Treating Cancer with Proton Therapy Information for Patients and Family Members Professor Dr
Treating Cancer with Proton Therapy Information for patients and family members Professor Dr. med. Damien Charles Weber, Dear readers Head and Chairman, Proton therapy is a special kind of radiation therapy. For many years now, patients Centre for Proton Therapy suffering from certain tumour diseases have successfully undergone proton radi- ation therapy at the Paul Scherrer Institute’s Centre for Proton Therapy. This brochure is intended to give a more detailed explanation of how proton ther- apy works and provide practical information on the treatment we offer at our facil- ity. We will include a step-by-step description of the way in which we treat deep- seated tumours. We will not deal with the treatment of eye tumours in this brochure. If you have further questions on the proton therapy carried out at the Paul Scherrer Institute, please do not hesitate to address these by getting in touch with our secretaries.

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. -
The Physical Tourist Physics and New York City
Phys. perspect. 5 (2003) 87–121 © Birkha¨user Verlag, Basel, 2003 1422–6944/05/010087–35 The Physical Tourist Physics and New York City Benjamin Bederson* I discuss the contributions of physicists who have lived and worked in New York City within the context of the high schools, colleges, universities, and other institutions with which they were and are associated. I close with a walking tour of major sites of interest in Manhattan. Key words: Thomas A. Edison; Nikola Tesla; Michael I.

Introduction When I was approached by the editors of Physics in Perspecti6e to prepare an article on New York City for The Physical Tourist section, I was happy to do so. I have been a New Yorker all my life, except for short-term stays elsewhere on sabbatical leaves and other visits. My professional life developed in New York, and I married and raised my family in New York and its environs. Accordingly, writing such an article seemed a natural thing to do. About halfway through its preparation, however, the attack on the World Trade Center took place. -
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. -

The Second Lepton Family Klaus Winter, CERN The Nobel Prize for Physics for 1988 was awarded to L. Lederman, M. Schwartz and J. Steinberger for work on neutrinos in the early 1960s. In a letter [1] addressed to the "dear radioactive ladies and gentlemen", writ ten in December 1930, Wolfgang Pauli proposed, as a "desperate remedy" to save the principle of conservation of energy in beta-decay, the idea of the neutrino, a neutral particle of spin 1/2 and with a mass not larger than 0.01 proton mass. "The continuous beta-spectrum [2] would then become understandable by the assumption that in beta-decay a neutrino is emitted together with the electron, in such a way that the sum of the energies of the neutrino and electron is constant." Pauli did not specify at that time Fig. 1 — A recent photograph taken at CERN of Leon Lederman (left), whether the neutrino was to be ejected Jack Steinberger (centre) and Melvin Schwartz. or created. In his famous paper "An attempt of a theory of beta-decay" [3] the muon not decay into e + at the rate ween 1 and 2 GeV should be achievable. E. Fermi used the neutrino concept of predicted if such a non-locality exis Would these synchrotrons though, deli Pauli together with the concept of the ted ? ". On this view the muon would vir ver enough neutrinos? According to nucleon of Heisenberg. He assumed tually dissociate into W + v, the charged their specifications they should accele that in beta-decay a pair comprising an W would radiate a and W + v would rate 1011 protons per second, an unpre electron and a neutrino is created, analo recombine to an electron. -
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. -
