    THE CANTON OF AARGAU: ECONOMY AND EMPLOYMENT The Canton of Aargau is situated in Switzerland’s strongest economic area. Some 340 000 people are employed here in around 40 000 companies. An above-average proportion of these workers are active in the field of research and development. In fact, this is more than twice the national average. Our economic, tax and financial policies make the Canton of Aargau an attractive place of business for international corporations as well as for small and medium-sized businesses. The innovative Robotec Solutions AG known as a leading enterprise in robot applications. Standard & Poor’s has awarded the Canton of Aargau the rating AA+. And it’s no wonder. After all, we have a low unemployment rate, a moderate taxation rate, a strong economy and a high standard of living. These factors appeal to many well-known companies operating here in a wide range of industries – including ABB, GE, Franke, Syngenta and Roche. Our media landscape is equally diverse. In addition to AZ Medien, the canton boasts numerous other well-positioned local media companies. THE CANTON OF AARGAU: LIFE AND LIVING SINA SINGER The Canton of Aargau is currently home to some 670 000 people. That makes us the fourth-largest canton in Switzerland. Aargau is an urban area, yet also modest in size. The Canton of Aargau is within reasonable distance of anywhere – whether by car or public transport. However, for those who prefer to stay and be part of the local scene, Aargau has well-established communities and a wealth of vibrant traditions.

    Particle Accelerator Activities at the Paul Scherrer Institut

    PSI Bericht Nr. 17-07 December 2017 Particle Accelerator Activities at the Paul Scherrer Institut Terence GARVEY Paul Scherrer Institut, Villigen, Switzerland 5232 Division of Large Research Infrastructures Invited paper presented at Les Journées Accélérateurs de la Société Française de Physique, Roscoff, 3rd – 6th October, 2017. Resumé Les Activités Accélérateur à l’Institut Paul Scherrer. L'Institut Paul Scherrer exploite deux complexes d'accélérateurs en tant que ‘centre- serveurs’ pour une grande communauté de chercheurs. Il s'agit de l'Accélérateur de Protons à Haute Intensité (HIPA) et de la Source de Lumière Suisse (SLS). HIPA est un cyclotron à protons de 590 MeV. Il sert à produire des neutrons par spallation pour la recherche en physique de la matière condensée et à produire des muons et d'autres particules secondaires pour la recherche en magnétisme et en physique des particules. Le SLS est un anneau de stockage d’électrons de 2,4 GeV utilisé comme source de rayonnement synchrotron de 3ème génération fournissant des photons pour une large gamme de disciplines scientifiques. En plus de ces deux installations, l'Institut met progressivement en service un laser à électrons libres en rayons X (SwissFEL) qui fournira aux chercheurs des impulsions femto-seconde intenses à partir d’une ligne de rayons X ‘dur’ (ARAMIS) et de rayons X ‘mou’ (ATHOS). L'Institut exploite également un cyclotron supraconductrice à 250 MeV (COMET) aux fins de la thérapie par proton. Le centre de thérapie a récemment été équipé d'un troisième « gantry » rotatif qui est en cours de mise en service. Un « upgrade » du système de radiofréquence de HIPA et des projets pour "SLS-2" seront présentés.

    1 After Dinner Speech by Dr. Josef Rembser CERN, Geneva 14 September 2009 Celebration in honour of Professor Herwig Schopper’s 85 th Birthday I. Dear Friends, honourable, dear Professor Schopper! On 28 February of this year, you celebrated your 85th Birthday. This evening we are looking back on this memorable date, wishing you many happy returns of the day. You have been blessed with a life full of harmony and accomplishments, always keeping young physically and intellectually. This is a special blessing granted to a person: Love and family, friendships and encounters, giving and receiving, working and achieving acknowledgements and honours in a fulfilling profession and in challenging missions. Tomorrow, a scientific Colloquium will honour you as researcher and scientific teacher . Today, on the eve of the colloquium, I would like to speak about Herwig Schopper as a research politician and a research manager . My personal remarks and remembrances will focus, dear Herwig Schopper, on the guiding contributions you made in shaping, promoting and advancing science and research and their relevant policies in Germany and in Europe. 2 Professor Heuer, I am grateful for your invitation. It is a pleasure for me to give today's After-Dinner speech in honour of our jubilee. For many years during my service in the German Ministry of Research and Technology (BMFT) in Bonn I had close personal and professional connections with you, dear Professor Schopper, regarding German science and research policy including CERN. II. In 1945, with the end of the 2 nd World War, Germany as guilty party and loser plunged the world and its own country into destruction and suffering, thus experiencing a historical catastrophe.

Schibli Targeted Radiotherapeutics from ‘Bench-to-Bedside’ Cristina Müllera, Martin Béhéa, Susanne Geistlicha, Nicholas P. van der Meulenab, and Roger Schibli*ac Abstract: The concept of targeted radionuclide therapy (TRT) is the accurate and efficient delivery of radiation to disseminated cancer lesions while minimizing damage to healthy tissue and organs. Critical aspects for success- ful development of novel radiopharmaceuticals for TRT are: i) the identification and characterization of suitable targets expressed on cancer cells; ii) the selection of chemical or biological molecules which exhibit high affin- ity and selectivity for the cancer cell-associated target; iii) the selection of a radionuclide with decay properties that suit the properties of the targeting molecule and the clinical purpose. The Center for Radiopharmaceutical Sciences (CRS) at the Paul Scherrer Institute in Switzerland is privileged to be situated close to unique infrastruc- ture for radionuclide production (high energy accelerators and a neutron source) and access to C/B-type labora- tories including preclinical, nuclear imaging equipment and Swissmedic-certified laboratories for the preparation of drug samples for human use. These favorable circumstances allow production of non-standard radionuclides, exploring their biochemical and pharmacological features and effects for tumor therapy and diagnosis, while investigating and characterizing new targeting structures and optimizing these aspects for translational research on radiopharmaceuticals. In close collaboration with various clinical partners in Switzerland, the most promising candidates are translated to clinics for ‘first-in-human’ studies.

B. How did your interest in physics arise? You enrolled in the late 1950s, when the period of post-war reconstruction of physics in Europe was coming to an end, and Italy was entering into a phase of great expansion. Those were very exciting years. It was the beginning of the space era. L. M. The beginning of the space era certainly had a strong influence on many people, absolutely. The landing on the moon in 1969 was for sure unforgettable, but at that time I was already working in Physics and about to get married. My interest in physics started well before. The real beginning was around 1955. Most important for me was astronomy. It is not surprising that astronomy marked for many people the beginning of their interest in science.

Walter Paul Scherrer Institut, PSI - West, CH- 5232 ViUigen, Switzerland Abstract The Paul Scherrer Institut (PSI) is a multidisciplinary research institute for natural sciences and technology. In national and international collaboration with universities, other research institutes and industry, PSI is active in elementary particle physics, life sciences, solid-state physics, material sciences, nuclear and non-nuclear energy research, and energy-related ecology. PSI's priorities lie in research fields which are relevant to sustainable development, serve educational needs and are beyond the possibilities of a single university department. PSI develops and operates complex research installations open to a national and international scientific community. With the upgrade of the 590 MeV Ring accelerator PSI disposes of the world's most powerful cyclotron, allowing to operate high intensity secondary pion and muon beams, a neutron spallation source and various applications in medicine and materials research. A short review on research at PSI is presented, with special concentration on particle physics experiments.

The heritage of these centers survives in their physical structures and instruments; in the scientific data recorded in their observing logs, photographic plates, and instrumental records of various kinds; and more commonly in the published and unpublished records of astronomers and of the observatories at which they worked. These records have continuing value for both historical and scientific research. In January 2007 the American Astronomical Society (AAS) formed a working group to develop and disseminate procedures, criteria, and priorities for identifying, designating, and preserving structures, instruments, and records so that they will continue to be available for astronomical and historical research, for the teaching of astronomy, and for outreach to the general public. The scope of this charge is quite broad, encompassing astronomical structures ranging from archaeoastronomical sites to modern observatories; papers of individual astronomers, observatories and professional journals; observing records; and astronomical instruments themselves. Reflecting this wide scope, the members of the working group include historians of astronomy, practicing astronomers and observatory directors, and specialists Oak Ridge National Laboratory; Santa encounters tight security during in astronomical instruments, archives, and archaeology. a wartime visit to Oak Ridge.
