1. Silicon Module Tests The modules are tested in the production labs. HIP is is participating in the rod quality tests at CERN. The plan of HIP CMS is to build a minitracker facility in Helsinki (Kumpula detector lab) to study system aspects and tracking with cosmic rays and a source, when production of rods is advanced enough. As a first step a single module test setup has been built by HIP CMS at CERN. It is being used in collaboration with the CERN TOB group. BUT: The minitracker project of HIP is on hold due to lack of funds.

2. R&D on Radiation Hard Detectors Novel types of silicon structures being processed at HUT Microelectronics Center (1) Electric measurements in the Kumpula Clean Room Irradiations at Jyväskylä Accelerator Center (2001 – 2002) (2) Measurements at the H2 beam at CERN with the HIP SiBT 1 2

3. Detector tests The full size Cz processed detectors have been successfully tested in summer 2002 at the H2 test beam at CERN with the HIP SiBT. They show comparable performance to the conventional FZ detectors The irradiated Cz detectors have been measured again at the H2 beam with SiBT in 2003.

4. R&D collaboration partners Good collaboration with national and international partners: Microelectronics Centre, Helsinki University of Technology Laboratory of Machine Design, Helsinki University of Technology Accelerator Laboratory, University of Jyvaskylä CERN RD50 and RDF39 collaborating institutes –Brookhaven National Laboratory (USA) –University of Hamburg (Germany) –Ioffe Physico-Technical Institute (Russia )

5. SAB 3.6.2002Eija Tuominen5 RPC Link Activities Link Board for the RPC muon trigger and data transmission has been designed as a Helsinki-Warsaw project. The prototype is ready and tested in a beam at CERN (1). Design for Board Integration to CMS is being completed (2). Link Board production (2100 boards) will take place in 2004 in Finland under supervision of the University of Lappeenranta. 1 2
