Position- and time-sensitive coincident detection of fragments from the dissociative recombination of O2+ using a single hexanode delay-line detector

This contribution describes the use of the RoentDek hexanode delay line detector to detect fragments from the dissociative recombination of O2+ in an experiment at the ion storage ring CRYRING, Manne Siegbahn Laboratory, Stockholm.

Description
Summary:This contribution describes the use of the RoentDek hexanode delay line detector to detect fragments from the dissociative recombination of O2+ in an experiment at the ion storage ring CRYRING, Manne Siegbahn Laboratory, Stockholm. In this experiment, the fragments have a maximum time- and position-separation of 20 ns and 40 mm, respectively. The position resolution obtained was 0.16 mm (FWHM) on the 67 mm diameter detector. The time resolution obtained from the time-of-arrival difference between the product fragments was about 1 ns. The detector system handles event rates as large as 30 kHz. Techniques for the calibration of the absolute position of particles on the detector are discussed.
