Light proton-rich bound and unbound nuclei were produced by means of stripping reactions of secondary beams of Mg and Ne. The decays of the unbound nuclei Na have been measured by detecting their decay products Ne and one proton and by performing an invariant-mass reconstruction. For Na, the present work is the first measurement of its decay. As the decay scheme of this nucleus could not be det...

The demand for clinical use of accelerated heavy chargedparticle (proton and light-ion) beams for cancer treatment is now burgeoning worldwide. Clinical trials are underway at more than a dozen accelerators. Several hospital-based accelerator facilities dedicated to radiation treatment of human cancer have been constructed, and their number is growing. Many instruments in medical systems have b...

This paper studies the specific features of energy and angular distribution of protons accelerated by high intensity ultrashort laser pulse from a dense target. Production and acceleration of particle beams by ultrashort laser pulses with light intensities of order of 10 W/cm and higher is interesting both from the theoretical point of view and for practical applications, e.g., development of c...

The physical properties of particles used in radiation therapy, such as protons, have been well characterized, and their dose distributions are superior to photon-based treatments. However, proton therapy may also have inherent biologic advantages that have not been capitalized on. Unlike photon beams, the linear energy transfer (LET) and hence biologic effectiveness of particle beams varies al...

The PP2PP experiment is devoted to the proton – proton elastic scattering measurements at the Relativistic Heavy Ion Collider (RHIC) at the centre-of-mass energies 50 ≤ √ s ≤ 500 GeV and the four-momentum transfer 0.0004 ≤ |t| ≤ 1.3 GeV. The option of polarized proton beams offers a unique possibility to investigate the spin dependence of the proton elastic scattering in a systematic way. The e...

Intense low energy muon beams – as part of a muon collider complex – may become available for use in radiotherapy. It is of interest to compare their effectiveness in this application with that of hadron beams in a setting where processes common to these beams are treated exactly alike. Detailed simulations of physics processes for muon, proton, antiproton, neutron, kaon and pion beams stopping...

As is clear from the varied contributions to this workshop concerned with ongoing work on HERA data, much is still being learned from the world’s first electron proton (ep) collider [ 1]. Measurements based on the final HERA data remain of high importance for the physics of strong interactions and proton structure in general and in particular for applications at the LHC [ 2]. By now, our unders...

We experimentally evaluated the proton beam dose reproducibility, sensitivity, angular dependence and depth-dose relationships for a new Metal Oxide Semiconductor Field Effect Transistor (MOSFET) detector. The detector was fabricated with a thinner oxide layer and was operated at high-bias voltages. In order to accurately measure dose distributions, we developed a practical method for correctin...
