Description
ESO and JRA2 OPTICON have funded e2v technologies to develop a compact
packaged Peltier cooled 24 μm square 240x240 pixels split frame
transfer 8-output back-illuminated L3Vision CCD3, L3Vision CCD for
Adaptive Optic Wave Front Sensor (AO WFS) applications. The device is
designed to achieve sub-electron read noise at frame rates from 25 Hz to
1,500 Hz and dark current lower than 0.01 e-/pixel/frame. The
development has many unique features. To obtain high frame rates,
multi-output EMCCD gain registers and metal buttressing of row clock
lines are used. The baseline device is built in standard silicon. In
addition, a split wafer run has enabled two speculative variants to be
built; deep depletion silicon devices to improve red response and
devices with an electronic shutter to extend use to Rayleigh and Pulsed
Laser Guide Star applications. These are all firsts for L3Vision CCDs.
The designs of the CCD and Peltier package have passed their reviews and
fabrication has begun. This paper will describe the progress to date,
the requirements and the design of the CCD and compact Peltier package,
technology trade-offs, schedule and proposed test plan. High readout
speed, low noise and compactness (requirement to fit in confined spaces)
provide special challenges to ESO's AO variant of its NGC, New General
detector Controller to drive this CCD. This paper will describe progress
made on the design of the controller to meet these special needs.
