An accomplished, self motivated, and versatile physics technician with a
strong background in computers,
development, computer security, lasers, high intensity flash x-ray systems, analog
electronics, optics, particle accelerators, digital imaging, and diagnostics
development for the
Los Alamos National Laboratory.
Jan retired on July 1, 2003 after almost 40 years with the laboratory.
July, 2003 to Present
Since retirement on July 1, 2003 Jan has been happily de-stressing from an
important but stressful position at Los Alamos National Laboratory where he worked most recently in the stockpile stewardship (nuclear weapons) program.
De-stressing activities were based on
outdoor activities with friends, and
playing as often as possible with computers.
October, 2001 to
X-ray Imaging Liaison and Development for Atlas
. Acted as the primary
P-22 contact and liaison with Bechtel Nevada for the development of a fast,
four frame, digital imaging camera system for the Atlas pulsed power
machine. After development, participated on the Atlas axial
radiography diagnostic team for a variety of weapons physics experiments.
June, 1998 to
Flash X-ray Production Activities. Responsible for all
details of reverse engineering the "Plattsflash" x-ray system. This
resulted in the construction and fielding of 13 complete systems, which
have now been fielded on several dozen experiments. This activity required
extensive interactions with Bechtel Nevada, in which he was P-22's primary
X-ray Experiments in Support of Weapons Physics. Fielded, or helped field many flash x-ray systems at Pegasus, Shiva Star, Atlas, the Ancho Canyon Gas Gun, several local explosive sites, and U1a at NTS. These experiments often involved P-22 CCD imaging. Acted as primary contact for x-ray production activities associated with the Thoroughbred and Cimaron sub-critical events. Earned a 1998 Los Alamos Achievement Program (Physics Division) award for "dedicated performance in support of complex issues related to the Laboratory's U1a (Cimarron) event."
Selected as a member of a a small internal committee to determine the next Physics Division director. Susan Seestrom was selected for the position in part due to his diligence. Susan later became the head of the Weapons Physics Directorate, and later still the Associate Director for Experimental Physical Sciences.
1996 to June, 1998
Pegasus Interferometric Target Diagnostic.
Responsible for the construction and fielding of a 94 GHz interferometer
on the Pegasus II Pulsed Power Facility
at LANL. This device was used to
visualize the implosion and subsequent expansion of the Pegasus target.
ITS Interferometric Beam Size Diagnostic. Member of two man experimental
team charged with the development of a non-intercepting beam size
measurement for possible use at DARHT
. The team designed, built, and deployed a
94 GHz interferometer system and a unique "spinning wheel" calibrator the front-end of DARHT. All field work was performed at the Integrated Test Stand.
Earned a 1999 Los Alamos Awards Program honor "in appreciation of your exceptional commitment to teamwork for the DARHT Phase I design and
1995 to February, 1996
Portable High Intensity Laser System. Member
of a two man team charged with the construction and fielding of a unique,
high-intensity, portable Ti:Sapphire laser system. This ultra-fast light
source was to be used as part of a diagnostic tool to evaluate explosively
detonated devices. When finished, this laser was to be housed in the back
of a truck for enhanced portability. Funding was lost after successful
June, 1994 to
EUV LINAC. Responsible for beam line construction
coordination, and diagnostic development and fabrication for a high
intensity linear electron accelerator (LINAC), to be used for the
generation of extreme ultra-violet (EUV) radiation. Began fielding the
experimental gas cell, and associated diagnostics. Earned a 1994 LANL
Distinguished Performance Award "In appreciation for your contribution on
the Subpicosecond High Brightness Accelerator."
1989 to June, 1994
P-1, Bright Source Laser. Member of the
experimental team for an ultra-high intensity UV laser. Responsibilities
included fielding, building, modifying, and operating high-tech diagnostic
instruments, such as X-ray and visible streak cameras, spectrometers, and
Operation Desert Storm. Volunteer member of a small
team of scientists who developed, built, and fielded, in just two months,
a unique long-range LIDAR system for the detection of biological weapons.
Also, participated in all Arizona airborne tests. Awarded a 1990
Distinguished Performance Project Team Award "In appreciation for your
contribution on the LIDAR Project Team."
May, 1985 to
P-14, Forge Laser. Operated, modified, and
maintained a 20 joule, 100 pSec, glass laser system and target chamber to
permit characterization of a series of X-ray streak cameras. Responsible
for all day-to-day activities at the facility, as well as most of the
July, 1983 to
P-14, Antares Laser. Fielded the primary low-energy X-ray
diagnostic on the Antares target chamber. Developed a 1 GHz multi-channel
analog and digital recording system based on NTS instrumentation. Recorded
all shot data, and digitally processed all results.
July, 1982 to
AT-5, NEST Portable Linear Accelerator. Project leader
of a one million dollar portable linear accelerator for use by the Nuclear
Emergency Search Team. Responsible for all purchasing, scheduling,
packaging, and team member supervision. Unable to bring project to
completion due to funding difficulties out of his control.
May, 1981 to
P-14, Under-ground Experiments. Developed a 100 MHz,
low-noise, high-linearity, analog fiber optic receiver for NTS
under-ground experiments. This unit became the prototype for EG&G's
to May, 1981
MP-1, Analog Circuit Design Consultant. Provided
analog circuit design consulting and prototype production for visitors and
experimentalists at LAMPF (now named LANSCE
). Fielded designs included spark-chamber
readouts, delay-line TAC's and TDC's, high-speed amplifiers, high-voltage
regulators, and photo-multiplier bases and discriminators.
June, 1972 to
MP-1, Beam Line Diagnostic's. Designed the
electronics for most of LAMPF's beam line diagnostics. Designs included
various beam current monitors, beam profile monitors, fast wire scanners,
and beam position monitors. These same modules were often used in the
experimental areas as well.
1965 to June, 1972
MP-3, RF Structures. Characterized a variety of
RF structures in the main LAMPF beam line. Measured such parameters as Q,
resonant frequency, temperature drift, and radiation damage; helped
design, and build instruments to automate these measurements and tune the
