We are fully aware of the challenging characteristic of the silicon target detector proposed. This detector tries to satisfy in the optimal way the requirements for the charm physics program.
Aware of the open questions regarding the effective performance, we already started the preparations to perform full scale device tests within the current year.
These tests together with the constant contacts with the RD20 group will allow us to judge rather quickly the feasibility of the current design, to collect new ideas and to obtain prospects for improvements or alternatives.
