A prototype of a 2D detector based on specially designed straw tubes with cathode data readout has been developed and tested. This detector exhibits comparable accuracies in measuring radial and ...longitudinal coordinates. Its rate capability is similar to the capabilities of traditional detectors whose tubes are smaller by half in diameter.

Precise measurement of straw axial coordinate (along the anode wire) with accuracy compatible with straw radial coordinate determination by drift time measurement and increase of straw detector rate ...capability by using straw cathode readout instead of anode readout are presented.
Detector rate capability is one of the main parameters for designing a new detector for high energy physics due to the permanent rise of the beam luminosity of modern accelerators. One of the widely ...used detectors for particle track reconstruction is a straw-detector based on drift tubes. The rate capability of such detectors is limited by the parameters of readout electronics. The traditional method of increasing detector rate capability consists in increasing their granularity (the number of “elementary” detectors = readout channels) by reducing the straw diameter and/or by dividing the straw anode wire into two parts (for decreasing the rate per readout channel). A new method of designing straw detectors with a high rate capability is presented and tested. The method is based on dividing the straw cathode into parts and the independent readout of each part.

(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image).A search for dark matter and unparticle production at the LHC has been performed using events containing two charged ...leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum. This study is based on data collected with the CMS detector in 2015, corresponding to an integrated luminosity of 2.3 fb super(-1) of proton-proton collisions at the LHC, at a center-of-mass energy of 13 TeV. No excess over the standard model expectation is observed. Compared to previous searches in this topology, which exclusively relied on effective field theories, the results are interpreted in terms of a simplified model of dark matter production for both vector and axial vector couplings between a mediator and dark matter particles. The first study of this class of models using CMS data at ... TeV is presented. Additionally, effective field theories of dark matter and unparticle production are used to interpret the data.

Nuclear and radiation safety remains one of the most important components of the national security of our country. The increasing requirements for the medical care system in the Armed Forces of the ...Russian Federation in case of peacetime acute radiation injuries are due to the impossibility of completely eliminating the risks of radiation emergencies as a result of natural disasters, industrial radiation accidents and the threat of nuclear terrorism. The peacetime three-level system of medical support in the Armed Forces of the Russian Federation has been developed. It is designed to guarantee the first aid, primary predoctor care, primary doctor care and primary specialized health care for victims of acute radiation injuries by medical units, formations and organizations in the territorial zone of responsibility. In 2017 it was completed a research work "Improving the organization of therapeutic care in acute radiation injuries at the stages of medical evacuation in radiation accidents". An analysis of medical service capabilities to provide specialized, high-tech medical care in radiation injuries showed the relevance of the clinical base development in military medical organizations and the importance of interaction with radiological medical centers of other ministries, agencies and services. The solution of these tasks will be facilitated by the creation of a specialized infrastructure on the basis of military medical organizations of the district (fleet), which is providing necessary conditions for the provision of medical assistance to victims of the radiation emergency.
