Achievements since Achievements since CM22CM22

TOF1 included in the DAQ and in the triggerTOF1 included in the DAQ and in the trigger New flashADC (500MHz) installed for CKOVNew flashADC (500MHz) installed for CKOV Computer Clock synchronization fixedComputer Clock synchronization fixed

Not 100% satisfactory: PCs are synchronized to each other but not to the outside world (firewall issue)

Slow progress in including the target DAQ and Slow progress in including the target DAQ and CAM into the online Data StreamCAM into the online Data Stream

Progress has been slower than foreseenProgress has been slower than foreseen



Known issuesKnown issues Limit on the number of particle events

From DAQ itselfs ( about 200 Particles/Spill )Was expected

Technical solutions exist From Online Monitoring ( about 40 Particles per Spill )

Not expected

Need more investigations

Event reconstruction Occasional and marginal mismatch between the number

of particle triggers in different VME boards Recently, dramatic mismatch between the number of

particle triggers in the two crates for some runs

-> Serious Event building problem !

Need more investigations

Interface with EPICS becomes a top priorityInterface with EPICS becomes a top priority



Feed back from userFeed back from user Need better handling of DAQ crashes Need loud, emphatic, and unambiguous

indicators that data are or are not being recorded.



Target DAQ issuesTarget DAQ issues

Progress slowed down Progress slowed down Need consistent integration with the stand alone target

DAQWe want a common software basis for file read/write operations

Target DAQ under deep revisionTarget DAQ under deep revision

Trigger IssuesTrigger Issues


TOF0 and TOF1 trigger implementedTOF0 and TOF1 trigger implemented Particle Trigger selection by hardwareParticle Trigger selection by hardware

There is a plan to implement software selectionNot a priority for the moment

Particle Trigger pre-scaling Particle Trigger pre-scaling Needed because of limitation on the DAQ input

rate Need hardware intervention

Not fully satisfactory -> Need investigation

Need decision on the future of GVA1Need decision on the future of GVA1 Should it stay or should it go ? GVA2 and GVA3 are gone already

Burst Gate Burst Gate CorrelationCorrelation


GVA1 hit

Burst Gate made narrow

No progress achieved since CM22No progress achieved since CM22

Online SoftwareOnline Software

Unpacking library needs upgradeUnpacking library needs upgrade New fADC (V1731) for CKOV New version to be distributed next week

Interface with G4MICEInterface with G4MICE First task is to reproduce online histograms (David Adey) See Software session for more details

Know issuesKnow issues Online monitoring GUI tends to get stalled at the end of a

run Online monitoring histograms are not labeled according

to detector names That is a feature!

Need better Online plots for fADC Current plots found not efficient in detecting broken

channels Not straight forward task (fluctuating baseline)



Front End ElectronicsFront End Electronics

CKOVCKOV New 500 MHz fADC has been installed Performance has to be evaluated and compared to the previous scheme There is no more TDC data for CKOV

TOFTOF TOF TDCs are not properly synchronized. Internal clock has to be

distributed.

For the moment, we use the common Part. Trigger signal in ch0 of each TDC

TOF2: We miss some electronics Shapers/Splitters: In production TDC: One board missing FADC: 3 boards missing

SW (aka Electron Muon Ranger)SW (aka Electron Muon Ranger) A technical proposal has been submitted to the Technical board


FEE IssuesFEE Issues

Cross Talk IssueCross Talk Issue Not yet clearly understood New design is under study

FADC firmware upgradeFADC firmware upgrade Needed to allow significant reduction of data volume

Less samples per Particle event (currently 512 whereas only 60 are necessary Zero suppression (to be tested)

Delicate operation

Splitter/Shaper ProductionSplitter/Shaper Production Board production is finished in Sofia Discrete components are in hand in Geneva Mounting will start in February

Missing TDC/fADCMissing TDC/fADC Shouldbe ordered by Ludovico/Maurizio (funding issues)

SummarySummary

TOF1 has been integrated into DAQ, Trigger and TOF1 has been integrated into DAQ, Trigger and OLMOLM

CKOV readout has been upgradedCKOV readout has been upgraded Many recent milestones have been missedMany recent milestones have been missed

No real show stopper All key issues can be solved before serious things start in May 2009

Serious problem with event building discoveredSerious problem with event building discovered Deserve serious attention First step is to get online diagnostic

Target DAQ will be integrated to Detector DAQTarget DAQ will be integrated to Detector DAQ Work still in progress

FEE for SW/EMR and TOF2 are priority tasksFEE for SW/EMR and TOF2 are priority tasks

Current DAQ issues can still be solved before Step 2Current DAQ issues can still be solved before Step 2
