Hadrontherapy is one of the most refined radiotherapic technique for tumours treatment. It uses hadrons, that is to say charged particles made up from quarks, as protons and ions. These particles, contrary to what occurs in radiotherapy, can be directed with precision against the tumour mass, with minimum risks to hit vital organs and surrounding healthy tissues. In particular ions have a higher radiobiological effect: they can hit in fact deep tumours, for this reason they are particular indicated for radioresistent tumours, such as cerebral tumours, the ones of the head-neck area and lung and pancreas carcinoma. Therapy with protons is instead indicated for tumours located near organs at risk, such as eye, head base, or along the backbone, because they allow to direct the beam form in a more refined way.
Up today the only instruments able to produce protons and ions as well for hadrontherapy are synchrotrons: accelerators machines, much more complex, bulkier and expensive than cyclotrons. A synchrotron consists indeed of a ring with a diameter of at least 25 metres, while a cyclotron is a compact instrument with a diameter of 5 metres and with a considerably lower cost. In the context of its studies for the development of new syncrotrons, Infn has worked for the development of a multiparticle cyclotron, able to provide protons and carbon ions with the energy required for hadrontherapic treatments. "The new cyclotron offers a great technological advantage. Thanks to it, for the first time a doctor will have the opportunity to choose to produce ions or protons, according to the kind of tumour, with a compact, easily to manage and decidedly cheaper instrument than the traditional one. With the ions produced by this new machine, it will possible to treat tumours at a maximum depth of 18 centimetres", explain Giacomo Cuttone and Luciano Calabretta of Infn Southern National Laboratories.
There are in the world several centres for hadrontherapy, most of all in Japan and in the United States. In Italy there is the sperimental project Catana (Hadrontherapy Centre and Advanced Nuclear Applications). Started at the Infn Southern National Laboratories in cooperation with Catania University, Catana is dedicated to the treatment with protons of eye tumour (up today the treated patients are 112). Concerning hadrontherapy with ions, there are in Europe two structures under construction: one is the Heidelberg University clinic, in Germany, the other is the National Centre of Hadrontherapy that will rise in Pavia, from the collaboration between the Cnao foundation and Infn.
The new cyclotron developed by Infn and realized by Iba will be able to enrich the therapeutic power of hadrontherapy centres.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
