5. Contribution IEP SAS Košice to ATLAS - the proposal, development, realization, tests and maintenance „on-line“ (electronic) calibration for HEC - important participation in development of the “cold” electronics for HEC - the production of the distribution boards in the cryostat for HEC (signal, calibration and high voltage) - the production of the magnetic shielding and isolation's elements for low voltage sources - the filter production for regulation of the parameters for liquid argon (filter-boxes) - the proposal, tests and realization of the so called „on-line“ calibration procedure. Today this method figures among basic stones for all ATLAS calorimetry - with the close collaboration with Columbia university we made important contribution in electronic for all ATLAS calorimetry – the FEB (forward read-out boards) development - large method`s contribution to local hadron calibration (LHC) for all ATLAS calorimetry. LHC is today basic methods for signal proceedings in ATLAS calorimetry. - the contribution in Monte-Carlo simulation, testing radiation resistance of the liquid argon detectors - the analyze of the charge symmetry in the dilepton channel - the analyze of the production top antitop mechanism in the dilepton channel ATLAS kalorimetra (P. Stríženec, D. Bruncko, E. Kladiva, M. Seman)
