Purpose of meeting
· · · · Introduce the product Introduce the people Trigger feedback from users Identify areas requiring attention

· We ask for your understanding that this event cannot be a tutorial on how to use NGC. However:
­ All presentations will be posted at www.eso.org/projects/ngc ­ References to documentation will be provided ­ Please tell us your needs for more information (e.g., by email to NGC@eso.org)

The mission
· ESO's 2 detector departments (IDD and ODT) are charged with providing the detector systems for all LSP instruments:
­ Standardization and reliability (LRU's) ­ Expertise with detector systems not as widespread in ESO community as for other areas

· Common umbrella: detector controller (electronics + S/W)
­ Provides signals to generate, collect, transport, and measure photo signal ­ Creates and delivers image files ­ Needed for scientific imaging and signal sensing (AO WFS)

· Detector controllers are among the most complex products designed and manufactured by ESO staff.

Detector controllers @ ESO
· NGC precursors at ESO:
­ ACE (optical) ­ FIERA (optical) ­ IRACE (infrared)

· After 17 years of flawless service, ACE retired with EMMI blue · FIERA and IRACE were the first standard controllers at ESO · Very successful: downtime in 10 VLT years ~0.1%! (cf. NGC Reliability Analysis VLTTREESO136604578) · But, after ~12 years, both FIERA and IRACE are aging:
­ more and more obsolete electronics components ­ new detectors have lower noise, are faster and larger, have more outputs, require wider range of voltages, etc. ­ extremely demanding signalsensing applications (AO WFS)

Lessons learned
(http://w4/projects/odt/NGClessonslearned.html)

· Don't miss the opportunity to get valuable advice from projectexternal reviewers. · Merging 2 different working cultures is not trivial. · Merging 2 highly successful teams can be more difficult than any other combination. · Give project coownership to everyone ­ but don't let everyone own everything. · We've built (and continue to build) not just a very good controller but also an excellent team.
