Advancements in the P48 MOSAIC Camera for Transient Discovery at Palomar

The P48 MOSAIC camera is set to enhance the capabilities of transient discovery at Palomar Observatory. Innovations include a new wide-field visible imager, an improved data analysis pipeline at IPAC, and a dedicated photometer machine (P60). Developments focus on increasing readout speed, re-leveling the focal plane, and upgrading the thermal control system. Key features include a field-flattening entrance window, automated shutter, and focal plane metrology. The requirements document is complete, and major procurements are underway, targeting first light in November 2008.
