CAELESTE CELEBRATES 5th anniversary with a visionary seminar! On Friday 17 June 2011, afternoon and
evening, Caeleste organizes a “visionary” seminar to celebrate
its 5th anniversary. The topic of
the seminar is “sensing and withstanding X-rays, gammas and heavy
particles”. The seminar takes place at the SAS Radisson Blu, Koningin Astridplein
7, Antwerp, across the main entrance of the Antwerp Central railway station. For program and
invitation: benoit@caeleste.be . |

8-11 June 2011 (Hakodate) |
Caeleste presents 2 papers at the
IISW, Hakodate, Japan. One is the
first report on “color X-ray” indirect photon counting, then other
is a report on the design of the “natural guide star” wavefront sensor. (see our publications page for the
papers) |

Caeleste demonstrates CMOS pixels that
are exceptionally radiation tolerant, beyond any other published result. These exhibit very low dark current
which does not measurably increase even after 50 kRad
TID by 60Co gamma. More… |

At the ISSCC, Caeleste presents the
X-ray irradiation results of the 16x16 pixel indirect X-ray photon counting
array. [publication…]

Caeleste’s X-ray photon counting
demonstrator array (see previous post) demonstrates photon counting under
70kVp X-ray illumination, both for direct detection (without scintillator) as
indirect detection (100µm sheet of GdOS). |

In an invited presentation at the OSA
symposium, Tucson, Bart presented the first Silicon results of its 16x16
pixel X-ray photon counting demonstrator array. More (the actual presentation pdf). |

Caeleste moves to new, larger offices at the Generaal
Capiaumontstraat 11, 2600 Berchem (Antwerpen), Belgium. It encompasses more office space, testing and characterization labs
and an rooftop observatory. |

Caeleste and SensL (of Cork, Ireland, www.sensl.com) present the first hybrid ADP (avalanche
photodiode) array, with both photon counting and distance ranging
capabilities. This
first-time-right designed linear array has 256 pixels, a distance range of
5000m (!) and a measured distance resolution of 150ps or 2cm. Development part
of an ESA program. Presented at
the CNES workshop, for the full presentation click here. |

8 Dec 2009 ( |
Caeleste and e2v (of Chelmsford, UK, www.e2v.com) present an image sensor with a
previously unseen combination of performance specs. The first-time-right design
demonstrates 2.5 noise electrons, 1000fps, column ADC, regional synchronous
shutter, 24um pixels with very high conversion gain, and is suitable for
backside illumination. Presented
at the CNES workshop, for the full presentation click here. |

Caeleste and Awaiba (of Madeira, Portugal)
announce a collaboration agreement to widen and leverage their design
capabilities and IP platforms. In the scope of this agreement AWAIBA focuses
on miniature sensors and packaging technologies for medical endoscopy, high
speed area and line scan applications and automotive high dynamic range
imaging, whereas CAELESTE focuses on X-ray and other medical imaging
applications, Space imaging (backside illuminated CMOS, hybrid image
sensors), single photon imaging (APD, X-ray),distance
ranging and time gating, and certain scientific imaging niches. |
