• RON < 3 e- @ 50 kpix/s demonstrated with e2v CCD types 44-82 and 231

ü MUSE requirements are met

ü Ditto for KMOS, SPHERE IR T/T WFS, and ZIMPOL

ü NGC much more immune to pick-up noise than FIERA is

ü Successfully installed at ODT test benches

• Start-up time of software < 2.5 s

• Standard ADCs run at 1 MHz; on-going developments:

- 3 MHz version of 32AQ board

- 40 MHz high-speed board

• Improved over-voltage protection

• New PMC I/F board for VLTI applications not using SPARTA

† With1310-nm fiber link, could place LLCUs in central computer room.

General change request not supported by LSP Re-consider for every new instrument

NGC deliveries and production in 2008/2009

Systems are due for:○ MUSE (prototype +)○ KMOS○ SPHERE○ ZIMPOL○ Lab usage

• Two successful revisions of Basic and Transition Board

• 32AQ Board unaltered

• Produced 7 power supply units

• Developed new 2-board housing

with fan (for laboratory use only)

Stock ~sufficient for deliveries in 2009 to:• KMOS• MUSE• SPHERE• ZIMPOL

All accomplished

NGC-AOPlan: • Develop standard WFS module for all forthcoming VLT AO systems

• Test controller from Marseille / OHP / Grenoble: OCam

• Combine NGC digital and OCam analog electronics

• General sFPDP I/F to SPARTA at LLCU level

Status:

• Bias and clock-driver boards received from OCam

• NGC sequencer board derived from NGC basic board

(Xilinx Virtex-5 instead of II-Pro)

• Firmware prototyped

ü First ‘laboratory light’ achieved in November

† Waiting for ESO-Ocam

• sFPDP development starting

• Plausible back-up for CCD220• Device too small for LGS and SH@E-ELT• But OK for XAO with pyramid WFS?• XAO needs 3 kfps – AApnCCDs?

Slide repeated from last year

• Joint usage of ODT test bench continued• Could help MPE-HLL to make good progress

Standard VLT AO WFS system

(GALACSI, GRAAL, SPHERE)

ü Prepared very comprehensive FDR documentation† Waiting for ESO-OCam, NGC-AO, and more detectors• Baseline detector is CCD 220 from e2v • Need to build 15 systems in 2009-2011 (AOD want them earlier)

Nov 2007 ELT AO WFS Possible Developments 1313

Detectors for E-ELT AO WFS

• Feasibility-study phase with 4 contractors successfully completed

• Issued new CfT for Technology (Pixel) Demonstrator

• Awarded 3 fixed-price contracts (all CMOS-based)

• Last one is supposed to enter Design Review in January, 2009

• First one has already reached shuttle-run phase

† Contractors are struggling with combination of speed and read noise

(some find it difficult to just read the requirements)

• Continually refined requirements (models, contractors’ responses, etc.)

• About mid-2009 issue CfT for Scaled-down Demonstrator

ODT and NGC 2008


X-shooter

• FIERA software defines 2 nearly fully independent virtual cameras on one common front-end electronics

• VIS system (with MIT/LL CCID-20)• UVB system (with e2v CCD44-82)ü Requirements-compliant systems delivered to Paranal

Giraffe upgrade

• First deep-depletion device with dual-layer coating (e2v)• Successfully commissioned in 2008 May• Prototype for VIMOS red upgradeüThicker silicon offers decisive advantages - but also suffers more particle hits

Major improvement in red sensitivityMuch reduced fringing

OmegaCAM: between the bodegas

• Shipped to Paranal• Re-assembledü Fully successfully testedü I/F instrument / detector system verifiedü Packed and safely stored• Awaiting VST

† Filters from Barr Ass. broken (again …)

OmegaCAM: one CCD failed

Typically asked questions:

How bad is it?

It’s very bad

Is damage due to transport?

No, it isn’t

When will CCD be un-kaputted?

CCD can’t be repaired

Can it be replaced?

Yes. At cost and risk

Will it be replaced?

It depends

31 CCDs functioning as before!

Here it is

(Identical CCD died years ago under similar circumstances)

Multi-unit Spectroscopic Explorer (MUSE)

(Multi = 24 = MANY)

Tee Pee

• 4k x 4k engineering-grade CCD 231 from e2v extensively tested• Helped to debug 2nd ODT test bench and NGCü Requirements are met• Final detector head just manufactured – will install science-grade CCDü Prototype system to be delivered in March• Agreement reached with AI Potsdam for support of serial production† ESO has become part of MUSE Consortium: extra bureaucracy• TeePee serial production initiated

ZIMPOL (SPHERE)

Originally, ZIMPOL was supposed to provide a VLT-compliant detector system

Now, the ODT may more nearly be supplying a ZIMPOL-compliant detector system

• Comprehensive FDR documentation submitted• NGC system produced

UVES red upgrade• EMMI red released for cannibalism• Installation in 2009 July

VIMOS red upgrade• Contract with e2v signed in 2008 (?)• 5 deep-depletion CCDs due before 2009 August • Installation in P84

FIERA• 2009 releases of VLTSW (incl. enhancements)

Pulpo1• Multiple clean-ups after upgrade attempts on LSP

MIT/LL Phase 4• Have given up on receiving any devices

Miscellaneous
