Project Title: Characterization and Optimization of a Mid-Infrared Astronomical Camera

Project Description:

One student is sought to assist in the characterization and optimization of an infrared camera which is used on the Hale 5-m telescope at Palomar and on the 3-m NASA Infrared Telescope Facility on Mauna Kea, Hawaii.

This camera is based on a 128 x 128 pixel, Si:As BIB array (sensitive to 5-28 micron radiation) and represents the state-of-the-art in astronomical imagers at these wavelengths. This camera is used to provide data on the atmospheres of the outer planets and to provide glimpses of stars at their very earliest stages of formation, as well as to provide followup, ground-based observations of sources discovered by the Infrared Astronomical Satellite which flew in the early 1980s.

The student will assist in the fine tuning and characterization of the system. Characterizing the camera will involve measuring its read noise, linearity, responsivity, capacity, uniformity, and photometric capabilities.

This position is most appropriate for astronomy/physics majors who are interested in astronomical instrumentation development. Familiarity with the Unix operating system, C programming, and data reduction software such as LabView, IDL, or IRAF is highly desirable and any previous experience with astronomical observation, system characterization, or electronic design is a plus. Electrical engineering students with an interest in astronomical instrumentation are also encouraged to apply. Due to restrictions on the detector technology, the student must be a U.S. citizen or permanent resident (with valid "green" card).

Background Information:

The student will work closely with me to characterize and optimize the instrument and to prepare it for upcoming observing runs at the Mt. Palomar 200" telescope and the NASA Infrared Telescope Facility this year. Non-Caltech students are welcome to apply, but ITAR restrictions on the detector require that they be US citizens or permanent residents. Please contact me via e-mail or by phone at the indicated number if further information is required.
