  1. Status of theanalysis software Evgueni Goudzovski (SNS & INFN Pisa) P326: Ke2 run meeting CERN  March 15, 2007

  2. Compact & Cmc • COMPACT • General functionality is suitable for Ke2 analysis; • A request to propagate the HODhit structure from CMP to SCMP (MaChit structure seems a good place); • A suggestion (by Massimo Lenti) to use NHOD signal along with E/P; need to propagate the NHOhit structure to SCMP. • CMC • TURTLE beamline configuration for 2007 simultaneous K+/K–beams of 75 GeV/c provided by Niels:~eagroup/database/turtlin/k12k+e2d~eagroup/database/turtlin/k12k–e2u • TURTLE description included into (private) CMC by Dmitry; • Run-by-run CMC fine tuning (magnetic fields/alignment/beam geometry) is foreseen in 2007 as for 2003/2004 once the HCMP split of the data (only Q1 trigger) is available. [Venelin?] [to write: counter number, time, ADC count, overflow condition] [Dmitry]

  3. CMC: 2007 beam line DCH1: x=3.5cm, y=0RMSx,y=0.29cm Deviation of the beamsfrom the Z axis MNP33 defl. @1200A: 3.5mrad x Turtle’2007performance in CMC isvery similarto the expected one K+ 3.9cm 3.5cm z TRIM3 defl.: 0.3mrad K– FinColl:–18m LKr:121.08m DCH1:97.09m MNP33:108.97m PK=75GeV/c, RMS=1.8% Col.plane: RMSx,y=0.33cm dx/dz=0.3mrad, dydz=0 RMSx,y=0.014mrad PK, GeV/c

  4. Cdr, Hepdb, L3, CmpMon • HEPDB • HEPDB service from IT is no longer available in 2007; • Venelin suggested that calibration software could be upgraded to be able to write to AFS. • CDR • A meeting with IT should be organized to find out if CDR serverswill use SLC3 or SLC4, setting up the data pool, etc. • CDR operation with SLC4 would require upgrade of R/O from NFS mounts to RFIO. • A proposal for responsibles: Stefano Venditti, Simone Bifani. • L3 • (E/P>0.5) cut can safely data volume by a factor of ~3; • The algorithm should be implemented into L3. • Compact monitor • Histoscope libraries to be recompiled for SLC4; • The set of values to be monitored is developed (suggestions welcome!). [Volunteers needed] [Venelin/Stefano/Simone] [A tutorial from Venelin is expected!] [Mainz] [Dmitry/Evgueni]

  5. Online and offline filtering MinBias 2004 SCMP size: 4,000 Ke2 250 GB Similar estimation for 2007: 120,000 Ke2 7.5 TB L3 filter (E/P>0.5+downscaled+all 3track): suppression f=3  2.5 TB Computing task force estimation 8 TB • Possible offline filtering: • Ke2 filter (based on stricter E/P, extra activity?) should aimto reduce the data volume to below 0.5TB(compare: 2003+2004 K3asymmetry sample amounted to 1.23 TB); • 2) K3 HCMP split of Q1 trigger (size: ~ 7.5TB/5/50 ~ 30GB)for CMC tuning purposes.
