Time of flight with a segmented plastic finger detector at high particle rate — •Frederic Ameil1, Miroslav Danchev2, Plamen Boutachkov3, Jan Kurcewicz1, Stephane Pietri1, Damian Ralet1, Jürgen Gerl1, and Norbert Pietralla3 — 1GSI, Darmstadt, Germany — 2University, Sofia, Bulgaria — 3TU, Darmstadt, Germany
Improved primary beam intensities and implementation of fast ramping time converts directly into higher yields of exotic nuclei. Improvements to tracking detectors are necessary to allow for higher rates.
The segmented plastic finger detector was refurbished, tested and used in several beam times at the FRS and a better resolution was obtained compared to conventional scintillator detectors especially at high particle rate (> 106 Hz).
A new finger detector with higher segmentation is under development, it can allow for still higher rate and can be also used as tracking detector for the SuperFRS.
