Offline meeting

• Outcome of Scientific Committee

• Status of MC04

• Proposal for a minimum bias EvCl sample

• Other offline activies:– Reprocessing– Dead wires– MC 2001/02

LNF 9-Jun-05

Remarks from LNFSC and CSN1Offline status/priorities discussed at closed session of LNFSC (24 May)

– Need for prompt MC04/05 production emphasized by LNFSC members

– Requests for additional CPU and disk space supported

Requests for computing upgrades discussed with KLOE CSN1 computing referees yesterday (8 Jun)

– 6 new 4-way 1.5 GHz Power5

1 Power5 = 8 B80 new machines equivalent to 192 B80s

Total KLOE computing power 200 392 B80s– 20 TB of additional disk space for DST staging

Requests will be discussed at the next CSN1 meeting in Trieste 6-7 Jul

One strong possibility purchase 2 of 6 boxes now– No gara needed, machines could arrive in less than 1 month

Update on MC04-05 (1/3)

New interaction region

– CB implemented, needs test, timescale?

Attenuation lengths vs endcap module numbers

– CB attentuation lengths reversed. CLUADJUST correction?

Energy scale calibration

– Need to clarify above correction. Who?

Regeneration and nuclear interaction

– CB has divided interaction code for EmC and other regions

– Who will test? Timescale?

EMC time resolution

– Insert C. Gatti correlated term in t0 smearing code, uncorrelated term in clustering simulation code

– Who?

Update on MC04-05 (2/3)

generator

– FN working on adding FSR

Additional generators

– KSee (CG, TS) added to MC (CB)

– e (?)

– ee (?)

– KSee exists (FB, VP), needs to be added

Trigger

– Simulate period with high time jitter

– Quality check on torta

– Simulate DC trigger threshold

– DISH map

– Report from BS, MP

Update on MC04-05 (3/3)

DC tracking resolution

– AA, PDS, MM, TS volunteers

– No work underway yet

Correlated noise in DC for charged kaons

– EDL, PDS + charged kaon group

– No progress yet

lsb insertion code

– MM in progress

– Some code written

Fix discrepancy in SQZ library

– MM in progress

– FIXIS works but source of problem not yet fully understood

Other offline activities• Reprocessing:

– To date 85 pb-1 of 2002 have been reprocessed (from run 23542 to 25000)

– We switch to all the CPUs in the last days (during the DAFNE shutdown), with a rate of 10pb-1/days

– We will continue….

• False dead wires list:– Last week the correct list of dead channel for 2001/02 was inserted in the

DB. At the moment we use test tables. Dcdelete can read test tables or normal

– We started the submission of physmon for 2004.

Other offline activities

• MC2001/02:– The script needs to be completed– Status of the executable?

• Fixis

• Insert the new version of nratag• Fix correspondence of cluster and cell indices to allow background cells

to be identified• Module for downscaling accidental cluster according to Martini-Miscetti

recipe • Beam spread position in z
