The response of silicon–silicon–CsI(Tl) and siliconCsI(Tl) telescopes to fragments produced in nuclear interactions has been studied. The telescopes were developed within the FAZIA collaboration. The
capabilities of two methods are compared :

  • (a) the standard DeltaE-E technique
  • (b) the digital Pulse Shape Analysis technique (for identification of nuclear fragments stopped in a single Si-layer).

In a test setup, nuclear fragments covering a large range in nuclear charge, mass and energy were detected. They were produced in nuclear reactions induced by a 35 AMeV beam of 129Xe impinging on various targets.

It was found that the DeltaE-E correlations allow the identification of all isotopes up to Z - 25. With the digital Pulse Shape Analysis it is possible to fully distinguish the charge of stopped nuclei up to the maximum available Z (slightly over that of the beam, Z around 54).
