Ocam II is the commercial version of Ocam I Improved reliability Improved performances Improved environmental conditions (can work with

air and water temperature up to 40°C) Detector safety (over-illumination) More compact for integration on telescope

FAST DETECTORS FOR LGS

The beginning of FP7


LGSD specifications

LGSD = Laser Guide Star Detector• 24 µm pixels, 100% fill-factor

• 84 x 84 sub-apertures (goal 126 x 126)

• 20 x 20 pixels per sub-aperture (to cover spot elongation) 1680x1680 pixels

• 400-800 Hz (for various AO modules)

• RON < 3e- (goal 1 e-), QE > 85%

• Good image lag, charge diffusion, PRNU, cross-talk, non-linearity, cosmetics, RON and dark current variations, stability w.r.t. environment (for centroiding quality)

• Low latency, fully packaged

• Goal: Possible re-use for NGSs WF Sensing

Previous ESO developments 2007: 4 Feasibility studies for EELT LGS WFS detector, 50 k€ each, 2 of

them funded by FP6-ELT Design Study “Market survey”

2008-2009: 3 Technology Demonstrator contracts, 400 k€ each, 2 of them funded by FP6-ELT Design Study “Manufacture of a small array of pixels to prove noise performance”

The current FP7 phase : NGSD

Natural Guide Star Detector = Scaled Down Demonstrator for the LGSD.

Its purpose is :1) To develop a detector that can be used for first light NGS application for the EELT2) To demonstrate the feasibility of the LGSD, without the high costs associated with more engineering tasks such as:

Integral Peltier package, and/or Extension of the dimensions of the device such that stitching is

required.

Specifications are identical to the LGSD ones, except for: 672 x 672 pixels instead of 1680 x1680 4 e- RON instead of 3 e- Relaxed image lag (5 % instead of 2 %) Manufacturers standard package (simple packaging to keep costs down) No Peltier cooler


NGSD Call for TendersFollowing ESO procurement rules: December ‘09: CfT sent to 34 companies/institutes in Member states and

USA February ‘10: 2 Tenders received 10th March ’10: Technical, Managerial and Contractual evaluations

provided to a Contract Awarding Committee May 5th : recommendation from the Contract Awarding Committee to ESO

Finance Committee to award one NGSD contract to e2v (UK). Approval by ESO FC.

May XXth: contract signed with e2v


Stabilize the World leadership of Europe on Fast Detectors and Cameras

Plans for the future


Fast detectors - Opticon Board Malta 19

Firsts of this technology:

- Visible CMOS detector for the first time in astronomy- Back-side illuminated CMOS- Build-in Digital Outputs

But no real testing possibility of this detector outside e2v and production camera not planned, just prototypes .

XAO detectors for 3rd generation of instruments and ELT À compléter….


Fast detectors - Opticon Board Malta 21

Opticon FP7 call 2 detector proposal : beyond what was already developped (à revoir…).

Same philosophy as previous successful detector activities : few goals, few partners with world class know how …

1. WP1 Upgrade of OCam to operate the CCD220 at 2.5-3 kHz frame rate for XAO instruments such as SPHERE and EPICS (following FP6 activities), improve noise (<< 1e), and characterize the system. Industrialize it.

2. WP2 Develop a production camera system for LGS CMOS detectors to test the detector in the labs and that will be used afterward on the VLT and E-ELT (following FP7 call 1 activities). Develop interface with Sparta RTC. Industrialize it.

Actors (preliminary): LAOG: management/system, camera head, detector/system characterization LAM : camera controllers, interface with Sparta. ESO (interface CMOS controller/Sparta, specifications, end user on telescope) Industrial partners

WP2.1 Management Scope : management of the WP Fast

Detectors and Cameras. Lead : CNRS (LAOG – P. Feautrier) CNRS/LAOG will coordinate the WP2

activity, prepare the key specifications for the other WPs, monitor the WPs, organize study and design reviews, prepare the regular reports and detailed work plans for the OPTICON management.

Funding: 50 K€.


WP2.2 CCD220/Ocam 2.5 kHz Scope: upgrade 3rd gen VLT Instruments and prepare XAO for

ELT (EPICS) Goal: decrease Ocam current noise down to 0.1-0.2 e and

increase speed to 2.5 kHz (goal 3 kHz) with redesign of the controller. Prepare industrialization.

New generation of amplifiers and gained experience during FP6 allows to increase speed and noise performances of Ocam allowing to use the CCD220 for the third generation of XAO system and prepare XAO for ELT.

This means a complete redesign of Ocam for this goal.

Partners:

LAM (lead), controller.

LAOG : camera head, camera testing

WP2.3 All-Digital C-MOS Controller Scope: upgrade for 3rd gen VLT Instruments.

Goal of the WP: create a flexible architecture by combining the new technology CMOS controller with an FPGA and fast programmable I/O.

- The new CMOS detector developed in the framework of the FP7 WP2 allows for an all-digital controller. A very high miniaturization can be achieved by companies operating in the high-end embedded computing that are able to pack the detector with a powerful FPGA in the same PCB and equipping it with programmable fast I/O. - The presence of the FPGA allows for intelligent fast on-the-fly processing as well as allowing for different protocols and interfaces to be used for different applications. - The primary goal of this WP is to integrate the CMOS detector and controller , an FPGA and several fast I/O ports industrializing the prototype under development at LAM. - Secondary goal: implement SPARTA+ interfaces and prototype advanced features like pixel multiplexing and switching, while allowing LAM interfaces to be implemented.
