PreProcessor Module (PPM) - later than planned, but... Final ASIC prototype is OK MCM now OK

Substrate problem fixed by change of material PPM stand-alone tests now nearly completed

System tests Many subsystem tests done without PPM

e.g. 5 DSSs 3 CPMs CMM (crate) CMM (system)

Full system tests with PPM starting very soon Will participate in test-beam in

August/September, including 25 ns run Aim to integrate with

– Calorimeters and receivers– Central Trigger Processor– RoI Builder– ATLAS DAQ, run control environment, etc.

Produce simple triggers based on calorimeter signals

Barrel muon triggerBarrel muon trigger Preproduction of “Splitter” boxes

completed Main production on the way

Prototype of final-design “Pad” boards evaluated in lab and (last week) at 25 ns test beam

Seem to work well, but test-beam data still to be analysed

Design completed for revised version of CM ASIC

Interaction in progress with IMEC on placement/routing plus simulation to check design

Very urgent! More Pad boxes being prepared

for chamber integration tests Number limited by availability of

prototype ASICs (old version)

Correlation in measurements between two BML doublets

Endcap muon triggerEndcap muon trigger System operated successfully in last

week’s 25 ns test beam with MUCTPI and CTP demonstrator

Even better efficiency than last year Many improvements to software

Will test new PS boards with revised version of SLB ASIC in test beam August/September

Revised version of SLB ASIC is being evaluated in lab tests

Trigger part passes all tests Problem detected in readout part for

certain sequences of L1A signals Probably very localized and

hopefully only very minor revision to design required, but still under investigation

All other endcap ASICs already final

Final prototypes either available or coming soon (layout, production)

Tight schedule to test, commission and integrate for test beam later in summer

LTP Prototypes just received

MUCTPI Work queued behind CTP Only one kind of module needs to

be upgraded to achieve full functionality

Existing “demonstrator” adequate in short term

LVL1 ScheduleLVL1 Schedule

Re-baselined in line with current status and plans Schedule for calorimeter and central trigger electronics matches

availability of detector systems Production of on-detector muon trigger electronics is later

than we would like for integration with detectors Very tight schedule to have barrel electronics available in time to

equip chambers before installation Late submission of revised version of the CM ASIC Try to advance ASIC schedule if at all possible Need to prepare for very fast completion and testing of electronics

once production ASICs become available Need to prepare for efficient integration of electronics with

chamber assemblies prior to installation End-cap electronics schedule also tight for integration with detectors

in early 2005 Detector installation is later than for barrel, so not as critical

Installation ScheduleInstallation Schedule

According to present schedule, final availability of all LVL1 subsystems is still driven by detector installation schedule Latest ATLAS working installation schedule (v. 6.19) shows last TGC

chambers (with on-detector trigger electronics) installed January 2007 Leaves little time for commissioning of on-detector electronics

before we lose access prior to first beams Action defined for discussion with TC (and Muon PL) to see if

there is scope to optimize the installation planning

HLT/DAQHLT/DAQ Major activity in the present phase is the test beam

Support for detector and for LVL1 trigger tests Organization in “support teams” who are first point of contact

– Call on experts when necessary Dedicated training sessions were organized for the team members Team members participate with experts in problem solving

– Good way to spread expertise Electronic log book very useful

– Could extend use to detector systems HLT/DAQ studies

Preparation and planning for dedicated period in August– Aim to operate HLT/DAQ system to gain experience in a “real-life”

environment» Will need support from detector systems

Generally experience at test beam is very positive for T/DAQ However, work at the test beam takes a lot of effort

In parallel, continue development and system evaluation work ... within the constraints of the available effort

E.g. Dataflow measurements and modelling

Detector integration with DAQ at H8Detector integration with DAQ at H8

Muon Detectors TGC’s, MDT fully integrated

Extended running in combined mode during 25 ns run last week together with MUCTPI (sometimes triggered by CTPD)

RPC almost fully integrated Data were successfully taken in stand-alone mode

Calorimeters Tiles fully integrated in data-taking mode LAr integration well advanced

Inner Detectors Started for TRT and pixels; plan to integrate SCT later

The exercise of joining detectors together has proven to be “easy” if the detector segment has been properly done

according to the TDAQ prescriptions

HLT integration for test beamHLT integration for test beam

The infrastructure for the EF is prepared An EF cluster has been divided and pre-assigned to different detectors

The configuration allows, nevertheless, to dynamically assign more CPU’s to the partition that requests it

The main work now is to get ATHENA integrated Scheme of having “rolling” unique version of the offline software

(8.2.x) specially maintained for the test-beam working well We are now trying to put in place the automatic procedure that

sets ~80 environment variables! The Gatherer is integrated

Allows for aggregation of histograms across multiple processors The LVL2 commissioning is progressing well

A LVL1 result has been successfully read out by the L2PU Progress is being made in integrating algorithms
