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.
