    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.

  • Targeted Radiotherapeutics from 'Bench-To-Bedside'
    RadiochemistRy in switzeRland CHIMIA 2020, 74, No. 12 939 doi:10.2533/chimia.2020.939 Chimia 74 (2020) 939–945 © C. Müller, M. Béhé, S. Geistlich, N. P. van der Meulen, R. 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.

  • First Operation of the Ultracold Neutron Source at the Paul Scherrer Institute
    First operation of the ultracold neutron source at the Paul Scherrer Institute The UCN source team has demonstrated excellent functioning of all major subsystems of the new facility. Ultracold neutrons have been produced for the first time from this source and under full load. The performance was found as expected under the operational conditions. The construction of the PSI source for ultracold neutrons (UCN) has been completed. The new UCN source is the second spallation target station driven by the PSI ring cyclotron and designed to take macro-pulses of up to 8s of the full proton beam intensity (590MeV, >2mA). Neutrons are thermalized in a heavy water moderator, cooled down and converted to UCN in solid deuterium. The license to start full commissioning arrived on December 16. Between December 16 and 22, the source has been operated with the aim and duty to demonstrate the principle functioning of all major subsystems. Different modes of operation have been tested starting with 5ms short pulses ramping from 100µA to 1.8mA (operational limit of the accelerator at the time of testing), followed by continuous 10µA beam for mapping of the radiation field and dose rates around the biological shielding, especially in the experimental areas, and finally going to longer pulses starting from 500µA for 2s up to 1.8mA for 8s. The test of the whole accelerator chain and beam diagnostics was very successful and the desired pulses were reliably delivered. Long intense pulses of the 1MW beam always had 5ms pilot pulses running a few seconds ahead and guaranteeing the perfect adjustment of the proton beamline.

  • Research at the Paul Scherrer Institut
    390 FR9807042 Research at the Paul Scherrer Institut H. K. 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.
