Title
(EN) SOUND SUPPRESSION DEVICE FOR GAS CAPTURE SYSTEM OF CYCLOTRON PRODUCT
(FR) DISPOSITIF DE SUPPRESSION DE SON POUR SYSTÈME DE CAPTURE DE GAZ DE PRODUIT CYCLOTRON
Abstract
(EN)
A cyclotron sound suppression device for reducing the decibel level of the supersonic exhaust gases. A cyclotron unit for preparing a radioisotope includes a storage tank for storing a radioactive gas resulting from preparation of the radioisotope, a compressor connected with the storage tank(s); an exhaust valve in connected with the storage tank(s); and a sound suppression device in connected with the exhaust valve. The sound suppression device can be configured as a supersonic muffler and attached to the outlet valve to diffuse the exhaust gases, thereby reducing risk of hearing damage.

L'invention concerne un dispositif de suppression de son cyclotron destiné à réduire le niveau de décibels des gaz d'échappement supersoniques. Une unité cyclotron pour préparer un radio-isotope comprend un réservoir de stockage pour stocker un gaz radioactif obtenu par la préparation du radio-isotope, un compresseur relié au(x) réservoir(s) de stockage ; une soupape d'échappement en communication avec le(s) réservoir(s) de stockage ; et un dispositif de suppression de son en communication avec la soupape d'échappement. Le dispositif de suppression de son peut être conçu sous la forme d'un silencieux supersonique et fixé à la soupape de sortie pour diffuser les gaz d'échappement, réduisant ainsi le risque de lésion auditive.
