Abstract
This paper presents an overview of the electronics multi- array control system design that can control several different types of focal plane arrays simultaneously. This system is used with the SUBARU standard data acquisition system MESIA. MACS2 and MESSIA materialize a wide wavelength observation at visible and near IR wavelengths that requires different types of arrays. MACS2 consists of four types of cards. An isolation card is required for one imaging system. A clock driver card and an ADC card are required for an array, and a preamp card is required for an ADC card. Each card is daisy-chained through differential signals. Every array does not have to be placed closely, and no more signal lines are required even when controlling more than one array and type. The bias voltages to operate arrays and the offset voltage at the analog input can be controlled and monitored form a host workstation. We can arrange various environments to evaluate focal plane arrays without any modifications of printed circuit boards or any wiring. MACS2 is very useful and powerful for evaluating different types of arrays. Also we could save time to swap a spare card when a card for whichever detector is broken, and the maintenance of a recent complex imaging system becomes easier. MACS2 will be installed in TRISPEC, two InSb, WFCT, SIRIUS.
