stav experimentlnej fyziky SAV v Koiciach a H1 experiment H1 kolokvium, Praha18.5.2007 J. Ferencei, EF SAV Koice Histria Prprava experimentu Naberanie dt a fyziklna analza Upgrade detektora Zhrnutie

Prv kontakty medzi DESY (formujcou sa H1 kolaborciou) a eskoslovenskmi stavmi (Praha, Koice) v rokoch 1985-1986 (Bechyn -> Hartwig Spitzer).

Memorandum of Understanding medzi DESY a eskoslovenskmi stavmi podpsan v marci 1987.

Dohoda o spoluprci podpsan v jni 1988 (za EF SAV Michal Seman).

Po rozdelen SFR Praha a Koice = nezavisl plnoprvne lenstvo stavov v H1 kolaborcii.

Dohoda o spoluprci medzi DESY a eskoslovenskmi stavmi

Len vaka vemi zkej spoluprci s naimi praskmi kolegami a presvedeniu a tvrdohlavosti Michala Semana - vtedajieho riaditea EF SAV - mohla by v tej dobe participcia Oddelenia subjadrovej fyziky EF SAV v Koiciach v H1 experimente realizovan.

pecifikou tej doby bol vek entuziasmus celho oddelenia a i dostupn nemal finann prostriedky (op hlavne vaka Michalovi Semanovi).

LOI summary H1 LOI was very well received and applauded

but collaboration was severely understaffed and underfinanced only minor US support (Davis) Karlsruhe not allowed to join (no uranium!)

IN2P3 very reluctant to give support

Calorimeter not covered at all!We were saved mainlybythe eastern europeans!F.Eisele: 20 years of H1, La Roche, September 2005

Consolidation towards TP first very big step: Lebedev institute - Luminosity counters , iron Yoke, built in Leningrad ITEP: - iron toroid Prague and Kosice ( calorimeter engagement) Cracow (calorimeter infrastructure) Zeuthen ( tracking chambers)Collaboration management: spokesman : F. Eisele ( from may 86- 92, twice reelected) technical coordinator: F. Brasse (sept. 86 only) 1. Executive committee Enlargement of the collaboration: - H1 as prime choice for the engagement of eastern institutes (we would be nowhere without them) Not just delivery of goods which solved our finance crises but mainly competent, enthusiastic collaborators which helped solving our manpower problem and good friendsBrussels (outer MWPC), Aachen III (Fluegge) and rearrangement ofDetector responsibilities ( Do calorimeter)F.Eisele: 20 years of H1, La Roche, September 2005

H1 experiment na viac ako dve desaroia pozmenil a poznail v tom najlepom slova zmysle chod oddelenia. V rmci tejto asti na oddelen vyrstol cel rad expertov v najrznejch oblastiach fyziky elementrnych astc, ktor obstoja i vo svetovej konkurencii.Urite som na nieo/niekoho zabudol, za o sa u dopredu ospravedlujem.
