Graduate Student ST 1
- Req. Number: IRC137431
- Organization : XCP-6/Plasma Theory and Applications
- City, State: Los Alamos, New Mexico
What You Will Do
The XCP-6: Plasma Theory and Applications group is seeking graduate student candidates who are interested in exploring and improving modeling methodologies for foams in high-energy-density systems. Traditional modeling approaches have often treated the foam as a homogenous material with a single equation-of-state and opacity, rather than a heterogeneous medium consisting of a combination of foam material and pores of various sizes. More recent developments in two-photon-polymerization have enabled production of lattice-type foams with bulk density on the order of 10-20 mg/cc, and the appropriate modeling approach is even less certain. Such low-density engineered foams are being pursued across a wide variety of applications including proposed inertial fusion energy targets.
This work would focus on improving the modeling of both traditional porous foams and engineered lattice foams using a radiation-hydrodynamics code with adaptive mesh refinement. Previous experimental datasets will be re-examined, and subsequent experiments will be designed as either planar, cylindrical, or spherical systems depending on diagnostic requirements. A particular focus will be post-processing the simulation results to create synthetic diagnostics and helping to set the diagnostic resolution limits that will be needed for these subsequent experiments.
What You Need
Project Description: Work to improve the modeling of both traditional and engineered-lattice foams in the high-energy-density environment.
Minimum Job Requirements:
Desired Qualifications:
Education:
Currently enrolled in an accredited graduate degree program in a science or engineering discipline with an overall GPA of 3.2 (out of 4.0) or higher. Must be enrolled in at least 6 semester credit hours (or full-time equivalent).
Work Location:
The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management
Note to Applicants:
Interested candidates should reach out to Radha Bahukutumbi at radha@lanl.gov
Due to federal restrictions contained in the current National Defense Authorization Act, citizens of the People's Republic of China, the Islamic Republic of Iran, the Democratic People's Republic of North Korea, and the Russian Federation, who are not Lawful Permanent Residents ("green card" holders) are prohibited from accessing facilities that support the mission, functions, and operations of national security laboratories and nuclear weapons production facilities, which includes Los Alamos National Laboratory.
Where You Will Work
Located in Northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security. LANL enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns. Our generous benefits package includes:
Directive 206.2 - Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States. Foreign nationals are subject to a similar requirement under DOE Order 142.3A.
No Clearance: Position does not require a security clearance. Selected candidates will be subject to drug testing and other pre-employment background checks.
New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.
Internal Applicants: Regular appointment employees who have served the required period of continuous service in their current position are eligible to apply for posted jobs throughout the Laboratory. If an employee has not served the required period of continuous service, they may only apply for Laboratory jobs with the documented approval of their Division Leader. Please refer to Policy Policy P701 for applicant eligibility requirements.
Incentive Compensation Program: For general program information refer to the Student Programs web page: https://www.lanl.gov/careers/career-options/student-internships/index.php
Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer. All employment practices are based on qualification and merit, without regard to protected categories such as race, color, national origin, ancestry, religion, age, sex, gender identity, sexual orientation, marital status or spousal affiliation, physical or mental disability, medical conditions, pregnancy, status as a protected veteran, genetic information, or citizenship within the limits imposed by applicable federal, state and local laws and regulations.
The Laboratory is also committed to making our workplace accessible to individuals with disabilities and will provide reasonable accommodations, upon request, for individuals to participate in the application and hiring process. To request a disability accommodation, email applyhelp@lanl.gov or call (505) 664-6947, opt. 3.
