ICARE is the charged particles detector system used for their identification and energy measurements. Built in the IReS (Strasbourg) is presently installed at HIL (Fig.1).

ICARE at HIL - project milestones

  1. April 2004 - first ideas
  2. December 2004 - official statement from IReS and HIL
  3. December 2004 - program PICS dedicated for the project started
  4. May 2005 - ICARE set-up test performed in Strasbourg
  5. July 2005 - experimental vault for ICARE adapted
  6. November 2005 - ICARE transported to Warsaw
  7. December 2005 - assembly of ICARE mechanical parts in the vault (with the help of IReS team)
  8. November 2007 - first experiments

Figure 1: Localization of the ICARE setup in the HIL experimental hall.

The ICARE system consists of the 1m diameter reaction chamber with up to 48 E-ΔE gas and semiconductor telescopes , supplied with the electronics and data acquisitions systems (see Fig.2).

Figure 2: ICARE at HIL.

The detectors can be mounted in any configuration preferred by users, using internal mounts. The self-supporting target holder allows to use up to 6 different targets. It can be remotely operated without necessity of opening the reaction chamber. The detector system layout is presented in Fig.3.

The ICARE system can be equipped with three kind of telescopes :

An example of charge and mass identification from test measurement of angular distribution of products from 14N + 12C are in Fig. 5.

On the plot: raw spectra ΔE vs E.

Experimental programme to be performed using the ICARE system:

  • Study of properties of isotopes far from stability line produced in heavy-ion reactions.
  • Studies of fusion barrier height distributions using the quasi-elastic scattering method.
  • Study of nucleus deformation using light-charged particles emission spectra.
