ngVLA Lead Calibration Scientist (Open Rank) (4617)

Observatory Service and Science Socorro, New Mexico Charlottesville, Virginia Charlottesville, Virginia Albuquerque, New Mexico


Description

Position Description:

 

Position Summary

 

The National Radio Astronomy Observatory invites applications for a next-generation VLA (ngVLA) Lead Calibration Scientist. The preferred duty station will be in either the Array Operation Center in Socorro or the Albuquerque Office in NM, but the Central Development Laboratory or NRAO Headquarters in Charlottesville, Virginia may be a possibility. The successful applicant will work within the ngVLA project team, within the Science Support Integrated Project Team on detailed investigation of the calibration strategies and associated requirements for the ngVLA.

The position is initially available for 1 year with a target start date of no later than February 1, 2022.  Continuation of this position is contingent on progress and additional ngVLA project funding.  Funding for the successful applicant to attend and present at domestic and international meetings will be available.

Job Duties Summary

 

The successful candidate will be an essential part of the ngVLA effort as the project develops its Preliminary Design for consideration as an NSF Major Research Equipment and Facilities Construction candidate. The primary focus of this Scientist position will be leading the ngVLA calibration effort by developing the calibration strategy and associated requirements for the array in order to understand any implications for the hardware system architecture. Calibration strategies are required for phase/delay, gain, flux scale, polarization, and possibly other instrumental effects.

The calibration strategy will directly inform the system architecture and requirements. The study will include the derivation of associated hardware and software system requirements that support the selected calibration strategy. This study is expected to be carried out in close collaboration with the system engineering team, lead design engineers, and algorithmic development team at NRAO.  The appointee will also have time to carry out their own independent research. 

Essential Duties and Responsibilities:
 

The appointee will be expected to spend 75% of their time on duties directly related to calibration studies for the ngVLA. Those duties will include:

 

  • Evaluations of various calibration strategies to support the Level 1 System Requirements and identified Observing Modes.
  • Revision of the existing Calibration Requirements as necessary.
  • Develop the Environmental Monitoring System Concept and associated requirements to support tropospheric and ionospheric calibration.
  • Simulations of the effect of instrumental and atmospheric errors on the scientific performance of the array.Selection and documentation of calibration strategies for phase/delay, gain/amplitude, flux scale, and polarization.
  • Derivation of hardware system requirements to support the selected calibration strategies.
  • Act as a Local Organizing Committee (LOC) member for ngVLA Science Meetings.

 

The appointee will have the opportunity to use 25% of their time for their own independent research. Independent research for this position is strongly encouraged and should contribute to radio astronomy, NRAO and ngVLA futures.

 

Work Environment

 

Typical Office Environment.

 

Position Requirements:

 

Minimum Education
