Instrument testing

WFC3 has undergone several iterations of fully integrated instrument testing. This testing took place at Goddard Space Flight Center (GSFC). During thermal vacuum (TV) testing, reference file data are collected and the instrument is characterized and calibrated. The first two TV sessions took place in the winter of 2004 and spring of 2007. TV3 testing is scheduled for early spring of 2008. The links below connect to pages giving the results from the various TV campaigns.

(Up to date calibration information is located in Howard Bushouse's Calibration Plan webpage. This page contains links to the science calibration test plan, SMS spreadsheets, and other associated documentation.)

TV3 Results

Spring 2008. This testing exercised both UVIS and IR flight detectors, and was used to collect data for the initial reference files.

TV3 testing took place in February and March of 2008. Both flight detectors were installed in the instrument.

TV2 Results

Summer 2007. TV2 was performed with backup UVIS and IR detectors in place.

TV2 testing used a backup UVIS detector (build 2), and a backup IR detector (FPA129).

TV1 Results

Winter 2004. WFC3's first TV test was performed with the flight UVIS detector and a backup IR detector in place.

TV1 testing used the flight UVIS detector (build 1), but a backup IR detector (FPA64).

Below is a list of ISRs supplying TV1 test results.

Mini-Ambient Results

Just prior to TV1 testing, WFC3 underwent a limited set of tests with the instrument under ambient conditions. We referred to this testing as "mini-ambient".

UVIS Detector Oddities found during mini-ambient

This page gives examples of WFC3 detector characteristics noted prior to ambient testing. Examples of each type of behavior, along with links to any relevent ISRs, are provided below.
