RECFA meeting, Bratislava, October 1-st 2004

H1 experiment and DESY

PHYSICS

IEP SAS Košice in H1 Hardware contribution: Various contributions into the design of readout and trigger Serial download card for LED system Trigger bit card for the SpaCal output bits synchronization and connection with central trigger (NIM A 515 (2003) 543)

Software contribution: On-line data acquisition, monitoring and slow control Simulation and reconstruction in SpaCal calorimeter

Contribution to the physical analyze: vector meson study (Acta.Phys.Polon B31 (2002) 2357)

Concentration on H1 calorimetry

Methodical problems spatial clusters resolution in Spacal CJC-BDC-SpaCal matching SpaCal off-line calibration, timing, data quality check

Participants: A core of calorimetry group ( 1 Dr., 2 Dipl. Ing.) with strong DESY support Košice (2 Dr., 1 diploma student), Bratislava since 2004 (3 Dr.) 2 PhD students (Heildeberg, Kosice/Brussels)

H1• Evidence of higher

excited states ρ(1450) and ρ(1700) in elastic ep channel

• Analysis in progress

H1Example: Spatial resolution of the SpaCal

Electron entry points into 4x4 cm SpaCal cell

Reconstructed entry points using traditional method

Reconstructed entry points using improvedalgorithm.Resolution 4 mm

H1 and future physics at Linear Collider

• Extension of the 2D method

• Development of the 3D reconstruction algorithm used for an optimization of the layout of a sandwich (Pb/scint) calorimeter for a future linear collider

• R&D for HCAL at Future Linear Collider– Optimization of the granularity in depth– Optimization of the 2D granularity in measured co-

ordinates– Optimization of the number of read-out channels– Effective discrimination of

• Hadronic showers

• Electromagnetic showers

• Ionizing tracks

Financial support

1987-1992 Read-boards production, BEMC trigger (about 1.1 mil. DM)

1994 no projects support

Since 1995 ... Start support for Slovakia participation at CERN

... Other HEP activities ... a constant, but very small support

May 2004 ... Slovakia -member of EU ...

We would like present to Slovakia community that Slovakia has big profit from our participation in CERN, DESY... but how to do it? HEP OUTREACH

Microcosm - DESY exhibition in Kosice, 1997

CERN WEB university:

Dr. R. Parker „Telecommunication for the future“

5-day series of lectures (CERN, Finland, Slovakia)

March 2001

18 secondary schools participated in the Physics on Stage, Life in Universe, (on line webcasting from Geneva, Amsterdam,…)

Our presentation in Amsterdam

The base for communication is high-speed Internet…
