| Abstract | We have repeated some of our previous measurements of the intra-pixel response of the infrared detector arrays for the Fine Guidance Sensor (FGS) instrument on the James Webb Space Telescope (JWST). This set of tests was performed on a 5 micron cutoff substrate-removed HAWAII-1RG from the new batch of devices produced for JWST. The measurements were done at wavelengths from 650 nm to 1550 nm. The results from these tests indicate that there are no significant differences in the intra-pixel response between the older JWST devices and the new ones. Modeling suggests that the primary contributor to the response profile is diffusion in the bulk detector material. |
