The LANL Isotope Program irradiates a variety of targets using the 100-MeV proton beam at the Isotope Production Facility (IPF), followed by radiochemical separations to isolate the desired product. The program delivers hundreds of shipments of isotopes worldwide, primarily for medical applications, and conducts both fundamental and applied research at IPF. She is interested in production of novel isotopes for medical applications and supporting nuclear data experiments at IPF and through the production of required radioactive target materials.

Anna Llobet

Anna Llobet received her diploma in physics from Universitat Autonoma de Barcelona, Spain in 1996. She obtained her PhD Univ. Joseph Fourier (Grenoble-France) for her work at Laboratoire Louis Neel (Gre­noble, France) on the study of magnetotransport in spin polarized tunnel junctions for spintronics and by Univ. Autònoma de Barcelona (Spain) for her work performed at ICMAB (Institut de Ciencia de Materials de Barcelona, Spain) on the study phase segregation and charge ordering in manganites in 2000. This work involved using a large number of large user facilities like ILL, ESRF, LURE, ISIS, Saclay and the High Magnetic Field Laboratory in Tolouse using neutrons, x-rays and muons as well as large magnetic fields to characterize the properties of fully polarized spin tunnel junctions and the crystallography and magnetic order and magnetic field and temperature induced phase transitions and charge ordering in new compounds of the family AxB1-xMnO3.

Llobet joined MST-10 at Los Alamos as a postdoc in March 2001, working with John Sarrao and Wei Bao on the study of superconductivity and emergent behavior in correlated electron materials. She studied the interplay between magnetism and superconductivity on heavy fermion compounds of the family CeMIn5 and Ce2MIn8 (M=Rh, Ir, Co) by means of elastic and inelastic neutron scattering. In 2003 she joined the Lujan Neutron Scattering Center as the instrument scientist of HIPD (High Intensity Powder Diffractometer). In 2011 Llobet worked at Sigma and from 2012-2016, she was part of the management teams (acting deputy group leader) for Lujan Center, LANSCE Weapons Physics, and Neutron Science and Technology groups.

When she joined the Neutron Science and Technology group she started performing experiments at pRad in the field of dynamic behavior of materials (Rayleigh–Taylor instability, and Richtmyer–Meshkov instability) as well as contributing to the pRad user program organization. In the recent 2017 call for proposals, Llobet was PI or Co-PI in at least 6 proposals that spanned the fields of weapons physics, materials science, materials manufacturing, and qualification. Llobet envisions contributing to the expansion of the use of pRad to a broader range of phenomena related to materials science and weapons physics.

Norbert Seifert

Norbert Seifert (M’00-SM'04) is a principle engineer in the Technology and Manufacturing Group at Intel Corporation in Hillsboro, Oregon, where he manages a team of dedicated soft error experts responsible for test chip design, planning and conducting radiation test campaigns, modeling of radiation effects, and interacting with internal and external customers on radiation effects topics.

Seifert has over 20 years of experience in the semiconductor industry focusing on the interaction of radiation with matter at various levels throughout his career.  His PhD thesis (Vienna University of Technology, 1993) addressed the formation and dynamics of color centers in wide-bandgap crystals due to low energy electron, proton, synchrotron, and free-electron laser irradiation (research conducted mainly at Vanderbilt University, TN, USA). He worked as a postdoc at North Carolina State University (North Carolina, USA) characterizing charge transfer processes occurring in protons on rare-gas-atom collisions, and as a postdoc at Vienna University of Technology (Vienna, Austria) solving Navier Stokes equations for simulating droplet formations during laser irradiation of metallic surfaces.

From 1997 until 2001 Seifert had the great privilege of being educated and trained on the job in digital circuit design and computer architecture by technical leads in the Alpha Development Team at Digital Equipment Corporation (the team was acquired by Intel Corporation in 2001 and Seifert transferred to Intel in 2003).  Since 2001, Seifert has been investigating the impact of ionizing radiation on the data integrity of modern microprocessors, focusing particularly on radiation induced soft errors in logic data paths and clock networks.

Seifert has authored or co-authored over 60 conference and journal publications (of which more than 30 are related to the topic of soft errors), written one book on chip-level modeling strategies for soft errors and one book chapter on “Soft Error Resilient System Design through Error Correction.” Seifert has given several tutorials, invited talks, and keynotes on radiation effects at conferences and workshops. He holds four issued and one pending patents on radiation hardening at the circuit level.

In recent years, Seifert supported an effort lead by the Semiconductor Industry Association that impacted the U.S. Government export control policy (ITAR) to reduce inadvertent export controls on commercial electronics and was awarded the Intel Achievement award (Intel's Highest Award) for this work in 2014.

Seifert actively participated in the creation of several international industry standards on soft errors, such as JEDEC JESD89A, and is currently a member of the JESD89 Task Group working on the JESD89 revision to be called JESD89B. In his current role, Seifert regularly interacts with external industry representatives and technical experts at international conferences and work related meetings, where he is recognized as one of the leading radiation effects experts.

Over the years, Seifert has traveled numerous times to Los Alamos for radiation testing (LANSCE; ICE House 1 and 2). He not only enjoyed working there but also loves hiking in the area if time permits. One experiment Seifert likes to highlight in connection with Los Alamos, is the life testing experiment he conducted in 2010 at the Waste Isolation Pilot Plant (WIPP) in a small shack owned by LANL more than 2000 feet beneath the surface designed to shield devices from cosmic radiation. Traveling down the shaft to the experimental site is an experience Seifert will never forget.

Shigehiro Takajo

Shigehiro Takajo is a visiting research student at Los Alamos National Laboratory (LANL) and also a senior researcher at JFE Steel Corporation.

He studied physics at the University of Tokyo and received his BS in 2006 and MS in 2008. There he investigated the heavy electron pyrochlore compound and its ground states under extreme conditions such as low temperature using a dilution refrigerator (~10 mK) and high pressure using a cubic anvil apparatus (~8 GPa), and acquired fundamental experimental skills.

In 2008 he joined JFE Steel Corporation in Japan and engaged in the development of new mild steel sheets used for electrical appliances (-2010) and grain-oriented electrical steels used for transformers (2010-2016). He holds a number of patents in these research fields. During the developments he studied material science and learned how the conditions of manufacturing processes such as chemical compositions, cold rolling reduction rates, and annealing temperature affect the mechanical and magnetic properties of the steels. There what fascinated him most was the crystallographic texture, which was one of the most important factors of material quality and he also learned texture characterization method using EBSD and x-ray diffraction.

In October 2016, he joined LANL to acquire advanced knowledge about crystallographic texture as well as to build his scientific network. His current research interest is texture analysis using the neutron diffraction instrument HIPPO (High Pressure - Preferred Orientation) at LANSCE (Los Alamos Neutron Science Center) and he is pursuing PhD under supervision of Sven Vogel. His first work at LANSCE is to characterize crystallographic texture and phase of a gas-gun deformed stainless steel using HIPPO and EBSD with a collaboration of many researchers at LANL. The LANSCE User Group is an excellent platform to advance new knowledge of neutron facilities and promote a scientific collaboration, which is the reason why Takajo would like to become engaged as a representative.
