Brief History of HEP in Austria

1954: Foundation of CERN1959: Austria becomes Member of CERN1959-66: Small group at the Vienna University analyzing photoplates from nuclear reactions, later analyzing bubble chamber pictures from CERN1966: Institute for High Energy Physics of the Austrian Academy was founded.. With groups for “counter” expts., bubble chamber expts., theory, electronics, mechanical workshop. Institute was then involved in various experiments at the ISR and SPS, and in a series of bubble chamber experiments also experiment in Serpukhov1968: Exp. group in Innsbruck collaborates with Vienna in bubble chamber expts.1978: Institute joins UA1 collider exp., 1983: discovery of W and Z bosons


1984-->: Vienna participates in DELPHI at LEP, since 1992 in NA48 (CP violation in K0), since 1992 in CMS at LHC since 2001 BELLE at KEK(Japan)

Innsbruck: ALEPH at LEP, ATLAS at LHC

Funding of HEP

Institute for HEP of the Academy of Sciences, Vienna: funded by the Academy (Personnel + Material). The Academy of Sciences is an autonomous institution receiving a total budget for ~15 institutes from the Ministry of Research

Experimental HEP group, Univ. of Innsbruck: Material costs funded by the Ministry

Theory groups at the Universities (Vienna. Graz, Innsbruck) supported by the Research Council (FWF)


Funding of HEP

Until 1995: Experimental HEP was also supported by the in addition Research Council

1995: Decision by the Research Council to not support anymore exp. HEP !Reasons: “Big science”, HEP does not fit into the reviewing system.“If Austria is member of CERN, the Ministry should (directly)provide the means for participating in the CERN program”.

Since 1995, direct funding from Ministry worked so far forNA48, the LEP experiments DELPHI and ALEPH, and the MoU for CMS and ATLAS construction and theMoU for maintenance..

Conclusions

• Experimental HEP strongly centralized in the Institute of High Energy Physics of the Academy of Sciences in Vienna

• only one university institute in Innsbruck• no chair in HEP experimental physics in Vienna

• HEP community small in comparison to other small member states

• community more or less constant, substantial fraction close to retirement• problems in getting students (reasons: no university institute in Vienna, big time interval between LEP and LHC, competition from other fields)

• Budget more or less constant, no increase in sight, HEP no ‘priority’

• without additional direct funding by Ministry participation in CMS impossible (MoU for construction, for maintenance & operation; MoU for computing still to be negotiated)

• Doctoral student programme for technology crucial
