Title: Natalia Kuznetsova


1
High Energy Physics as a Career
Natalia Kuznetsova Fermi
National Accelerator Laboratory
  • I am a postdoctoral fellow in High Energy Physics
    at Fermilab
  • I am originally from Minsk, Belarus.
  • I got my B.A. in physics from Kenyon College, a
    small liberal arts school in central Ohio
  • In August 2001, I got my Ph. D. in high energy
    physics from the University of California, Santa
    Barbara
  • I came to Fermilab in September 2001.

2
What do I do?
  • I am a member of CDF collaboration
  • CDF Collider Detector at Fermilab

Asia
Total 11 countries 55 institutions 525
physicists
3
CDF Detector
  • We use the CDF detector to observe the results of
    very high energy proton-antiproton collisions
  • Because E mc2, the higher the energy of your
    colliding particles, the more "stuff" comes out
    of the collision.

4
What's inside a detector?
  • Different sub-detectors in a single particle
    detector are used for detecting and analyzing
    different types of particles

Results of proton-antiproton collision

What's a typical day like?
  • It's hard to describe a typical day -- what you
    get to do varies greatly, and there is a great
    deal of freedom to do whatever you want.
  • Typically, you are involved in three things
  • Maintaining some particular subsystem of the
    detector (hardware)
  • Writing code for analyzing the data (software)
  • And you get to learn LOTS of different computer
    languages!
  • Actually performing data analysis -- coming up
    with new ideas, etc..
  • Most people in HEP work long hours, but they do
    so by choice

7
Some things you might do on a typical day
Taking care of electronics
Taking detector shifts
Writing software
8
What is it like?
  • Because our experiments are so huge, it takes a
    lot of people to get things going
  • So you get to interact with lots of people --
    physicists and engineers
  • This has both good and bad sides

Future ATLAS Collaboration at CERN nearly 2,000
people!
9
Careers and salaries
  • If you would like to stay in academia and do
    basic research, the typical career progression
    is
  • grad student -gt postdoc -gt assistant professor
    -gt full professor
  • The level of responsibility and the amount of
    competition increases at each step

Occupation
Salary range
20k
(Doctoral) Grad. student
35-50k
Postdoc/Assistant professor
90k -gt
Full professor

Qualifications
  • To be a high energy physicist doing basic
    research, you need
  • Academically a Ph.D.
  • Personally
  • LOVE PHYSICS!! You are in this for the love and
    fun of the science, not money.
  • Be self-motivating, capable of learning new
    things on your ownr and fast, capable of
    collaborating with lots of other people, somewhat
    competitive, always curious

11
What else can you do with HEP training?
  • Because you get to do so many different things,
    you are well-prepared for non-academic careers
  • For example, your background in computer
    programming or designing electronics can be very
    valuable while applying for industry jobs
  • But the more important thing is, most people who
    have received HEP training can THINK.

What can you do to become a HEP physicist?
  • Apply to college with a good physics program.
  • Participate in a summer research program for
    undergraduates
  • Come to Fermilab for a field trip

SLAC Stanford Linear Accelerator Center
  • SLAC is located near the beautiful Stanford
    University campus, at Menlo Park in California
    (20 min. to the ocean).
  • The research performed at SLAC has been
    recognized with three Nobel Prizes in physics!
  • http//www.slac.stanford.edu is the first U.S.
    Web site!

The BaBar detector
BaBar looks at much lower Energy collisions than
CDF
17
The detector for BaBar I helped build
  • Many particles decay very close to where they
    were produced.
  • Thats why at the heart of many detectors is a
    device needed for finding just where this
    happened.
