A back-propagation (BP) neural network can solve complicated random nonlinear mapping problems; therefore, it can be applied to a wide range of problems. However, as the sample size increases, the time required to train BP neural networks becomes lengthy. Moreover, the classification accuracy decreases as well. To improve the classification accuracy and runtime efficiency of the BP neural netwo...
CVD diamond particle detectors are already in use in the CERN experiments ATLAS, CMS, LHCb and ALICE and at various particle accelerator laboratories in USA and Japan. This is a proven technology with high radiation tolerance and very fast signal read-out [1]. It can be used for measuring single-particles as well as for high-intensity particle cascades, for timing measurements on the nanosecond...
T he search for physics beyond the standard model—our current best description of fundamental particles and the interactions between them—is a top priority at high-energy particle accelerators. But researchers are also searching for new physics in the “low-energy” environment of the nucleus through a process known as neutrinoless double-beta (0νββ) decay. This hypothetical decay would show that...
As a nuclear track detector, CR-39 (polyallyl diglycol carbonate) is used to reveal the products of fusion reactions. Positioned around the OMEGA target chamber, pieces of CR-39 absorb and are damaged by ejected particles. The plastic is then etched in NaOH solution at 80°C for 6 hours, resulting in the formation of nuclear tracks visible under a digital microscope. The etching process also rev...
In a series of three papers. we attempt to evaluate the past scientific performance of the three main particle accelerators at the Geneva-based European Organjzation for Nuclear Research (CERN) over the period since 1960. and to assess the future prospects for CERN and its users during the next ten to fifteen years. We concerned ourselves in the first paper (Paper 1 Martin and Irvine [29]) with...
The concept of a compact ion particle accelerator has become attractive in view of recent progress in laserdriven ion acceleration. We report here the recent progress in the laser-driven proton beam transport at the Photo Medical Research Center (PMRC) at JAEA, which is established to address the challenge of laser-driven ion accelerator development for ion beam cancer therapy.
