The Antiproton Accumulator ( AA ) was an infrastructure connected to the Proton–Antiproton Collider (Sp p S) – a modification of the Super Proton Synchrotron (SPS) – at CERN . The AA was built in 1979 and 1980, for the production and accumulation of antiprotons . In the Sp p S the antiprotons were made to collide with protons, achieving collisions at a center of mass energy of app. 540 GeV (later raised to 630 GeV and finally, in a pulsed mode, to 900 GeV). Several experiments recorded data from the collisions, most notably the UA1 and UA2 experiment , where the W and Z bosons were discovered in 1983.
91-541: The concept of the project was developed and promoted by C. Rubbia , for which he received the Nobel prize in 1984 . He shared the prize with Simon van der Meer , whose invention of the method of stochastic cooling made large scale production of antiprotons possible for the first time. Antiprotons were produced by directing an intense proton beam at a momentum of 26 GeV/c from the Proton Synchrotron (PS) onto
182-476: A United Slovenia , first advanced during the revolutions of 1848 , became the common platform of most Slovenian parties and political movements in Austria-Hungary. During the same period, Yugoslavism , an ideology stressing the unity of all South Slavic peoples , spread as a reaction to Pan-German nationalism and Italian irredentism . World War I brought heavy casualties to Slovenes, particularly

Since decreasing the divergence of the beam meant to reduce transverse velocity or energy components, the suggestive term "stochastic cooling" was given to the scheme. The scheme could then be used to "cool" (to collimate) the anti-protons, which could thus be forced into a well-focused beam, suitable for acceleration to high energies, without losing too many anti-protons to collisions with

6552-697: The population of their occupation zone. The most infamous ones were Rab and Gonars . To counter the Communist-led insurgence, the Italians sponsored local anti-guerrilla units, formed mostly by the local conservative Catholic Slovene population that resented the revolutionary violence of the partisans. After the Italian armistice of September 1943, the Germans took over both the Province of Ljubljana and
6643-664: The property of the Habsburgs, who retained control of the area right up until the beginning of the 20th century. Patria del Friuli ruled present western Slovenia until Venetian takeover in 1420. At the end of the Middle Ages, the Slovene Lands suffered a serious economic and demographic setback because of the Turkish raids . In 1515, a peasant revolt spread across nearly the whole Slovene territory. In 1572 and 1573
6734-543: The re-establishment of Yugoslavia in World War II, the first Slovenian republic, Federal Slovenia , was created and it became part of Federal Yugoslavia . It was a socialist state , but because of the Tito–Stalin split in 1948, economic and personal freedoms were much broader than in the Eastern Bloc countries. In 1947, the Slovene Littoral and the western half of Inner Carniola , which had been annexed by Italy after World War One, were annexed to Slovenia. After
6825-485: The regime was mostly limited to intellectual and literary circles and became especially vocal after Tito's death in 1980 when the economic and political situation in Yugoslavia became very strained. Political disputes around economic measures were echoed in the public sentiment, as many Slovenians felt they were being economically exploited, having to sustain an expensive and inefficient federal administration. In 1987
6916-642: The rule of the neighboring states—Italy, Austria, and Hungary—were subjected to assimilation . Slovenia was the only present-day European nation that was trisected and completely annexed into both Nazi Germany and Fascist Italy during World War II. In addition, the Prekmurje region in the east was annexed to Hungary, and some villages in the Lower Sava Valley were incorporated in the newly created Nazi puppet Independent State of Croatia (NDH). Axis forces invaded Yugoslavia in April 1941 and defeated
7007-707: The same period Carniola , too, came under the Franks, and was Christianised from Aquileia . Following the anti-Frankish rebellion of Liudewit at the beginning of the 9th century, the Franks removed the Carantanian princes, replacing them with their own border dukes. Consequently, the Frankish feudal system reached the Slovene territory. After the victory of Emperor Otto I over the Magyars in 955, Slovene territory
7098-707: The same time, the ethnic Germans in the Gottschee enclave in the Italian annexation zone were resettled to the Nazi-controlled areas cleansed of their Slovene population. Around 30,000 to 40,000 Slovene men were drafted to the German Army and sent to the Eastern front. Slovene was banned from education, and its use in public life was limited. In south-central Slovenia, annexed by Fascist Italy and renamed
7189-526: The southern part of the duchies of Carinthia and Styria , the northern and eastern areas of the Austrian Littoral , as well as Prekmurje in the Kingdom of Hungary . Industrialization was accompanied by construction of railroads to link cities and markets, but the urbanization was limited. Due to limited opportunities, between 1880 and 1910 there was extensive emigration; around 300,000 Slovenes (1 in 6) emigrated to other countries, mostly to
7280-453: The structure. Stochastic expresses the fact that signals to be taken resemble random noise, which was called "Schottky noise" when first encountered in vacuum tubes. Without van der Meer's technique, UA1 would never have had the sufficient high-intensity anti-protons it needed. Without Rubbia's realisation of its usefulness, stochastic cooling would have been the subject of a few publications and nothing else. Simon van de Meer developed and tested
7371-675: The techniques needed later for the discovery of more exotic particles in a different type of particle collider. In 1976, he suggested adapting CERN's Super Proton Synchrotron (SPS) to collide protons and antiprotons in the same ring – the Proton-Antiproton Collider . Using Simon van der Meers technology of stochastic cooling , the Antiproton Accumulator was also built. The collider started running in 1981 and, in early 1983, an international team of more than 100 physicists headed by Rubbia and known as
7462-465: The technology in the proton Intersecting Storage Rings at CERN, but it is most effective on rather low-intensity beams, such as the anti-protons which were prepared for use in the SPS when configured as a collider. In 1970, Rubbia was appointed Higgins Professor of Physics at Harvard University , where he spent one semester per year for 18 years, while continuing his research activities at CERN. In 1989, he
7553-751: The transition period between the Bronze Age to the Iron Age , the Urnfield culture flourished. Archaeological remains dating from the Hallstatt period have been found, particularly in southeastern Slovenia, among them a number of situlas in Novo Mesto , the " Town of Situlas ". The area that is present-day Slovenia was in Roman times shared between Venetia et Histria (region X of Roman Italia in
7644-657: The twelve Battles of the Isonzo , which took place in present-day Slovenia's western border area with Italy. Hundreds of thousands of Slovene conscripts were drafted into the Austro-Hungarian Army , and over 30,000 of them died. Hundreds of thousands of Slovenes from Princely County of Gorizia and Gradisca were resettled in refugee camps in Italy and Austria. While the refugees in Austria received decent treatment,
7735-677: Was able to keep the County of Tyrol , while the Wittelsbach emperor Louis IV passed Carinthia and Carniolan march to the Habsburg duke Albert II of Austria , whose mother, Elisabeth of Carinthia is a sister of the late duke Henry of Gorizia . Therefore, most of the territory of present-day Slovenia became a hereditary land of the Habsburg monarchy . As with the other component parts of the Habsburg monarchy , Carinthia and Carniola remained
7826-600: Was appointed Director-General of the CERN Laboratory. During his mandate, in 1993, "CERN agreed to allow anybody to use the Web protocol and code free of charge … without any royalty or other constraint". Rubbia has also been one of the leaders in a collaboration effort deep in the Gran Sasso Laboratory , designed to detect any sign of decay of the proton. The experiment seeks evidence that would disprove
7917-705: Was appointed Scientific Director of the Institute for Advanced Sustainability Studies in Potsdam (Germany). He is a member of the Italy-USA Foundation . During his term as President of ENEA (1999–2005) he promoted a novel method for concentrating solar power at high temperatures for energy production, known as the Archimede Project , which is being developed by industry for commercial use. Marisa and Carlo Rubbia have two children. Rubbia
8008-683: Was divided into a number of border regions of the Holy Roman Empire . Carantania was elevated into the Duchy of Carinthia in 976. By the 11th century, the Germanization of what is now Lower Austria , effectively isolated the Slovene-inhabited territory from the other western Slavs , speeding up the development of the Slavs of Carantania and of Carniola into an independent Carantanian/Carniolans/Slovene ethnic group. By
8099-515: Was liberated by the partisan resistance and soon became a socialist federation known as the People's Federal Republic of Yugoslavia . The first Slovenian republic , named Federal Slovenia , was a constituent republic of the Yugoslavian federation, led by its own pro-Communist leadership. Approximately 8% of the Slovene population died during World War II . The small Jewish community, mostly in
8190-512: Was strongly industrialized. With further economic decentralization of Yugoslavia in 1965–66, Slovenia's domestic product was 2.5 times the average of Yugoslav republics. While a Communist country, after the Tito–Stalin split Yugoslavia initiated a period of military neutrality and non-alignment. JAT Yugoslav Airlines was the flag carrier and during its existence it grew to become one of the leading airlines in Europe both by fleet and destinations. By
8281-541: Was the first of a long series of experiments that Rubbia has performed in the field of weak interactions and which culminated in the Nobel Prize-winning work at CERN. He moved back to Europe for a placement at the University of Rome before joining the newly founded CERN in 1960, where he worked on experiments on the structure of weak interactions. CERN had just commissioned a new type of accelerator,
