FOREWORD
The 14thLomonosov Conference on Elementary Particle Physics was heldat the Moscow State University (Moscow, Russia) on August 19-25, 2009 under thePatronage of the Rector of the Moscow State University Victor Sadovnichy.
The conference was organized by the Faculty of Physics and SkobeltsynInstitute of Nuclear Physics of the Moscow State University in cooperation with theInterregional Centre for Advanced Studies and supported by the Joint Institute forNuclear Research (Dubna), the Institute for Nuclear Research (Moscow), the BudkerInstitute of Nuclear Physics (Novosibirsk) and the Institute of Theoretical andExperimental Physics (Moscow). The Russian Foundation for Basic Research, theRussian Agency for Science and Innovation, the Russian Academy of Sciences, the
Dmitry Zimin "Dynasty" Foundation and the Russian Agency for Atomic Energysponsored the conference.
It was more than twenty years ago when the first of the series ofconferences (from 1993 called the "Lomonosov Conferences"), was held at theDepartment of Theoretical Physics of the Moscow State University (June 1983,Moscow). The second conference was held in Kishinev, Republic of Moldavia,USSR (May 1985).
After the four years break this series was resumed on a new conceptualbasis for the conference programme focus. During the preparation of the third
conference (that was held in Maykop, Russia, 1989) a desire to broaden theprogramme to include more general issues in particle physics became apparent.During the conference of the year 1992 held in Yaroslavl it was proposed by myselfand approved by numerous participants that these irregularly held meetings shouldbe transformed into regular events under the title "Lomonosov Conferences onElementary Particle Physics". Since then at subsequent meetings of this series awide variety of interesting things both in theory and experiment of particle physics,field theory, astrophysics, gravitation and cosmology were included into theprogrammes. It was also decided to enlarge the number of institutions that would
take part in preparation of future conferences.Mikhail Lomonosov (1711-1765), a brilliant Russian encyclopaedias of the
era of the Russian Empress Catherine the 2nd, was world renowned for hisdistinguished contributions in the fields of science and art. He also helped establishthe high school educational system in Russia. The Moscow State University wasfounded in 1755 based on his plan and initiative, and the University now bears thename of Lomonosov.
The 6thLomonosov Conference on Elementary Particle Physics (1993) andall of the subsequent conferences of this series were held at the Moscow State
University on each of the odd years. Publication of the volume "Particle Physics,Gauge Fields and Astrophysics" containing articles written on the basis ofpresentations at the 5th and 6th Lomonosov Conferences was supported by theAccademia Nazionale dei Lincei (Rome, 1994). Proceedings of the 7th and 8th
Lomonosov Conference (entitled "Problems of Fundamental Physics" and"Elementary Particle Physics") were published by the Interregional Centre for

STATUS OF THE ATLAS EXPERIMENT
P. S. Wells", on behalf of the ATLAS Collaboration
Dept. PH, CERN, CH-1211 Geneva 23, SWITZERLANDAbstract. The ATLAS experiment is a general purpose detector to observe proton-proton collisions at the Large Hadron Collider. The experiment has been commis-sioned with a large sample of cosmic ray events recorded in 2008 and 2009, andthe first proton-proton collisions were observed at the end of 2009. The very goodstate of readiness of the detector, and some first results of collisions, are reported.
1 Introduction
The ATLAS experiment [1] is a general purpose detector, designed to measurethe products of high energy proton-proton (pp) and heavy ion collisions fromthe Large Hadron Collider (LHC). The detector was built and is operated bya collaboration of about 2,800 physicists, including 800 PhD students, drawnfrom 169 institutions, coming from 37 countries, spanning 5 continents. Thispaper discusses the readiness of the ATLAS detector to observe LHC collisions,based on calibration work and studies of a large sample of cosmic ray events.
A total of 216 million cosmic ray events was collected in the autumn of2008, and a further 93 million in summer 2009. The overall event rate was
up to 700 Hz, but with less than 1 Hz passing through the pixel detectorat the centre of the experiment. In December 2009, about one million ppcollision interactions were recorded at the LHC injection energy, correspondingto 900 GeV in the centre-of-mass system. The beams were declared stablefor about 460 thousand of these collisions, and for these events the detectorcould be fully switched on. In addition, 34 thousand events were recorded at ahigher centre-of-mass energy of 2.36 TeV, but without the full tracking detectorat operational voltage.
2 The ATLAS detector
The overall apparatus is 25 m high, 44 m long, and weighs 7,000 tonnes. Acut-away diagramme is shown in Figure 1. The layout of the detector is drivenby the magnet systems, in particular the barrel and end-cap toroid magnets ofthe muon spectrometer.
2.1 The ATLAS magnets and the muon spectrometer
A 2.5 m long, 2.5 m diameter superconducting solenoid provides a uniform 2 Tfield for the inner detector, with an excitation current of 7.7 kA. The barrel andtwo end-cap toroids each have eight coils, with an excitation current of 20.5 kA.

Figure 1: Cut-away view
of
the ATLAS detector.
The
8 barrel coils are each
25
m long, 5 m wide and weigh 100 tonnes. The
typical field is 0.5 T. In contrast, each end-cap toroid has 8 coils in a common
cryostat
of 11 m diameter.
At
240 tonnes each, these were
the
heaviest indidual
pieces
to
be lowered into
the
ATLAS experimental cavern .
The
typical end-cap
field is 1 T. The full magnet system has
operated
reliably for long periods.
The
muon spectrometer provides a muon trigger and momentum measure
ment, with a momentum resolution better than 10% up to about 1 TeV. The
barrel toroid field alone covers
the
range
7
< 1.4, and
then
overlaps
the
end
cap field for 1.4 < 7 < 1.6. There are 700 precision chambers made from
monitored drift tubes (MDT) in the barrel , complemented by 600 resistive
plate
trigger chambers (RPC) for
