Abstract: (IOP)
We present a new instrument composed of a large number of
sub-electron noise Skipper-CCDs operated with a two stage analog
multiplexed readout scheme suitable for scaling to thousands of
channels. New, thick, 1.35 Mpix sensors, from a new foundry, are
glued into a Multi-Chip Module (MCM) printed circuit board on a
ceramic substrate which has 16 sensors each. The instrument, that
can hold up-to 16 MCMs, a total of 256 Skipper-CCD sensors (called a
Super-Module with ≈ 130 grams of active mass and
346 Mpix), is part of the R&D effort of the OSCURA experiment
which will have ≈ 94 super-modules. Experimental results
with 10 MCMs and 160 Skipper-CCDs sensors are presented in this
paper. This is already the largest ever built instrument with single
electron sensitivity CCDs using nondestructive readout, both, in
terms of active mass and number of channels.Note:
