“…The black tracks are easy to recognise visually since they are heavily ionising, they have short path lengths and stop within two lead plates. The separation between mip and grey tracks is based on the pulse height volume (PHV) [20,21] which is defined as the sum of the number of pixels associated with each track in all sixteen layers of images [22,23]. PHV indicates the track width and is therefore a measure of the grain density of a track that reflects the energy deposition of a particle in the emulsion film.…”

The OPERA experiment was designed to search for ν μ → ν τ oscillations in appearance mode through the direct observation of tau neutrinos in the CNGS neutrino beam. In this paper, we report a study of the multiplicity of charged particles produced in charged-current neutrino interactions in lead. We present charged hadron average multiplicities, their dispersion and investigate the KNO scaling in different kinematical regions. The results are presented in detail in the form of tables that can be used in the validation of Monte Carlo generators of neutrino-lead interactions.

“…In Ref. [18] we showed that charges of ion tracks can be identified up to Z = 6 with the refreshing method. Sheets-B and D were refreshed for three days under the temperatures of 40 • C and 38 • C respectively and the relative humidity of 98%.…”

We have studied charged nuclear fragments produced by 200 -400 MeV/nucleon carbon ions, interacting with water and polycarbonate, using a newly developed emulsion detector. Total and partial charge-changing cross sections for the production of B, Be, and Li fragments were measured and compared with both previously published measurements, and model predictions. This study is of importance for validating and improving carbon ion therapy treatment planning systems, and for estimating the radiological risks for personnel on space missions, since carbon is a significant component of the Galactic Cosmic Rays.

“…We conducted an experiment to study charge identification by refreshing method using HIMAC synchrotron and demonstrated that the charge of He, Li, Be, B and C, whose energies were around 290 MeV/u, were well discriminated [11]. Also this method was studied by using an emulsion scanning system developed in Italy [12].…”

The R&D project to study nuclear fragmentation using emulsion in attempt to improve the accuracy of dose calculation in carbon ion radiotherapy has been carried out at NIRS-HIMAC since 2003. Based on the developed techniques, we are accumulating experimental data of fragmentation reactions for various beams and target Preprint submitted to Elsevier Science 11 December 2008combinations. In this programme we are also developing the practical application of hybrid apparatus of emulsion and CR-39, and performing basic study of gold deposition development in order to improve measurement of ionization.
