ITEP history

Institute for Theoretical and Experimental Physics

was founded on December 1, 1945.

the heavy-water reactor was run in 1949

in 1961 the 7-GeV proton synchrotron started operating.

It was the first Russian proton accelerator using the strong focusing principle.

(small prototype of the biggest Russian 76-GeV machine built later in Protvino).

Now ITEP is Russian scientific centers aimed at studying nuclear physics

and physics of elementary particles.

Institute occupies the area of the old eighteenth century estate "Cheremushki".

ITEP research program• Theoretical study of the properties and interactions of elementary

particles and atomic nuclei and astrophysical aspects;

• Study of hadron-hadron and hadron-nuclear interactions and resonance systems;

• Investigation of fundamental interactions using colliding beams and high-energy accelerators;

• Study of electroweak interaction at accelerators and low-background facilities;

• Investigation of low-energy interactions;

• Solid-state physics, physical chemistry and superconductivity;

• Nuclear fusion at powerful heavy-ion and electromagnetic drivers;

• Development of new proton therapy methods and construction of a positron-electron tomograph for medical diagnostics;

• Development of new methods of proton and heavy-ion acceleration;

• Development of a new generation of safe nuclear-power facilities;

DC04 Summary

Quite visible participation in ALICE and LHCb DCs

ALICE → ~5% contribution (ITEP part ~70%)

LHCb → ~5% contribution (ITEP part ~70%)

With only 64 CPUs

Observed problems reported to colleagues in collaborations

More attention to LCG now

Distributed analysis – very different pattern of work load

connectivity with CERN and TIER1 centers is an issue !

Advertising GRID ideas

• Russian VO PHOTON for SELEX colleagues was organized in 2005 (Dolgolenko)

• Regional centre for AMS (VO in preparation)

• Collaboration with CBM project (GSI, Darmstadt)

• ITEP theory department is very interested

ITEP physicists are starting to use LCG resources for their every day work.

LHCb group has performed simulations of light collection efficiency in LCG (~20K jobs finished in 2 days)

Plans for the nearest future

Further support of LHC experiments Data Challenges

Increase significantly the power of ITEP farm in 2006

becomes a trivial task running automatically

special computing facility is organized in ITEP

current installation occupies only ~5%

Concentrate on distributed analysis (test GANGA)

connectivity with CERN and TIER1 centers is an issue !
