Academia Sinica firmó un contrato por un total de 40 detectores CMOS para usarse para las cámaras para el proyecto TAOS II.

August 7, 2012

TAOS II aims to measure the flux of more than 10000 stars at 20Hz or higher frequency to detect the diffraction pattern of occultations by KBOs. This could not be satisfied by using the traditional CCD technology commonly used in astronomical research.

After a significant effort to research all of the available options, the TAOS II collaboration has opted to use custom CMOS devices, each with an array of 1920 x 4608 16 micron pixels (31 x 74 mm), which will be produced by e2v. These back-illuminated, low read noise devices provide the capability to sample 1000 arbitrary small windows at a 20Hz readout rate while maintaining similar performance and sensitivity as normal scientific CCDs. The contract was approved by Academia Sinica on August 7, 2012.

Each camera will comprise a 2 x 5 array of these custom devices to cover the 154 mm viewable field. The first engineering device is expected to be delivered in December 2013, and all of the devices will be delivered by June 2015. The TAOS II cameras are scheduled to start observations in 2016.
