If there's one career area in which communications is a fine art form, it's in particle physics.

with as many as 2,000 other people on the same project. The project
members come from countries and universities around the world.
really more like running a large industry with one of these
experiments," says Douglas Beder, of the department of physics and
astronomy at the University of British Columbia (UBC). "Collabouration
between these people is intense."
The communication needs of these physicists was so intense that they invented the World Wide Web.
people who invented the World Wide Web on the Internet were the
physicists at Geneva, Switzerland," explains Beder. "They needed to be
able to talk to each other from around the world and transmit large
volumes of data to each other. The most demanding needs for
communications came out of the elementary particle experiments at these
group of these enormous projects, you'll find people whose main task is
to make sure the communication keeps functioning. If you have access to
the Internet, visit CERN's website to get an idea of the way this

Besides using Internet services, like e-mail and websites, physicists use video conferencing, says physicist Janis McKenna.
particle physics, we communicate a lot over video conferencing. It goes
over the telephone lines, with one phone line for the audio and one for
the video. Instead of flying over to Paris to present something to your
colleagues, they can ask you questions and you can answer back," says
McKenna. "It's just like being there."

Alto, California. At Stanford, she works with the SLAC program -- the
Stanford Linear Accelerator Center. (Not surprisingly, it's the home of
the first World Wide website in the U.S.)
are a particle physicist, and you've just been assigned to work on the
Large Hadron Collider (LHC) division at CERN. Devise strategies for
researching this division by: accessing CERN's website; obtaining
information from your library or a university physics program;
contacting CERN itself.
Gather and organize the information and put it together in a report form.
Include the following information in your report:
- What is the LHC?
- Where will the LHC be built?
- Briefly describe the history of CERN and where this projects fits in.
- Without going into detail, list the technological and theoretical challenges of the project.
- What are the LHC's hardware parameters?
- Who are the technical coordinators for the LHC project?

order to collabourate with colleagues from around the world, today's
scientists must be well versed in using the Internet as a
communications and research tool.
essential to understand data communications technology and know which
tools are most effective for which tasks. In addition, knowing how to
find information using different tools makes researchers more effective.
the World Wide Web is the most widely recognized Internet resource,
there are many other Internet applications. Using a good Internet or
computer dictionary, explain the uses and effectiveness of the
following tools. Indicate which are primarily communications tools and
which are primarily research tools.
FTP, Archie/Anarchie, Gopher
FINGER, WHOIS, X.500 Directory Service, Knowbot Information Service
Browsers (list 3 of the most commonly used)
Which of the above do you have access to at school? At home? At a community access center?
a list, including URLs, of all the Internet sites that deal with
particle physics. These sites should include FTP sites, Gopher sites,
TelNet sites, as well as WWW sites. For each site located, indicate
what tool was used and what key words you used in your search.

Solution to Practice
The information for this report was obtained through the LHC Section of CERN's website in October 1997.
The Large Hadron Collider (LHC) is an accelerator that will bring
protons into head-on collisions at higher energies than ever achieved
before. This will allow scientists to investigate further the structure
The LHC will be built on the Franco-Swiss border west of Geneva, Switzerland, at the foot of the Jura Mountains.
CERN was created in 1950s to enhance the cooperation between
scientists in different countries and, thus, forward front-line
research in Europe. CERN exists primarily to provide European
physicists with accelerators that meet research demands at the limits
of human knowledge.
The next research instrument in Europe's particle physics armory is
the LHC. It is designed to share the 27-kilometer LEP tunnel and be fed
by existing particle sources and pre-accelerators. The LHC will use the
most advanced superconducting magnet and accelerator technologies ever
employed. LHC experiments are being designed to look for theoretically
predicted phenomena. However, they must also be prepared for surprises,
which will require great ingenuity on the part of the physicists and
Three particular technological and theoretical challenges exist for this project:
- Superconducting magnets issues
- Large-scale cryogenics issues
- Accelerator physics issues
The LHC's hardware parameters are:
Injectors and transfer lines
Magnets for the ring
Powering and quench protection
RF and feedback
The technical coordinators for the LHC project are
