Abstract

An internal irradiation system has been developed at the injector cyclotron of COSY which allows the use of the conventional stacked-foil technique for excitation function measurement. The beam quality tests consisted of: (i) determination of the beam profile via activity measurement; and (ii) measurement of the proton flux over a wide energy range using monitor reactions of different thresholds. An example of the application of this facility is mentioned.

    Protons and alpha particles can be accelerated up to 70 MeV whereas deuteron beams can be accelerated only up to 34 MeV. The irradiation process was carried out at the ARRONAX cyclotron in a typical configuration for stacked-foil experiments (Blessing et al., 1995). In these experiments, monitor foils were used to determine the beam flux and degrader foils to adapt the energy of the beam impinging consecutive targets.

    The experimental results have been compared with the available literature data of the EXFOR [12], theoretical data of the TALYS-1.95 code [13], and evaluated nuclear data of the ENDF/B-VIII.0, JENDL-4.0/HE and PADF-2007 libraries. The excitation functions of the proton induced reactions on the natural iron were measured as a function of the proton energy in the range of 85–100 MeV by using a well-known stacked-foil activation technique followed by high-resolution γ-ray spectrometry [14,15]. The high-purity (99.98%) iron foils (25 μm thickness) were used as the target for the irradiation.

    It was slightly reshaped after entering the extended beam line (Fig. 2) by setting the aperture of the collimator. To determine the beam profile at the target positions, a Cu foil was irradiated for 30 min at a low current of 1 µA and the contour of the radioactive spot was determined (cf. Blessing et al., 1995) by instant imaging using a Packard Instant Imager. The results for an 8 mm aperture collimator are shown in Fig. 6.

    Only minor spread of the beam was observed. The same was true for the deuteron irradiations at the JULIC cyclotron as earlier discussed in detail (Blessing et al., 1995). The particle energy degradation was calculated beforehand with the Excel-routine STACK which is based on arithmetical calculations (Livingston and Bethe, 1937) with a numerical adjustment (Williamson et al., 1966).
