the group’s responsibility. Writes and maintains all the FESA
classes and expert application programs for accelerator operation, develops
radiation-hard motors and sensors, precision electronics compatible with long
cables and with high immunity to Electromagnetic Interference. Develops and
maintains high voltage fast (~psec) switching electronics and fast acquisitions
for use with the RILIS and CTF3 lasers.The section provides design and technical
support for the RADMON hardware and software. The section provides first-line
contact for interventions on the objects in the accelerators.
The section coordinates the FLUKA team and is in charge of
the FLUKA code development, maintenance and support. Provides studies on energy
deposition, beam interaction with machine elements and FLUKA simulations for the
accelerators and different applications (i.e. medical). Participates to the
conceptual design of machine components, in collaboration with the other
sections of the group. Participates in the nTOF experiment. Coordinates the
Single Event Upset task force (R2E) and radiation tests to electronics for the
accelerator community, and supports the accelerator equipment groups in the
interpretation of the test results. Hosts the project leader of RADMON.
The section is in charge of laser based particle sources, in
particular the RILIS (Resonance Ionisation Laser Ion Source) and the
photoinjectors of CTF3. It maintains a high-level know-how on high power pulsed
lasers, and on development of photocathodes for high charge and high brightness
photoinjectors. The section participates to the international effort to develop
a polarized positron source for the CLIC study. It also participates to european
and international networks for R&D on new materials and laser technology for
applications to particle sources.
RBS: Radioactive Beams Sources
The section is responsible for providing the targets for the
generation of radioactive ion beams for the ISOLDE facility. It maintains the
technical competence on low (~3 kW) and medium (~100 kW) power targets for
ISOLDE and the High intensity upgrade of ISOLDE, and provides the scientific
know-how for the development of new solid and liquid targets and ion sources. It
is responsible for the technical coordination of the ISOLDE experimental area,
for the AD target area and hosts the HIE-ISOLDE Project leader.
TCD: Targets, Collimators and Dumps
The section is in charge of all the beam intercepting devices
in the CERN accelerators and secondary beam lines. The section provides know-how
for the conceptual design, operation and maintenance of the mechanical part of
the objects, and develops the necessary mechatronics in collaboration with the
ECE section. The section carries out expert interventions in the tunnel in case
of mechanical failure of the objects. The section is also responsible for
studies on High-energy (~MWs) targets for future facilities (Eurisol, ESS etc.)
and maintains the expertise in the field of structural material behavior under
extreme conditions (liquid metal targets, jets, sprays, etc…).
