I am a dedicated Physicist with a
strong background in theoretical and
experimental physics, specializing in
areas such as quantum mechanics,
particle physics, and low temperature
physics. Demonstrated ability to
conduct complex research, analyze
data, and draw accurate conclusions.
Skilled in mathematical modeling,
computer simulations, and
problem-solving. Experienced in
collaborating with multidisciplinary
teams to achieve research goals and
contribute to scientific advancements.
Seeking to leverage my expertise and
passion for physics to make
significant contributions to
innovative projects and further expand
knowledge in the field. There are my
latest achievements:
·
**Designed a vertical septum magnet
for the APS-U** I intruded a novel
concept to cancel the leakage field of
a vertical septum magnet and designed
the DC septum magnet for the Advanced
Photon Source Upgrade (APS-U) project.
We have built the septum magnet and
measured its field and found that the
septum magnet cancels any leakage
field.
·
**I introduced an advanced design
structure to the hybrid permanent
magnet (HPPM) undulators for the
APS-U** I introduced some design skill
sets for optimizing the field
roll-off, increasing the field, and
minimizing the demagnetization field,
allowing the narrowing down of the
pole width to reduce the magnetic
force of HPPM undulators. With the
design skill sets, all the HPPM
undulators below that I designed for
the APS-U have an advanced compact
design structure which improves its
performance and reduces the material
cost of the HPPM undulators by 30%.
·
**Designed APU-U 28-mm period
undulator** I designed a 28 mm period
HPPM undulator for the APS-U with an
advanced compact structure that
provides an effective field of 8308 G
at a gap of 8.5 mm with a reduced
magnetic force of 30%. The measured
effective field at the same gap was
9750 G, 4% higher than the design. The
devices were either easy to tune or
did not need to tune due to the
reduced force structure of the design.
Also, the measured phase error was 2-3
deg between the open and closed gaps,
the smallest phase error measured at
the APS.
·
**Designed APU-U 25-mm period
undulator.** I designed a 25 mm period
HPPM undulator for the APS-U with an
advanced compact structure that
provides an effective field of 8308 G
at a gap of 8.5 mm with a reduced
magnetic force of 30%. The measured
effective field at the same gap was
8600 G, 4% higher than the design. The
devices were either easy to tune or
did not need to tune due to the
reduced force structure of the design.
Also, the measured phase error was 2-3
deg between the open and closed gaps.
·
**Designed APU-U 21-mm period
undulator.** I designed a 21 mm period
HPPM undulator for the APS-U with an
advanced compact structure that
provides an effective field of 6674 G
at a gap of 8.5 mm with a reduced
magnetic force of 30%. The measured
effective field at the same gap was
7150 G, 7% higher than the design. The
devices were either easy to tune or
did not need to tune due to the
reduced force structure of the design.
Also, the measured phase error was 2-3
deg between the open and closed gaps.
·
**Designed APU-U 13.5-mm period
undulator.** I designed a 13.5 mm
period HPPM undulator for the APS-U
with an advanced compact structure
that provides an effective field of
3105 G at a gap of 8.5 mm with a
reduced magnetic force of 30%. The
measured effective field at the same
gap was 3172 G, 2% higher than the
design. The devices were either easy
to tune or did not need to tune due to
the reduced force structure of the
design. Also, the measured phase error
was 2-3 deg between the open and
closed gaps.
·
**Designed APS 14-mm period
undulator.** Designed a 14 mm period
HPPM undulator for the dynamic
compression sector of the current APS,
with an advanced compact structure
that provides an effective field of
3,364 G at a gap of 8.5 mm with a
reduced magnetic force of 30%. The
measured effective field at the same
gap was 3504 G, 4% higher than the
design. Also, the measured phase error
was 0.5 - 1 deg between the open and
closed gaps.
