“…In particular, atomic molybdenum has attracted significant interest from the radioactive ion beams (RIB's) community due to its use in nuclear medicine. Thus, the Molybdenum production with LASer techniques (MOLAS) project at the Selective Production of Exotic Species (SPES) ISOL facility in Legnaro National Laboratories (LNL) of INFN [13], focuses on the production of the 99mTc, which is a well-known medical radioisotope, by the combined use of a cyclotron proton beam and of selectively extracting laser beams.…”

We report on measurements of resonant three-step, two-colour ionization of atomic molybdenum, using a hollow cathode lamp (HCL) with optogalvanic detection. Wavelength scans were made for two specific transitions involved in the ionization pathways under investigation, namely 4d5(6S)5s 7S3 - 4d5(6S)5p 7P4 and 4d5(6S)5p 7P4 - 4d5(6S)6d 7D5.So-called ‘slow’ and ‘fast’ optogalvanic signals were observed for each pathway. Results confirm the HCL as a cost effective spectroscopic investigation tool. In particular its use in the optogalvanic mode of operation allows one to precisely, easily and reliably tune the wavelength of one or more lasers to resonances of interest for experiments in the general domain of atomic vapour laser isotope selection (AVLIS). The measurements are closely related to the Selective Production of Exotic Species (SPES) project at the ISOL facility and were performed in the recently established laser laboratory in Legnaro National Laboratories of INFN.

“…However, this experimental set-up is not suitable for the radioactive beams of SPES [2], because of its low absolute efficiency, typically less than 1% for the ER detection. This low efficiency is due to (i) the geometrical structure of the apparatus whose effective solid angle is very small (around 0.04 msr), and (ii) to the low counting rate tolerated by the ionization chamber.…”

A new fast ionization chamber has been designed and built at the National Laboratories of Legnaro (LNL) to ensure a high counting rate particle identification for fusion studies involving exotic beams up to 10 5 pps. To reduce the response time of the ionization chamber, a design using a series of tilted electrodes has been adopted. The readout of the fast IC was optimized and extensive tests using stable heavy-ion beams demonstrated its ability to operate at high counting rates. This feature and the much larger solid angle coverage will allow to detect fusion-evaporation residues with very high efficiency.
