Stored Particles Atomic Physics Research Collaboration

SPARC India workshop, TIFR 2014

Download Schedule

The workshop is aimed at bringing together the leading researchers from our country in the accelerator based atomic collision physics and related fields. This meeting is to focus on the possible effort on a joint collaborative experiments using the Stored Particle Atomic Physics Research Collaboration (SPARC) / FAIR at GSI, Darmstadt Germany. Several colleagues from Europe are expected to join. In particular, we will explore the possible international collaborations between the SPARC, TIFR and other Indian groups. The SPARC collaboration is primarily responsible to organize the atomic physics experiments at the (FAIR) accelerator facility at Darmstadt, Germany. The existing ongoing research in the broad field of the accelerator based atomic physics across the country and that in GSI will be presented and a possible collaborative program may be discussed. Graduate student participation forms one of the key features of this workshop to provide them an exposure to the latest development in the field and glimpse of the possibilities in the future. Expected number of participents is 50.

The tentative list of topics to be covered,

Present atomic physics research in GSI, Darmstadt
Outline of the proposed FAIR facility and SPARC activity (HITRAP/CRYring etc)
Plasma Physics and Application related to GSI
Collisions between ions and atoms
Interaction slow and fast with solids, surfaces, clusters and bio-molecules
Electronic charge transfer, ionization and excitation
Accelerator techniques/instrumentation/detectors
Interaction slow and fast with solids, surfaces, clusters and bio-molecules
Strong Field physics and Ion-Matter Interaction
Advanced theoretical techniques in related fields of ion and electron collisions
Techniques of ion beam guiding and beam modification
Relativistic effects

The FAIR facility will give access to intense beams of slow, stored and cooled, highly charged, heavy ions of all species, that are accessible to ESR and thus yields an interesting research opportunity already now. In the light of the future FAIR project, one may even reasonably hope to access rare, unstable isotopes and most importantly anti-protons produced by all the new facilities, FAIR will bring.

In CRYRING@ESR a broad variety of experiments can be envisaged: in the fields of atomic collision and structure physics, for nuclear research at the Coulomb barrier, for studies of the intersection of atomic and nuclear physics, and for research with extracted ion beams, such as materials science or radio-biology. CRYRING is equipped with an interesting set of well regarded instrumentation, such as with a very cold electron beams facility, a gas jet target, a fast extraction to downstream experiments, and fast ramping capability. Moreover, with its RFQ injector beamline (300 keV/u, m/q = 4) we expect this machine to carry us through the extended shutdown periods necessary by the GSI/FAIR upgrades. Some future ideas for new instrumentation include an intense transverse electron target, cryogenic current comparators as highly sensitive current measurement device.

It may be pointed out that all working packages which were discussed during the meeting at the WHCI2012, TIFR are still valid. Examples are beam diagnostics (diamond detectors and read out electronics), x-ray, electron and recoil ion spectrometers etc. Please check the SPARC web page, as mentioned above
