11. Status on deliverables " A FDR document is in preparation which has been a reference document in some FDR of SCT subsystems " Deliverables have been specified and costs are being updated " First final ELMB units are available

12. Near future activities " This autumn work on combining power supplies, cooling and environment under PVSS main task. Work will be done both in the system test lab and the cooling lab. " Early 2002, get a full DCS system going in Oxford Team: S. Basiladze, R. Brenner, R. Waistie, P-O. Wallin...

13. Near future activities (cont.) " Need to proceed with FDR/PRR in order to buy a large fraction of the final DCS components.
