Proton imaging has been proposed as an alternative low-dose imaging technique for acquiring relative stopping power (RSP) maps and for patient positioning. In proton therapy and hadrontherapy, the water equivalent thickness (WET) of a material represents its radiological thickness, however, its calculation requires computationally intensive methods or approximate solutions. At IEM-CSIC, we have developed a scanner prototype for imaging with protons composed of two double-sided silicon strip detectors (DSSSD) and fast scintillators with high energy resolution, detectors that are commonly used in Experimental Nuclear Physics. Two custom-made samples of aluminum, air, and polymethyl methacrylate (PMMA) were imaged and their proton radiography images (pRads) are presented in terms of WET. Pattern reproduction, spatial resolution, and sensitivity to di↵erent materials were studied. We present pRads of our samples obtained using a rather traditional approach to compute WET values. All three materials of the studied samples, aluminum, PMMA, and air, were well distinguished; the resulting WET values were in good agreement between samples. [ABSTRACT FROM AUTHOR]

We report on the preliminary results of an experimental study of the β decay of 16N, aiming to determine the branching ratio of the βα channel with a precision of ≤ 5%. [ABSTRACT FROM AUTHOR]

The study of excited states of unbound light nuclei includes the simultaneous detection of several charge particles emitted with very low energy. This puts several constrains on the detection system to be used. For the detectors, high segmentation is needed to be able to detect several coincident particles without an exponential drop in efficiency. The high segmentation of the detectors leads to experiments with an increased amount of electronic channels. For very dedicated experiment integrated electronic chips can be prepared, but in many cases where the detector set-up are frequently being changed, one still have to rely on more traditional analogue electronic circuits. News in the field of charge particle detection will be discussed. [ABSTRACT FROM AUTHOR]

Target and ion source constitute the heart for the production of radioactive ion beams, RIBs. The goal of this work is to help in the development of reliable and efficient target and ion source systems for production of short-lived isotopes of a wide range of elements by the ISOL method. With this aim an oracle database of diffusion and desorption parameters with more than 10.000 entries has been built. The database is accessible on line and a web application has been developed allowing the retrieval of information from the database in order to assist in the configuration of the input parameters for a Monte Carlo code, RIBO, for the simulation of target-ion source systems. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
