Software for the on-off-line A-A-T coincidence experiment with use of semiconductor detector of nuclear radiation

Full text: In γ-spectra measurements with 200 cm3 HPGe-detector with energy resolution (FWHM) of 3.5 keV for α-rays 1.33 MeV 60Co, 60 cm3 Ge(Li)-detector with energy resolution of 1.9 keV for γ -rays 1.33 MeV 60Co, 2 cm3 HPGe-detector with energy resolution of 1.0 keV for α-rays 122 keV 57Co and planar 250 mm3 HPGe-detector with energy resolution of 0.5 keV for γ -rays 53 keV 133Ba. For accumulation and analysis of the experimental information the analog electronics produced companies ORTEC, CANBERRA, Dzhelepov Laboratory of Nuclear Problem of JINR, units of the digital electronics of standard KAMAK, personal computers were used. The accumulation of information on the coincidence spectra was provided by record of each event (E1, E2, t)-coincidence (in list mode) and single spectra E1 and E2 that gave the broad possibilities for analysis result after completion experiment by means of the multiple sorting of information on spectra of the coincidences with installation the energy and time windows. In the report, a description of programs of the management and control of the on-off-line experiment designed at the begin 90-s being performed in Dubna by the YASNAPP-2 program [1-3] on the experimental complex for study nuclei far from the drip-line β-stability is given. The publication of the description of controlling programs is retard from publication of descriptions of the measuring equipment and result of the physical studies [4-6] due to in particular with creation in Institute of Nuclear Physics in Tashkent of the experimental complex γ-γ -coincidences, which can be used to accumulate the unpublished material by authors. The programs are formed in the Turbo-Pascal language with reference to the KAMAK-standard digital equipment and spectrometric equipment in standard NIM. It is properly to classify beforehand the programs in amount of 50 items: Program of the accumulation coincidence spectra of the type A-A-T with using the digital windows and ANC for 4096 or 8192 channels (off-5). Program of the accumulation spectra coincidences of the type A-A-T in mode (in list mode), i.e. formation of 3-dimensional matrixes of the coincidences. (conexe, co-on-wd, on-separ, online3, on-co-pi, recoilt, coin-buf, coin-tim, off-stab) . Program for the diagnostics of the equipment. Program of the long-term storage of single spectra with ensuring the stabilizations on the reference peaks in spectra (07-11-tm, 07-11-bf, 11-07-tm, 11-07-bf) . Program for the sorting of the coincidence spectra (p132sort, p231sort, s123sort, sum-a-g, sum-g-a, sum-g-g). Tools software (kl19-n16, 8k-to-4k, bin-dat, sum-4k, sum-8k, sub-4k, sub-8k, compr-4k, compr-8k, multi-4k, multi-8k). Program of the preliminary and final visualization of the measured results (pict-vec, surfsort, pol-3, z-pol-c). Program of the transformations of the accumulated information in type suitable for the following analysis and quantitative processing. The descriptions of the programs, block diagrams, necessary explanations upon their using are presented. In application, in view of significant volume, listings of some programs are given only. The equipment, program of management and control of experiment are used for study of the structure of the exited states of nuclei at decay of 213Bi, 209Tl [4], 221Rn [5]. The methods to determination of the absolute activity of the radioactive sources, absolute efficiency of detectors of γ-radiations and intensities weak cross-over γ-transitions [6]. (author)
