  • Balloon dilation of benign esophageal rings or strictures : a randomized clinical trial comparing two different inflation times

    • Although balloon dilatation is the primary treatment for benign dysphagia, information about the optimal inflation time is lacking. The aim of the current pilot study was to compare 10 seconds inflation time with 2 minutes inflation time, regarding the efficacy. Twenty patients with symptomatic strictures were prospectively studied in a randomized fashion. The 10-second group required an average of 1.4 dilations per patient; the 2-minute group required an average of 1.5 dilations per patient. This pilot study indicates that 10 seconds inflation time is as effective as 2 minutes. Because the treatment is both painful and unpleasant, this is an important finding.

    • Recent progress with compact ionization chambers has opened new possibilities for isobar Refraining from the additional use of degrader foils has the benefit of high transmission to the detector Precision and accuracy have been thoroughly assessed over the last two years. Since drifts in the Recently we also explored novel techniques for additional sulfur suppression already in the ion source.

  • Measurement of the angular distribution of fission fragments using a PPAC assembly at CERN n_TOF
  • 2014
  • Ingår i: Nuclear Instruments and Methods in Physics Research Section A. - : Elsevier BV. - 0168-9002 .- 1872-9576. ; 743, s. 79-85
  • Tidskriftsartikel (refereegranskat)abstract
    • A fission reaction chamber based on Parallel Plate Avalanche Counters (PPACs) was built for measuring angular distributions of fragments emitted in neutron-induced fission of actinides at the neutron beam available at the Neutron Time-Of-Flight (n_TOF) facility at CERN. The detectors and the samples were tilted 45 degrees with respect to the neutron beam direction to cover all the possible values of the emission angle of the fission fragments. The main features of this setup are discussed and results on the fission fragment angular distribution are provided for the Th-232(n,f) reaction around the fission threshold. The results are compared with the available data in the literature, demonstrating the good capabilities of this setup.
