We present a concept of using Timepix detector for real-time and simultaneous measurements of various external dosimetry and operational quantities in X-ray/gamma fields with broad range of air kerma rates ranging from natural background levels to the order of Gy·h−1, including intensive pulsed sources used in medicine. Timepix is a hybrid semiconductor detector of ionizing radiation which can visualize...
A demonstrator of the portable position sensitive neutron detecting device for neutron imaging in a mixed radiation field is presented. A detector of the device is based on multilayer perpendicularly crossed strip sensors interlaced with neutron converter. A 6LiF converter producing energetic alpha particles and tritons is used. The converter permits precise determination of a position of the neutron...
Doping of clusters by sodium atoms and subsequent photoionization (NaPI) is used as a fragmentation-free cluster ionization method. Here we investigate different clusters using NaPI and electron ionization (EI) with a reflectron time-of-flight mass spectrometer (RTOF). The mass spectra of the same clusters ionized by NaPI and EI reveal significant differences which point to Na reactivity in the clusters...
