“…High Z-value and energetic (HZE) particle in PADC detectors response has been studied by Palfalvi et al [2] considering their exposure to mono energetic particles from a low intensity beam. Studies were made to interpret complex nuclear tracks [3,4]. However, development on the etched track-particle correspondence is still active, suggested employing successive etching time to improve the technique by demonstrating the necessity to include LET-value (Linear Energy Transfer) measurement to determine PADC-response.…”

Passive nuclear track methodology (NTM) is applied to study charged particles products of the reaction 7Li+Pb at ~ 31 MeV. It is a contribution to the 8pLP Project (LNL-INFN-Italy) in where we show an alternative approach to register charged particle from reaction fragments by PADC detection. The main advantage is that the passive system integrates data over the whole experiment and has its importance for low rate reaction processes. Reaction products as well as scattered beam particles are determined from track shape analysis. Some limitations are inherent to NTM since a priori knowledge is required to correlate track size distribution given by each type of particle emerging from the target. Results show that the passive technique gives useful information when applied in reaction data interpretation for a relatively large range of particle types.

CN-85 detector which covered with boric acid H 3 Bo 3 pellete has been irradiated by thermal neutrons from ( 241 Am-9 Be) source with activity 12 Ci and neutron flux 10 5 n. cm −2 . s −1 . The irradiation times-T D for detector were 4 h, 8 h, 16 h and 24 h. The track detector has been etched with sodium hydroxide. After chemical etching of the irradiated CN-85 detector, the images have been taken from a digital camera connected to the optical microscope. Image processing for the output images has been performed using MATALB program, and these images were analyzed and we had found the following relations: a) The relation between summation of opened track or surface density for tracks (intensi- 0.4225, 0.845, 1.2675 and 1.69 µm). The study indicates the possibility of using the analysis of image processing to CN-85 detector for classification of α-particle emitters through limitation of radius of track-R T , in addition to the contribution of these techniques in preparation of nano-filters and nono-membrane in nanotechnology fields. ty-IT) varies with radius of opening (track radius-R T ). b) The relation between the tracks number-N T varies with the tracks diameter-D T (in micrometer) and tracks area-A T . That analysis of image processing was obtained, and the track intensity-I T was decreased with increase of track radius-R T at all of the irradiation time-T D . And the track intensity-I T was increased with increasing irradiation time-T D (h) for different track radius-R T (

“…To improve the EURISOL detection capability, a complementary system is proposed, since a large set of experimental results have been obtained with passive polyallyldiglicolcarbonate, PADC for short, or (C 12 H 18 O 7 ) detectors in nuclear interaction studies by Barbui et al [5]. The technique demonstrated their importance in several fields, for example, in galactic cosmic ray (GCR) and studies on the ISS, Pálfalvi et al [6].…”

A higher yield of rare isotope production methods, for example, isotope separation on-line (ISOL), is expected to be developed for the EURISOL facility. In this paper as a part of the ongoing project, high power-target assembly and passive detector inclusion are given. Theoretical calculations of several configurations were done using Monte Carlo code FLUKA aimed to produce 1015 fiss/s on LEU-Cx target. The proposed radioactive ion beam (RIB) production relies on a high-power (4 MW) multibody target; a complete target design is given. Additionally we explore the possibility to employ PADC passive detector as a complementary system for RIB characterization, since these already demonstrated their importance in nuclear interactions phenomenology. In fact, information and recording rare and complex reaction product or short-lived isotope detection is obtained in an integral form through latent track formation. Some technical details on track formation and PADC detector etching conditions complete this study.
