I think you did not receive this message, so now I send to you a more detailed message asking for some information. I am one of the members of the group at the Universitat Politecnica de Catalunya (Spain) working on the desing of a neutron detector for DESPEC. This detector surrounds the Advanced Implantation detector Array (AIDA) which your group have developed. Daniel Cano (from CIEMAT - Spain) gave us your Technical Specification, version 1, and we have some questions about it. Your answer is very important for us to be able to continue our work. I send you a document whith a basic description of the preliminary version of our detector. Our questions are the following: 1- Which are the dimensions of the silicon detector array which will be inside the neutron detector?. We need the overall dimensions including the supporting structures, the vacuum chamber, electronics, etc. 2- Which part of the silicon detector array must be inside the neutron detector? 3- The structure of the target and the distance from one DSSSD package to the next one. 4- How many DSSSD packages will be?. 5- Why there are two types of DSSSD packages.? 6- Which is the position of the DSSSD packages: vertical or horizontal in the case of 24cmx8cm type? 7- Could you please send us a drawing of the detector structure (Autocad file or another format that includes dimensions) ? Thank you very much for your help.
