The Pan-STARRS Gigapixel Camera #1 and STARGRASP controller results and performance

The Pan-STARRS project has completed its first 1. 4 gigapixel mosaic focal plane CCD camera, Gigapixel Camera #1 (GPC1). The mosaic focal plane of 60 densely packed 4k×4k MITLL CCD Orthogonal Transfer Arrays (OTAs) constitutes the World's largest CCD camera. The camera represents an extremely cost and time efficient effort with a less than 18 month production and integration phase and an approximate cost of 4 million USD (excluding NRE). The controller electronics named STARGRASP was developed to handle the 480 outputs at near 1Mpixel/sec rates with Gigabit Ethernet interfaces and can be scaled to even larger focal planes. Sophisticated functionality was developed for guide readout and on-detector tip-tilt image compensation with selectable region logic for standby or active operation, high output count, close four side buttable packaging and deep depletion construction. We will discuss the performance achieved, on-sky results, design, tools developed, shortcomings and future plans.
