Production of neutron deficient rare isotope beams at IGISOL; on-line and off-line studies

2004

This article reports on recent on-line yield measurements employing the light-ion and heavy-ion reaction-based ion guide systems and new results on a-recoil ion transport properties in ion guides with and without electric fields. In addition, the presently used ion guide designs for fusion evaporation reactions are introduced. The present study investigated different schemes for ion extraction from the gas cell. The addition of an extra ring electrode between the traditional skimmer electrode and the exit hole led to transmission independent of the primary beam intensity as opposed to strong intensity dependence observed earlier with the plain skimmer only. Furthermore, the mass resolving p…

Neuronavigation-guided biopsy for differential diagnosis of pseudotumoral demyelinating brain lesions

2014

Abstract Marburg's disease (MD) is an extremely rare and aggressive form of multiple sclerosis (MS). In some cases, MD presents with tumefactive demyelinating lesions with a “tumor-like” appearance in MRI images, for which it may be difficult to achieve a form of differential diagnosis between definitive tumors or abscesses. Here we report a case of MD histopathologically confirmed after neuronavigationguided biopsy. Postoperative course was uneventful and following discharge, the patient attended outpatient follow-up appointments and received i.v. cyclophopsphamide, achieving progressive clinical remission. A nine-month follow-up brain MRI scan with gadolinium showed no signs of progressin…

The development and status of the IGISOL technique

1997

Abstract The development of the IGISOL technique since its earliest beginnings at the University of Jyvaskyla in the early '80s is reviewed. The processes involved in ion survival in the ion guide are discussed. The design and performance of ion guides for different types of reactions is summarised. The mass-separated beam quality for different skimmer systems is compared.
