Wie Es Zur Gründung Des Instituts Für Hochenergiephysik Kam
HEPHY-PUB-997 24 Nov. 2016 (rev. 19 Sep. 2017) Wie es zur Gründung des Instituts für Hochenergiephysik kam Winfried A. Mitaroff Institut für Hochenergiephysik der ÖAW, Wien ∗ Zusammenfassung Nach dem Beitritt Österreichs zur Europäischen Organisation für Kernforschung (CERN) im Jahr 1959 und bescheidenen Anfängen an der Universität Wien wurde 1966 mit der Gründung des Instituts für Hochenergiephysik (HEPHY) durch die Österreichische Akademie der Wissenschaften (ÖAW) der Grundlagenforschung auf dem Gebiet der experimentellen Teilchenphysik in unserem Land eine solide Entwicklungsmöglichkeit eröffnet. In den seither vergangenen 50 Jahren war das Institut im Rahmen internationaler Kollaborationen an einer Vielzahl von Experimenten an Großforschungsanlagen (vorwiegend, aber nicht ausschließlich, bei CERN) beteiligt – darunter auch an so bedeutenden, welche später zu Physik-Nobelpreisen geführt haben. Hierzu hat es wichtige Beiträge geleistet, insbesondere in den Bereichen Detektorentwicklung, Datenanalyse und Phänomenologie. Die vorliegende Studie zielt auf die Vorgeschichte, welche schließlich zur Institutsgründung führte. Als Quellen dienten Sitzungsprotokolle und Tätigkeitsberichte, Institutsbroschüren, Autobiografien, sowie persönliche Erinnerungen. Dieser Artikel stellt den ersten Teil eines Beitrags zur Monografie “175 Jahre Österreichische Akademie der Wissenschaften” (Wien 2022) dar, welcher die wissenschaftliche Institutsgeschichte bis zur Gegenwart beschreiben wird. 1 Einleitung Die Hochenergiephysik als selbständige Wissenschaftsdisziplin -
Willibald Jentschke –
European organization for nuclear research Willibald Jentschke – Willibald Jentschke founder of DESY and former Director"General of CERN passed away on March + on 18 December 1959. Jentschke became its first director and remained in this position until 1970. Jentschke served as Director-General of CERN Laboratory I – the original Meyrin site – from 1971–75. During the same period, John Adams was Director-General of the neighbouring Laboratory II, where the new SPS pro- ton synchrotron was being construct- ed. Having two Directors-General was an unusual and delicate situation, but to their eternal credit Jentschke and Adams handled it well. Jentschke oversaw the exploitation of important new investments, including an ambi- tious research programme for neutri- no physics. In 1973, this effort enabled physicists to discover the neutral cur- rents of the weak interaction. Faced with a major discovery, CERN was nervous. However, Jentschke ensured that the result went on record as one Born in Vienna, Willibald Jentschke of the Laboratory’s great achieve- obtained his Ph.D. in nuclear physics ments. at the age of 24.

Prospects of Measuring the Branching Fraction of the Higgs Boson
ILD-PHYS-2020-002 09 September 2020 Prospects of measuring the branching fraction of the Higgs boson decaying into muon pairs at the International Linear Collider Shin-ichi Kawada∗, Jenny List∗, Mikael Berggren∗ ∗ DESY, Notkestraße 85, 22607 Hamburg, Germany Abstract The prospects for measuring the branching fraction of H µ+µ at the International → − Linear Collider (ILC) have been evaluated based on a full detector simulation of the Interna- tional Large Detector (ILD) concept, considering centre-of-mass energies (√s) of 250 GeV + + and 500 GeV. For both √s cases, the two final states e e− qqH and e e− ννH 1 → → 1 have been analyzed. For integrated luminosities of 2 ab− at √s = 250 GeV and 4 ab− at √s = 500 GeV, the combined precision on the branching fraction of H µ+µ is estim- → − ated to be 17%. The impact of the transverse momentum resolution for this analysis is also studied∗. arXiv:2009.04340v1 [hep-ex] 9 Sep 2020 ∗This work was carried out in the framework of the ILD concept group 1 Introduction 1 Introduction A Standard Model (SM)-like Higgs boson with mass of 125 GeV has been discovered by the ATLAS ∼ and CMS experiments at the Large Hadron Collider (LHC) [1, 2]. Recently, the decay mode of the Higgs boson to bottom quarks H bb has been observed at the LHC [3, 4], as well as the ttH production → process [5, 6], both being consistent with the SM prediction. However, there are several important questions to which the SM does not offer an answer: it neither explains the hierarchy problem, nor does it address the nature of dark matter, the origin of cosmic inflation, or the baryon-antibaryon asymmetry in the universe. -

The Radiological Situation in the Beam-Cleaning Sections of the CERN Large Hadron Collider (LHC) I I CHAPTER 5 Benchmark Measurements
Markus Brugger The Radiological Situation in the Beam-Cleaning Sections of the CERN Large Hadron Collider (LHC) DISSERTATION zur Erlangung des akademischen Grades eines Doktors der Technischen Wissenschaften eingereicht an der Technischen Universität Graz Rechbauerstraße 12 A - 8010 Graz CERN-THESIS-2003-039 //2003 Begutachter: Ao.Univ.-Prof. Dr.techn. Ewald Schachinger Institut fur Theoretische Physik der TU Graz Graz, November 2003 Kurzfassung Diese Dissertation beschäftigt sich mit radiologischen Aspekten am "Large Hadron Collider", welcher momentan am CERN gebaut wird. Im Detail handelt es sich dabei um die beiden so genannten "Beam Cleaning Insertions", jene Bereiche in welchen man versucht möglichst alle Teilchen zu absorbieren, welche ansonsten in anderen Teilen des Beschleunigers zu Schäden führen könnten. Es werden zwei kritische Aspekte des Strahlenschutzes behandelt: Dosisleistung durch induzierte Radioaktivität und die Aktivierung von Luft. Die Anpassung des Designs dieser Regionen in Verbindung mit einer detaillierten Abschätzung der jeweiligen Dosisleistungen ist von großer Wichtigkeit für spätere Wartungsarbeiten. Bisher standen lediglich sehr eingeschränkte Studien über die in jenen Regionen zu erwartenden Strahlenniveaus zur Verfügung, welche diese Dissertation nun zu erweitern und vervollständigen sucht. Dabei wird eine neue Methode angewendet um Dosisleistungen zu bestimmen, welche, da sie zum ersten Mal zu deren Berechnung verwendet wird, sorgfältig im Rahmen eines Experimentes überprüft wird. Zusätzlich stellt die Aktivierung der Luft einen wichtigen Aspekt für die Inbetriebnahme des Beschleunigers dar. Jüngste Änderungen im Konzept des Beschleunigers, machen eine Revision vorhandener Ergebnisse und eine umfassende neue Studie notwendig. Die Ergebnisse von beiden Studien sind von großer Wichtigkeit für die weiteren Entscheidungen bezüglich des endgültigen Entwurfs der "Beam Cleaning Insertions". -
