Hyper Suprime-Cam: CCD readout electronics
2008
Hyper Suprime-Cam is planned to employ about 120 2k×4k fully-depleted CCDs with 4 signal outputs for each. The data size of an image becomes larger than 2Gbytes. All of the CCDs are designed to be readout parallel within 20 seconds, and the readout noise is expected to be 5e. The frontend electronics will be mounted in a vacuumed
cryostat, and connected to the backend electronics mounted on the outside of the
cryostat. The frontend electronics includes entire analog circuits for CCD including CCD drivers,
preamplifiersand ADC. The backend electronics consists of newly developed
gigabit Ethernetmodules combined with 2Gbytes
memory modules, and several supporting boards. We will present the current status of the CCD readout electronics developments for HSC.
