Instrument Control Systems 2014 NGC controller Leander Mehrgan Instrument Control Systems Seminar 2014, 20th-24th October ESO precursor controller IR data acquisition system and ACE as optical controller IRAC camera and its controller 1987 ACE controller at NTT La Silla Sequencer programming language: Assembler Instrument Control System Seminar, 20th-24th October 2014 IRACE, InfraRed Array Control Electronics In 1994 the Infrared Detector Group started with the development of the IRACE controller. Instrument Control System Seminar, 20th-24th October 2014 IRACE, InfraRed Array Control Electronics In 1994 the Infrared Detector Group started with the development of the IRACE controller. IRACE Giga board for data transfer with one Gigabit per second Instrument Control System Seminar, 20th-24th October 2014 IRACE, InfraRed Array Control Electronics First light with ISAAC in 1998. From 1998 to 2008 IRACE was the ESO standard controller for InfraRed application. This controller was based on Transputer processors. gigabit fiber for data low speed fiber for command Instrument Control System Seminar, 20th-24th October 2014 FIERA, Fast Imager Electronic Readout Assembly In 1995 the Optical Detector Team (ODT) started with the development of the FIERA controller. clock board 4 channel video board Communication board Instrument Control System Seminar, 20th-24th October 2014 FIERA, Fast Imager Electronic Readout Assembly From 1998 to 2008 FIERA was the ESO standard controller for Optical application. This controller was based on DSP processors. FIERA 16 output video channels for NAOS chip Instrument Control System Seminar, 20th-24th October 2014 FIERA and IRACE are still used by many instruments at ESO telescopes Using IRACE controller ISAAC CONICA SOFI CRIRES HAWK-I S SINFONI VISIR IRIS PRIMA FINITO Using FIERA controller UVES NACO X-SHOOTER GIRAFFE FORS VINCI VIMOS VISTA X-SHOOTER Instrument Control System Seminar, 20th-24th October 2014 OmegaCAM EMMI ESO detector controller Both controller have been extremely successful. but various limitations, e.g.: mass (OmegaCAM: ¼ ton), volume, heat dissipation obsolete components voltage range and swing speed, number of channels 2 successes (= 2 costs) Therefore …. Make new design, taking advantage of new technologies Do it as a joint IR+ODT effort, merging all past experience Instrument Control System Seminar, 20th-24th October 2014 NGC, New General detector Controller Both development teams, FIERA and IRACE, merged into one team, the NGC. In 2004 the NGC team started with a new design. Features of the NGC: No parallel bus system, only high speed serial links Central element on each board is a Xilinx FPGA Digital parts, like RAMs, FIFOs, and the sequencer are fully implemented in the FPGA Data and commands time multiplexed transferring Instrument Control System Seminar, 20th-24th October 2014 Different type of NGCs SCI-NGC: the scientific NGC, which is used for all type of detectors AO-NGC: used to readout the e2v CCD220 detector with a very compact, high speed integrated controller. The same back-end interface is used for both NGC types. Core of the SCI-NGC Instrument Control System Seminar, 20th-24th October 2014 WFS camera (AO-NGC) Different type of housing The NGC provides different type of housing: Compact (no water cooling) Fanless housing (needed for GRAVITY and MATISSE) Instrument Control System Seminar, 20th-24th October 2014 Six-slot (with water cooling) NGC interface to other systems The NGC controller provides a direct interface to the SPARTA and VxWorks based Power PC systems. NGC DCS Needed for GRAVITY, GRAAL, GALACSI GUI instruments NGC RTD Instrument Control System Seminar, 20th-24th October 2014 SPARTA RTD NGC, New General detector Controller The NGC controller is a modular, customizable system Backplane AQ-32ch module 10 MHz FEB module Transition module Visible NIR MID-IR Instrument Control System Seminar, 20th-24th October 2014 Visible WFS NGC, New General detector Controller Just like “Lego” blocks we can combine different modules to cover our needs. Video Basic Videointerface board-10MHz board Basic board Fiber cable Power supply box Power supply cable A system like thisPCIexpress has been using to readout the SAPHIRA detector of the GRAVITY instrument LLCU Instrument Control System Seminar, 20th-24th October 2014 NGC, New General detector Controller Just like “Lego” blocks we can combine different modules to cover our needs. MUSE I MUSE II MUSE III MUSE NGC system readouts 24 CCD detectors simultaneously Instrument Control System Seminar, 20th-24th October 2014 MUSE IV Status of the NGC NGC systems are already being used by many instruments Since 2012 also operational at the telescopes. GALACSI / GRAAL MATISSE VISIR MID-IR AQUARIUS MID-IR NGC GRAVITY NIR AO NIR WFS SAPHIRA NIR NIR Visible WFS Visible SPHERE Instrument Control System Seminar, 20th-24th October 2014 Visible MUSE Summary ESO has a long history of developing and maintaining its own controller, one of the reasons behind NGC success The NGC is now in routine operation at the VLT and has reached a very high level of maturity It is very adaptable and continues to meet all instrumentation needs With the SCI-NGC and AO-NGC combinations, ESO is able to readout any type of detector Having the NGC as a uniform controller platform at the observatory, we have an extremely useful and maintenance friendly systems on the mountain. With further development the NGC will meet the requirements of detectors for the ELT Instrument Control System Seminar, 20th-24th October 2014 Thank you very much for your attention Instrument Control System Seminar, 20th-24th October 2014
