(Pic du Midi + Chalcataya data) 1948 – Ar,ficial produc,on of pions by LaLes and Gardner at Berkeley Laboratory. 1949 – FoundaFon of CBPF by LaLes, Leite Lopes and Jayme Tiomno. 1962 – Start of the Brazil-‐Japan Collabora,on in Cosmic Rays at Chalcataya, Bolivia, proposed by Yukawa (5,200 m). 1970’s – Discovery of the exoFc Centauro events by the Brazil-‐Japan collaboraFon. Experimental High Energy Physics in LA: Pre-‐history: centered in Cosmic Ray Physics Argen,na: 1945 – Study of the intensity of cosmic rays at sea level. Variation with latitude due to the earth magnetic field. Kodak plate NTA exposed during 23 days on “El Condor” - Pampa de Achala Córdoba province (2108 m). 1949 – Creation of a group at Universidad de Buenos Aires headed by Estrella Mathov to study cosmic rays. 1950 – Measurements at Aconcagua Plaza de Mulas at 4325 m 1952 – Creation of Laboratorio de Placas Nucleares (CNEA) Mexico: First Steps with Manuel Sandoval Vallarta. 1932– Study of effects of geomagne,c field on cosmic rays. Collabora,on with Geoge Lemaitre. 1934 – Crea,on at UNAM of a group to study Cosmic Rays lead by Sandoval Vallarta. 1954 – Instala,on of Solar Neutron Telescope in Sierra Negra 1958 – New group organized by Ruth Gall at the Ins,tute of Geophysics 80’s: New revival of HEP in La,n America: Par,cle Accelerators: 1982: “1st Panamerican Symposium on Par,cle Physics and Technology” held at Cocoyot in Mexico: Leon Lederman FERMILAB Director invites La,n American physicists to par,cipate in experiments at Fermilab. about 50 a_endees from Europe, North America, and La,n America; these included Lederman, M. Moshinsky, C. Avilez, M. Moreno, A. Zepeda, J. Flores, J. Tiomno, S. Glashow, J. Bjorken, B. Richter and G. Charpak. Clicerio Avilez decided to switch from theore,cal to experimental par,cle physics and to form the UNAM HEP group. Conference outcomes: -‐ four subsequent similar symposia over the next decade -‐ formal Fermilab program to aid La,n American physics (par,cularly par,cle physics); 80’s: New revival of HEP in La,n America: Par,cle Accelerators: 1983: 2nd Pan American Symposium in Rio de Janeiro organized by Jaime Tiomno and Moyses Nussenzweig : new offer and support for 4 physicists. 1984: Brazilian group of 4 physicists join experiment E691 of Charm photoproduc,on at Fermilab. Clicerio Avilez spent a year at Fermilab and joined experiment E766 of Hyperon produc,on at Brookaven and later E690 of strange/ charm produc,on. 1987: 3rd Pan American Symposium held in Rio, hosted by Leite Lopes, CBPF Director: 1989: 4th Pan American Symposium held in Bariloche, Argen,na, organized by Mario Mariscok. 1992: 5th Pan American Symposium held in Cartagena, Colombia, hosted by Eduardo Posada and led to the "Cartagena Manifesto”. 80’s: New revival of HEP in La,n America: Par,cle Accelerators: In 1984, through the collabora,on of NSF and DOE, FERMILAB made available a grant of $300,000 dollars designed to be used to assist Physics in the five na,ons with major physics ac,vity. This was to be spent in journal subscrip,ons, payment of publica,on charges, spare parts and maintenance items for exis,ng equipments and per diem support for urgent short trips by physicists to the US. Later another $150,000 was added to the grant. This made possible to con,nue the research ac,vi,es in spite of the severe foreign currency squeeze in La,n American countries at this ,me . 1987: Herwig Schopper, Director of CERN, and Carlo Rubia, following Lederman inicia,ve, invited La,n American physicists to join CERN experiments. In Brazil groups from CBPF and UFRJ joined the DELPHI experiment at LEP. L.A.

LBNF – LONG BASELINE NEUTRINO FACILITY Summary: Evolu,on of Research Ac,vi,es: Hardware Projects: 1st stage: IntegraFon in other groups with more experience and parFcipaFon in the construcFon of detectors, electronics and development of sovware 2nd stage: Responsibility for the construcFon and maintenance of detector systems: • Drix Chambers for SELEX (1993-‐1996) -‐ Embraer industry US$ 150,000 • PWC (Propor,onal wire Chambers) for E831/FOCUS (1996) US$ 40,000 • Roman Pots for DZERO (1998-‐2001) -‐ LNLS Laboratory US$ 400,000 • Surface detectors for AUGER Observatory -‐ Alpina industry US$ 1,000,000 • Ba_eries for Auger to backup solar pannels – Moura industry US$ 300,000 Event reconstruc,on: parFcipaFon in sovware development Data Analysis: 1st stage: integraFon in other groups doing data analysis 2nd stage: responsibility for analysis and papers Example: E791/cbpf group: 7 papers out of 34 ( more than 20%) Conclusions: -‐ In the last 30 years Fermilab has played a very important role in the development of High Energy Physics in La,n America. -‐ Lederman ini,a,ve and support made possible the crea,on of experimental high energy physics groups in Mexico, Argen,na, Brazil, Peru and Colombia developing a strong La,n American community of about 1,000 researchers, technicians and graduate students. -‐ This has allowed the condi,ons for a good La,n American par,cipa,on in the CERN LHC program. -‐ The construc,on of Neutrino Facili,es at Fermilab will increase again the La,n American par,cipa,on at the lab.
