2. True coincidence summing corrections

Useful resources on the Web

Dr. Gordon Gilmore (who was an invited speaker at the first GammaSem seminar) has for years maintained web sites with useful information on gamma spectrometry, see e.g.:

http://www.gammaspectrometry.co.uk/

Using good quality nuclear data is essential for gamma spectrometry. Recommended data can be obtained from

http://www.nucleide.org/DDEP_WG/DDEPdata.htm

The following web site offers nuclear data that can be extracted from a data base, in accordance with selection rules set by the user (e.g. energy and intensity threshold).

hThe following information on four useful utilities was contributed by Mark Dowdall after the first GammaSem seminar:

SPECON 2000 Spectrum conversion utility

Specon is a converting utility between various spectrum files having various binary formats (SPEctrum CONverter). Many formats of the spectrum are produced by various MCAs and analysis codes such as RUMP and SENRAS. Some of them have not only count data of channels but also experimental conditions or conversion factors which are used for converting channel to some physical values (energy, time and so on). Specon can automatically identify 14 binary formats and three ascii formats. They can be completely converted to each other including experimental information if possible. Viewer has several functions of a simple MCA such as ROI, zoom, background subtraction and comparison of two spectra. Specon can convert the channel from as energy to as time, and vise versa during conversion.

CAMBIO

CAMBIO is a powerful conversion utility and spectrum manipulator primarily aimed at the emergency response community. Cambio is an application intended to automatically read and display any spectrum file of any format in the world that the nuclear emergency response community might encounter - including unknown types. More information may be found at:

The software may be obtained by contacting: George Lasche at gplasch at sandia.gov

ETNA (Efficiency Transfer for Nuclide Activity)

ETNA is a user friendly application for conducting efficiency transfer operations and some coincidence summation correction.

Full details can be found in: Efficiency transfer and coincidence summing corrections for g-ray spectrometry Francois Piton, Marie-Christine Lepy*, Marie-Martine Be, Johann Plagnard, Applied Radiation and Isotopes 52 (2000) 791-795

The package can probably be obtained by contacting Marie-Christine Lepy at marie-christine.lepy at cea.fr

TRUECOINC

Truecoinc is a free Windows utility for calculating TCS corrections. It can be obtained by ordering a printed (comes with CD) copy of http://www-pub.iaea.org/MTCD/publications/PDF/te_1275_prn.pdf.

Or by download here: http://kisfiz.phys.klte.hu/kisfiz/sudar/truecoinc.htm
