Measurements of neutron fluxes from tokamak plasmas using a compact neutron spectrometer.

A compact neutron spectrometer based on the BC-501A liquid organic scintillator was applied to neutron measurements at the TUMAN-3M tokamak. The spectrometer was calibrated using measurements from the ion beam of the cyclotron accelerator. Neutron spectra were measured during discharges using a neutral deuterium beam injection into the TUMAN-3M D-plasma. An energy distribution of the neutrons from the plasma that hit the spectrometer was obtained from the measured BC-501A instrumental spectra by the DeGaSum code using detector response functions obtained in the course of the calibration. This allowed for the estimation of the 2.45 MeV neutron yield and the evaluation of both the time evolution of the DD fusion rate and the characteristic time of the injected deuterium slowing down in discharges with neutral beam injection heating.

Provide a block diagram of the set up and algorithm maintaining its work in different modes.

[Analysis of the reasons for the late detection of malignant tumors (based on data from the Voroshilovgrad Province Oncological Dispensary)]. / Analiz prichin nesvoevremennogo vyiavleniia zlokachestvennykh opukholei (po materialam Voroshilovgradskogo oblastnogo onkologicheskogo dispansesra).

The share of advanced malignant tumors is approximately 22.9%, the highest incidence rate (57.1%) being among patients aged 51--70 years. They show the following distribution for different sites: gastrointestinal tract--53.12; respiratory system--23.78; female genital organs--8.12; urinary system--6.13 and other sites--8.76%. Among the main causes of the detection of malignant tumors at advanced states are superficial, irregular check-ups, errors in clinical and roentgenologic diagnosis, latent course of the disease late application for medical aid and inadequate knowledge of oncology by general practitioners. With a view to improving the doctors' qualifications and raising the standards of mass screenings, Weeks of Oncologists are being conducted, short-term courses for advanced medical training and specialized oncological mass screenings for occupational tumors are organized; and Evening University of Oncology was established.
