Software needed (H8)

• DAQ-1– BE installed

• ROD emulator• Beam crate readout process• Crate controller and message system

– Inherited by tile-cal software

• Monitoring• Calibration

DAQ-1

• Back-end– installed (v 0.0.10)– to be upgraded– some experience (with 0.0.8)

• Data flow– some experience in Roma (S. Veneziano)– we need to install it in our setup

E. Pasqualucci

ROD emulator• ROD emulation (phase 1)

– AMT and CSM under test in Roma3 (P. Branchini)– Hardware access:

• Libraries developed on Digital UNIX• Based on KLOE low-level libraries• To be tested on LynxOS

Monitoring• Histograms

– Number of hits vs tube id– Time spectra– Time spectra with input selection

– Straight line tests (plot t2 + 0.5 * (t1 + t3))

• Track fit• Root or “Rbook”

Calibration

• “Tube t0”– fit of time spectra

• Space-time relations– 5 to 10 iterations on 104 tracks– errors < 10 m– 60 ms/ev on 500 a MHz Pentium

Our testbed

• 6 PCs– 2 Celeron 500 MHz, 128 MB RAM– 4 P2 450 MHz, 256 MB RAM

• 1 server (P2 300, users and software)• Distributed data disks (3*45+2*61 GB)• Fast Ethernet and hidden Gigabit networks• => L2 Farm OK• 2 VME crates• RIO 8061, waiting for 4 RIO 8062

Software needed (DAQ slice)

• Complete simulation of events:– ROI + ROB (test L2)– ROI + ROD (test ROD + L2)– FE modules (test L1) - (A. Nisati)

• L1 - L2 interaction + L2 response• Integrated Reference Software• Trigger performance monitor (rbook ?)• We already have

– muon L2 algorithm in RS frame– L1 simulation
