“…The Standard Model predicts its branching ratio to be B(K 0 L → π 0 νν) = (2.43 ± 0.39) × 10 −11 [34]. This decay is an important source of information on higher-order effects in electroweak interactions, and therefore can serve as a probe of physics beyond the Standard Model (see [35] and references therein). Figure 9: Differential cross-section for the production of K 0 L as a function of the incident proton momentum [35].…”

“…Of particular interest is the unitarity triangle parameter sin 2β, which can also be determined from the decay B d → ΨK s . Both determinations of this parameter have to coincide if the Standard Model is valid [35].…”

The main "bottleneck" limiting the beam power in circular machines is caused by space charge effects that produce beam instabilities. To increase maximally the beam power of a "proton driver", it is proposed to build a facility consisting solely of a 2.5 GeV injector linac (PI) and a 20 GeV pulsed superconducting linac (SCL). Such a facility could be constructed using the existing KEK accelerator infrastructure. The PI, based on the European Spallation Source (ESS) linac, would serve both as an injector to the SCL and a source of proton beams that could be used to copiously produce, e.g., muons and "cold" neutrons. Protons accelerated by the SCL would be transferred through the KEK Tristan ring in order to create neutrino, kaon and muon beams for fixed-target experiments. At a later stage, a 70 GeV proton synchrotron could be installed inside the Tristan ring. The SCL, comprising 1.3 GHz ILC-type rf cavities, could also accelerate polarized or unpolarized electron beams. After acceleration, electrons could be used to produce polarized positrons, or may traverse an XFEL undulator.

“…We found [10,11] that actinides can be determined with a fairly high sensitivity using analytical mass spectrometers commercially manufactured in Ukraine and Russia provided that their ion recording system is improved without affecting the ion-optical scheme of the mass analyzer. Modernization consists in changing from a standard single-slot to a position-sensitive ion detector (PSID) comprising two microchannel plates and an anode system fixing the coordinates of the centroid of the electron avalanche caused by each individual ion.…”

“…Using a large number of samples (over 200) taken in 199932003, we estimated the sensitivity of analysis S for each of the above-mentioned types of measurement [10]. For example, for real samples containing 0.13 10 pg of Pu S was estimated at 1.0 0 10 5 pulse pg 31 + 60%.…”

A procedure was developed for isolation and determination of the isotope composition and content of U and Pu on the ultrasmall level in environmental samples of technogenic origin, characterized by a small mass (up to 0.l g) and complex macrocomposition. The procedure is based on isotope dilution and mass-spectrometric measurement of the isotope ratios (IDMS). Subnanogram quantities of U and Pu were isolated using a modification of resin bead technique, involving sorption on a limited number of anion exchanger beads and allowing, after desorption, analysis of the solutions containing the selectively isolated nanogram quantities of U or 10 312 310 315 g of Pu. The measurements were carried out on thermal ionization mass spectrometers manufactured in Ukraine and Russia with a modernized ion registration system utilizing a position-sensitive detector based on microchannel plates. Uranium was analyzed by the laser luminescence method suitable for measuring fractions of nanograms of U accurately to within 10%. This procedure, combining highly sensitive methods of isolation of ultrasmall quantities of U and Pu with the mass-spectrometric method of analysis, is applied at the Radium Institute (acting as a national laboratory of IAEA) and at the Institute of Analytical Instrument Designing, Russian Academy of Sciences, in analysis of inspection samples submitted by IAEA for monitoring the activity of nuclear facilities under the Treaty on Nonproliferation of Nuclear Weapons.
