Low-Level Radio Frequency Engineering Technologist (Engineering Technologist 3 or 4)

Due to federal restrictions contained in the current National Defense Authorization Act, citizens of the People's Republic of China-including the special administrative regions of Hong Kong and Macau-as well as citizens of the Islamic Republic of Iran, the Democratic People's Republic of Korea (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. The LLRF team works on ultra stable frequency sources, solid-state and vacuum tube based amplifiers, temperature controlled coaxial lines spanning the length of the accelerator, electronics detecting the beam amplitude at the injector, resonance control systems compensating for cavity changes due to RF heating and fast electronics meant to prevent a cavity arc from damaging amplifiers producing megawatts of power.

What You Will Do

This position will be filled at either the Job Title Lower/Higher level, depending on the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.

The Accelerator Operations and Technology Division (AOT), Radio Frequency Engineering (RFE) group is seeking an Engineering Technologist 3 or 4 for the Low-Level Radio-Frequency (LLRF) team.

The AOT division maintains, operates, and upgrades all accelerator systems used at the Los Alamos Neutron Science Center (LANSCE) complex. These consist of two 750-keV Cockcroft-Walton-based injector systems (H+ and H- systems), a 201.25-MHz drift-tube linear accelerator (LINAC) utilizing high-power diacrode tubes, an 805-MHz coupled cavity LINAC utilizing high-power klystrons as the primary power source, a proton storage ring, and roughly a kilometer of beam transport lines that deliver beam to the five independent research programs. The RFE group is principally responsible for all radio frequency (RF) systems and their associated amplitude and phase control in relation to the accelerating beam.

Due to the different types of equipment that we are involved with, when working in AOT-RFE no day is the same as the next. Members of the LLRF team are involved in the design, construction, testing and installation of high-frequency electronics and software systems dedicated to the control of RF waveforms to achieve optimal acceleration and bunching of the beam. The LLRF team works on ultra stable frequency sources, solid-state and vacuum tube based amplifiers, temperature controlled coaxial lines spanning the length of the accelerator, electronics detecting the beam amplitude at the injector, resonance control systems compensating for cavity changes due to RF heating and fast electronics meant to prevent a cavity arc from damaging amplifiers producing megawatts of power.

Engineering Technologist 3 ($106,400 - $176,000)
The Low-Level Radio Frequency (LLRF) team at LANSCE is looking for a candidate with a background in Electronic Systems or related field to join the RF Engineering group. This is a support role with dynamic responsibilities, guided by the priorities of the High-Power Radio Frequency (HPRF) plant and RF controls required for the LANSCE Modernization Project (LAMP). Duties include troubleshooting programmatic equipment and extending to engineering and supervisory aspects of project execution, such as performing initial calculations, developing specifications, submitting procurement orders, and coordinating testing, delivery and installation.
The successful candidate will be a member of the Low-Level RF Team and will support the development and implementation of digital control systems. This work includes the development, testing and troubleshooting of custom analog, digital and RF printed circuit boards (PCBs), as well as testing code in LabVIEW or MATLAB for these systems. Close collaboration and coordination with other technologists, technicians and engineers on the LLRF team along with cooperation across other accelerator systems groups (such as software, instrumentation and accelerator physics) is expected.
Engineering Technologist 4 ($117,200 - $195,400)
In addition to what was outlined at the lower level, at this level the successful candidate will independently lead the execution of low-level RF systems projects as a part of LAMP. This includes providing technical expertise and guidance on RF controls as well as offering both technical and operational guidance to LLRF technicians and engineers during installation, integration and operation of RF control systems.
