Open Date: December 9, 2021 Close Date: March 7, 2022 We Are The Accelerator Research Department of Fermilab’s
Accelerator Division seeks highly qualified candidates for a position of Associate
Scientist focusing on beam-cooling technology. Fermilab is America’s premier laboratory for particle
physics and accelerator research, funded by the U.S. Department of
Energy. We support discovery science experiments in Illinois and South
Dakota and at locations around the world, including Canada, mountaintops in
Arizona and Chile, and the South Pole. Fermilab is an established, world leader in beam-cooling
R&D and has initiated a new research program dedicated to the development
of Optical Stochastic Cooling (OSC). The central purpose of this program is a
multiple order-of-magnitude advance in the state of the art for particle-beam
cooling and control. In the high-intensity beams of modern accelerators, the
ability to increase or maintain beam density and lifetime is essential.
Historically, this has required the development and application of a variety of
beam-cooling concepts and technologies to facilitate particle accumulation,
higher luminosity and to counteract diffusive (heating) effects, such as
intrabeam scattering, Touschek scattering and residual-gas scattering. One of
the greatest conceptual and technological triumphs in this area was Van der
Meer’s Nobel-Prize-winning Stochastic Cooling. Extension of the stochastic
cooling principle to optical frequencies and bandwidths could increase
achievable cooling rates by three to four orders of magnitude. The world’s first demonstration of OSC at Fermilab’s
Integrable Optics Test Accelerator (IOTA) was achieved in 2021. The next phase
of this research includes the complete demonstration of an operational optical
stochastic cooling system with >1000x optical-power gain and an additional
~60x increase in the density of transverse sensing and feedback. This will
include an experimental program, which makes use of the IOTA ring, along with a
set of complementary simulations. The OSC system will also be combined with
methods in machine/reinforcement learning to establish new capabilities in
advanced beam control. Associate Scientist conducts directed research, develops
theories, and devises methods to apply laws, theories and research in physics
projects related to the overall mission of the Laboratory. The position is for
a period of three (3) years, with the potential for extension, pending
additional funding. The appointees are judged to have the potential to make
contributions to the Laboratory that will subsequently qualify them for
appointment as Scientist, a scientific appointment without term. You Will
