Universities Help on NuMI|
This article is the third in a series that will focus on the benefits
of Fermilab/University collaboration on different accelerator projects.

Small neutrino experiments such as NuMI have a close integration between
the accelerators and detectors, offering physicists and students a complete
perspective of the overall experiment. For example, a group of students
from the University of Texas designed and built a system to monitor the
tertiary muon beam produced along with the neutrinos for MINOS.
"It's a great learning experience for the students," said Sacha Kopp,
Assistant Professor at the University of Texas and supervisor for the project.
"This kind of hands-on experience is good training and gets students more
strongly connected with their experiments. It's also a good introduction for
those students who eventually decide to do an accelerator PhD thesis."
The University of Texas group also built a system of segmented Secondary
Emission Monitors (SEMs) to monitor the 120 GeV proton beam extracted from
the Main Injector to the NuMI target. "The foil SEMs monitor the proton
beam profile onto the target. They must withstand much higher instantaneous
beam power than previous instruments, making this an interesting challenge,"
Kopp said. "We hope these might be of use elsewhere."
Bruce Baller, Fermilab's NuMI Department head, said universities often create
new technology for Fermilab. "While Fermilab has to focus on keeping the
machines operating, universities can build new machines that you can't just
buy from a vendor," he said. "With any new machine, however, there is a risk
involved, which requires even more caution because these new machines affect
not just one but many of the experiments going on."
Also contributing to the NuMI beam monitors were the University of Wisconsin
and University of Pittsburgh for the muon monitor R&D, Indiana University for the
beam Monte Carlo, UNICAMP/Sao Paolo and Argonne National Laboratory for the
target hall instrumentation, and Brookhaven National Laboratory for the
beam instrumentation readout.

So Long, Bob Johanek|
Bob Johanek retires today after working at the Fermilab Technical Division
for over 16 years. He has worked as a CNC Machinist in the Village Machine Shop,
making components that go in nearly all the projects at Fermilab. Before he
worked at Fermilab, he worked as a tool and dime maker for 25 years.
"Although it will be nice to retire, I'll still miss all the camaraderie with
the guys and getting all the local gossip," he said. "It's something you've
done all your life, and now you'll never do it anymore, so it'll be a change."
Johanek said that he plans to spend more time working in his garden at his
Warrenville home with his wife, as well as going fishing.
Tuesday's story on Jim Gunn of SDSS winning the AAS Henry Norris Russell
Lectureship omitted the name of Jerry Ostriker, another significant early
member of SDSS and the Russell Lectureship winner in 1980. Fermilab Today

BLOGS: A Year in a Physicist's Life
Einstein's unkempt appearance was likely essential to his adoption as a
pop icon, argues David Waller of the Sudbury Neutrino Observatory in
Canada, who suggests that physicists commemorate Einstein by growing big hair.
Directing a beam of protons to a detector 1000 meters away reminds Debbie Harris
of Fermilab in Illinois of giving birth, because both processes have to occur
in stages. These are highlights from Quantum Diaries, a new project sponsored
by a coalition of particle physics labs to commemorate 2005's World Year of
Physics. More than 20 physicists from around the world will chronicle their
opinions, interests, successes, and failures over the next 12 months with
regular dispatches, video clips, and photos. So far, participants have
weighed in on everything from how they got started in the field to the
connection between physics and jazz.

Antigravity has feet of clay
by Philip Ball
Could astronauts take a leaf out of H. G. Wells's book The First Men in the Moon, and use spacecraft propelled by antigravity devices? Some see the idea as science fiction, but major space agencies take it seriously.
In 2001, the European Space Agency (ESA) commissioned two scientists to evaluate schemes for gravity control. They have concluded that, even if such control were possible, the benefits for lifting spacecraft out of the Earth's gravitational field would probably not be worth the effort1.
