15PREHISTORYStarting points in the 50’s:a) Hungarian “MANHATTAN-Project” KFKI (1950) and ATOMKI (1954)b) Experimental Cosmic Ray PhysicsResearch reactor, MeV accelerators, nuclear electronics and detectorsBeginning of HEP in the 60’s:JINR-Dubna membership: HU was providing personel and instrumentationMost active period Serpuhov 70 GeV acceleratorHungarian colony in Dubna includes more than 50 scientists and engineersFirst contacts to CERNa) CERN-Dubna agreement (1964) Some people of Dubna staff can visit CERNb) HAS-CERN : “scientific visitor” agreement (1970)1-2 year fellowship for theorists and experimentalists alternatively
16LEP-L3 the first Hungarian CERN experiment By special grant of HAS a Hungarian team as official BUDAPEST group from thebeginning became the member of the L3 experimentThe grant was just enough to cover the obligatory yearly “running cost”,but no resource for construction. Minor hardware contribution was achievedto the SMD Si-detector monitor system.Main contribution: core-software development, data processing, physical analysisIn 1995 the group was reorganized to concentrate for gamma-gamma analysis.Due to the complexity of the analysis software, effective work was only possibleduring the short 1-2 months visiting periods of the Hungarian team members toCERN. The home computer base was under-developped to install the necessaryprogram packages.In 1999 the ATOMKI-Debrecen University team also became an official member.
17What did we learned from L3? By the contemporary Hungarian standards the team got relativelylarge financial support, but the real sum turned out to be marginalcompared to western levels of funding.Most of the team members had no real direct affiliation to any subdetector,they were drifting around according to occasional short-term grants.E.g. the key person of the gamma-gamma project left for OPAL continuinghis successful carrier there. Thus we reached only 1 complete PhD and2 “half” ones.Trivial conclusion: We missed the critical massBUT! There is no universal way to the success. Let us try some variants!!!

44The CRITICAL POINT’s puzzle is well characterized by the letter of leading theorists to the SPSLC Committee which was thehighest scientific decision body of CERN at that time:

46STRATEGY DOCUMENT 14 July 2006, Lisbon 9 Strong interactions and the interface of particle and nuclearphysicsA variety of important research lines are at the interface between particle and nuclearphysics requiring dedicated experiments; Council will seek to work with NuPECC inareas of mutual interest, and maintain the capability to perform fixed target experimentsat CERN.QCD plays a multiple role in particle physics. On one side QCD is one of thecornerstones of the SM, and in spite of its phenomenological successes more work isnecessary to fully establish its quantitative predictions in the long-distance and stronglyinteracting regimes. On the other side, QCD is a crucial tool for the measurement of theelectroweak parameters of the SM (e.g. the quark masses and mixings) as well as tosearch for BSM phenomena, both at low energies (e.g. in the decays of K or B mesons)and at high energies, where the production of new heavy particles may be hidden bylarge QCD backgrounds, and often manifests itself in the form of multijet signatures.Finally, QCD leads to new states of matter, when temperature and densities exceed thevalues beyond which quarks and gluons are confined inside hadrons. Progress in thefield of strong interactions, guaranteed by a diversified programme of national orregional facilities operating at different energies and with different beams, plays animportant role in the future of particle physics.In parallel, a fixed-target programme, to specifically address the problem of identifyinga QCD critical point by improving and diversifying the available data, could beimportant. The ability to carry out fixed-target experiments at CERN with heavy ionsbeams should be preserved.

4812 officially acknowledged high energy physics experiments. From this table one should notice the fact that in the huge CERN Laboratory exists only12 officially acknowledged high energy physics experiments.There is 6 planned experiments at LHC:ALICE, ATLAS, CMS, LHCb, LHCf and TOTEMandan other 6 registered experiments at SPS:CNGS1(OPERA), CNGS2(ICARUS), NA58(COMPASS), NA61(SHINE), NA62, NA63.Hungary has relative large groups in CMS and ALICE, but they representonly a small minority amongst the few thousand participants.In the small SHINE/NA61 experiment already 10 people represent a strong contingent,but our role even more significantbecause this is the only experiment in CERNwhere Hungarians are occupying leading positions:G Vesztergombi together with M. Gazdzidki are the spokespersons,responsible separately for the proton- and heavy ion physics, respectively.Beyond these administrative posts it is more important that the position of RUNcoordination is also in Hungarian hand. Z. Fodor (RMKI) is the Technical Coordinator,who is the commander of the real experimental work on the floor,knowing all the technical and scientific details.
52Detector development – engineering The NA49 data acquisition rate was limited to Hz with a duty factor of 25% (effective rate around 1 Hz) and that seriously limited the statistics that could be collected for all measurements, includingthe high pT measurements.With this upgrade we can achieve a readout rate in excess of 40 Hz.An additional factor of 2 will be gained by reducing the sampling frequency of drift electrons .An overall readout rate exceeding 80 Hz will be thus achieved.With the typical 25% duty factor of the SPS that will result in an effective rate in excess of 20 Hz. A total of 240 MB and 8 CD were produced.PCI-busin„1” PCIn ALICE detector one finds similar TPC as in SHINE, which has about only 3 timesmore (500,000) pads, but using 500 DDL channels and 200 CPU units to collect the data.In case of the SHINE detector, however, one uses about 60 times smaller number (8) ofDDL channels and 200 times less number of CPUs, i.e. the new SHINE-DAQ systemcapable to handle similar order of magnitude data volume by a SINGLE COMPUTER!!!
