Performance evolution and expectations management: lessons from Tevatron and other machines
Below we review the LHC luminosity progress in 2010, discuss the luminosity
evolution of the Tevatron collider at different stages of the Collider Runs,
emphasize general dynamics of the process, compare with the performance of the
other colliders analyze planned and delivered luminosity integrals, and discuss
the expectation management lessons.Comment: 4 pp. Chamonix 2011 LHC Performance Workshop, 24-28 Jan 2011:

Crystal Ball: On the Future High Energy Colliders
High energy particle colliders have been in the forefront of particle physics
for more than three decades. At present the near term US, European and
international strategies of the particle physics community are centered on full
exploitation of the physics potential of the Large Hadron Collider (LHC)
through its high-luminosity upgrade (HL-LHC). A number of next generation
collider facilities have been proposed and are currently under consideration
for the medium- and far-future of the accelerator-based high energy physics. In
this paper we offer a uniform approach to evaluation of various accelerators
based on the feasibility of their energy reach, performance reach and cost
range. We briefly review such post-LHC options as linear e+e- colliders in
Japan (ILC) or at CERN (CLIC), muon collider, and circular lepton or hadron
colliders in China (CepC/SppC) and Europe (FCC). We conclude with a look into
ultimate energy reach accelerators based on plasmas and crystals, and some
perspectives for the far future of accelerator-based particle physics.Comment: 8 pp. The European Physical Society Conference on High Energy

Reflections on the nature of genius: on the 300th anniversary of Mikhail Lomonosov (1711-1765)
This presentation goes beyond celebratory narration of the life and
scientific achievements of Russia's first modern scientist Mikhail Vasilievich
Lomonosov (1711-1765). Coming from the notion of complexity of sciences, we
introduce "a genius formula" G=TBD for semi-qualitative evaluation of a
person's impact on the society, distinguish two type of geniuses, give several
examples and draw general conclusions. The work largely follows presentation at
the Fermilab Colloquium in November of 2011.Comment: 4 p
Space-charge compensation experiments at IOTA ring
Space-charge effects belong to the category of the most long-standing issues
in beam physics, and even today, after several decades of very active
exploration and development of counter-measures, they still pose the most
profound limitations on performance of high intensity proton accelerators. We
briefly consider past experience in active compensation of these effects and
present in detail the progress towards experimental studies of novel schemes of
space-charge compensation at the Fermilab's IOTA ring.Comment: 5 p
Summary of session 3 on synchrotron radiation and beam dynamics
Below we summarize presentations, discussions and general conclusions of the
Workshop session on "Beam Dynamics Issues". Major subjects include effects due
to synchrotron radiation (SR), cryogenic loads, electron cloud, impedances,
intra-beam scattering (IBS) and beam-beam interactions.Comment: 2 pp. EuCARD HE-LHC10 AccNet mini-workshop on a High-Energy LHC,
