Status of the Trans-Neptunian Automated Occultation Survey (TAOS II)

TAOS II will aim to detect occultations of stars by small (~1 km) objects in the Kuiper Belt and beyond. Such events are extremely rare (<0.001 events per star per year) and short in duration (~200 ms), so many stars must be monitored at a high readout cadence in order to have a significant event detection rate. TAOS II will operate three 1.3 meter telescopes ad the San Pedro Martir Observatory in Baja California, Mexico. With 2.3 sq. deg. fields of view and high-speed cameras comprising CMOS imagers, the survey will monitor as many as 10,000 stars simultaneously with all three telescopes at a readout cadence of 20 Hz. Progress on the development of the survey infrastructure was significantly delayed by COVID due the the facts that the observatory was closed for more than a year and that supply chain issues delayed the completion of the cameras. However, the cameras have now been installed, and the final stages of the commissioning of the survey are now underway. This poster will provide an update on the status of the survey infrastructure development and plans for the operation of the survey.
