    Abstract The performances of white light cooling are shortly reviewed and discussed. The velocity distributions modified by the cooling laser are calculated under different boundary conditions and a new experimental approach, which permits to obtain a sharp edge laser bandwidth, is taken into consideration. Finally, the preliminary experimental results on a sodium beam cooled by a lamp laser are reported.

    Abstract: A detailed theoretical and experimental description of a sodium MOT as a function of the pumping and repumping laser frequencies and intensities is given. The effective trapping schemes and the collection efficiency have been experimentally measured and calculated by solving an original 3D model. This model considers the whole bunch of the 32 ground and excited (P1/2 + P3/2) Zeeman sublevels, the actual trap geometry, the magnetic field intensity and direction, the light polarization, and evaluates both the velocity capture range and the number of trapped particles N. Synergetic and competition mechanisms due to the trapping and repumping lasers have been predicted and experimentally observed. The model simulation has been compared with the results reported in the literature and with those obtained by us and a quite good agreement has been found. The model can be easily adapted to the other sodium isotopes as well as to all the other alkalis.

    Notes:
    Abstract: The light induced atomic desorption effect, known as LIAD, is observed whenever Pyrex cells, coated with siloxane films and containing alkali atoms, are illuminated. LIAD is a non-thermal phenomenon and it can be observed even with very weak light intensities. We show that the simultaneous contribution to the photo-emission of atoms adsorbed both at the film surface and within the film must be taken into account in order to fit the experimental data. We demonstrate that both the desorption efficiency and the diffusion coefficient of the alkali atoms embedded in the dielectric film depend on the desorbing light intensity. These features characterize a new class of photo-induced phenomena whose analysis gives new insights in the comprehension of the atom-surface interaction and of the atom-bulk diffusion and opens interesting perspectives for applications.

    Abstract We have developed broad-band laser sources which show a sharp edge in their spectra and are particularly suitable for ``white-laser'' cooling of ions in storage rings. They allow for a very large velocity capture range by maintaining the same cooling rate allowed by the single mode lasers. A large fraction of the circulating ions are expected to be cooled both in coasting and bunched beams. The device, which does not use an active medium, can easily operate at any frequency from UV to IR spectral region.

    Abstract “White-light” cooling of an ion beam confined in a storage ring has been demonstrated at Test Storage Ring in Heidelberg. Measurements aimed at comparing “white-light” with single-mode laser cooling show that “white-light” cooling gives lower temperatures at higher ion densities both in a coasting and in a bunched beam.

    Abstract A Monte Carlo code combined with a particle tracking program has been used to study a stroboscopic laser diagnostic system that is able to detect a string-like ordered ion beam. Different ion species have been studied to evaluate the diagnostics capability.

    Notes:
    Abstract A novel diagnostic method to detect ordering within one-dimensional ion beams in a storage ring is presented. The ions are simultaneously excited by a ultrashort pulsed laser (≃ 1 ps) at two different locations along the beam and fluorescence is detected by a group of four photomultipliers. Correlation in fluorescence signals is a firm indication that the ion beam has an ordered structure.

    Notes:
    Abstract We propose the use of a “white laser” for laser cooling of ions in a storage ring. The use of a broad-band laser provides a radiation pressure force with wide velocity capture range and high magnitude, which is promising to improve the performance of both longitudinal and indirect transverse cooling. This wide-range force could also be suitable for direct transverse cooling of low-density beams.

    Notes:
    Abstract A frequency comb in the UV region with a bandwidth greater than 100 MHz is generated by successive frequency shifts of a single mode laser by an acousto-optic modulator coupled to a passive ring cavity. The obtained spectrum is particularly suitable for laser cooling when a large velocity capture range is required as in the case, for example, of ions confined in a storage ring.

    Description / Table of Contents:
    Sommario Gli Autori presentano una serie di 36 meningiomi spinali trattati chirurgicamente. Essi sottolineano come, troppo spesso, i sintomi di un meningioma spinale siano male interpretati e riferiti ad altre e più comuni malattie della colonna come la spondiloartrosi o l'ernia del disco. La mielografia e la tomografia computerizzata dovrebbero essere utilizzate più frequentemente per ridurre i tempi di diagnosi di un meningioma spinale. L'asportazione dell'impianto durale del tumore non è sempre indispensabile per prevenire possibili recidive.
    Notes:
    Abstract We present a series of 36 surgically treated spinal meningiomas, emphasising that the complaints of a patient with spinal meningioma are too often misinterpreted and ascribed to other, more common, affections of the spine such as spondyloarthrosis or disc prolapse. CT scanning and myelography should be used more routinely, in order to reduce the delay in diagnosing a spinal meningioma. Excision of the dural attachment is not always essential to avoid recurrences.
