Підтримка: The Institut Laue-Langevin is gratefully acknowledged for providing both neutrons and prompt technical assistance. We thank all the members of the BRISP CRG for their contributions to the development of BRISP. In particular, we wish to thank F. Barocchi for promoting the project in Italy, T. Gahl for the construction of the large bidimensional detector, F. Formisano and L. Sani for the development of the data formatting software, A. Cunsolo for his help during the beamline installation, A. De Francesco and A. Laloni for their reliable management of the instrument since the first months of operation, and E. Guarini for her technical support in Italy. A warm and grateful acknowledgment is finally addressed to the technicians of the Physics Department of the University of Perugia (E. Babucci, D. Aisa, S. Aisa and A. Piluso) for their invaluable support to the spectrometer construction, and to the technicians of the University of Marburg (W. Kroeschel and M. Freundorfer) for their efforts concerning the completion of the position sensitive detector.

BRISP, a new small-angle time-of-flight neutron spectrometer to study collective dynamics in disordered matter

Анотація:

An outline is given of the new neutron Brillouin Spectrometer BRISP which was installed during the last years and recently became fully operational at the Institute Laue-Langevin in Grenoble (France). The main technical features are described and some of the first experimental results are presented, demonstrating the present capabilities of this new-type inelastic small-angle spectrometer. Future upgrades are foreseen and expected to further improve the instrument performances.

Подано короткий опис нового нейтронного брiлюенiвського спектрометра BRISP, що iнсталювався протягом останнiх рокiв та недавно почав дiяти в Iнститутi Лауе-Ланжевена у Ґреноблi (Францiя). Описано основнi технiчнi особливостi та представлено деякi першi експериментальнi результати, що демонструють наявнi можливостi цього малокутового непружнього спектрометра нового типу. В майбутньому передбачаються та очiкуються вдосконалення для майбутнього покращення роботи iнструмента.
