1. A Cost Model for KM3NeT Uli Katz Physics Institute University Erlangen-Nuremberg KM3NeT WP2 Meeting Oct. 24, 2006, Marseille Based on a presentation by Alexander Kappes at the PCC meeting in Rome, Sept. 28, 2006

2. 24. Oct. 2006 KM3NeT WP2 Meeting, Marseille2 Uli Katz University Erlangen General Considerations Aim of Design Study: Develop detector design optimized for physics sensitivity Figure of merit: Physics sensitivity relative to costs  requires cost model comprising (no personnel):  Detector  Infrastructure  Sea operations  Operation of detector  Maintenance Question to cost model: What will be the costs for a specific detector design at a specific site assuming a certain lifetime?  needed to compare different KM3NeT options (together with physics-sensitivity information from WP2) Responsibility: WP1 (Management)

3. 24. Oct. 2006 KM3NeT WP2 Meeting, Marseille3 Uli Katz University Erlangen Specific Requirements for Cost Model High flexibility: allow for easy combination of components (units) to different detector setups at different sites Reliable cost estimates to allow comparison of different KM3NeT options:  detailed cost breakdown structure  WPs have to provide accurate price tags for each component, operation etc. Interface to simulation software: access to cost information through simulation software

4. 24. Oct. 2006 KM3NeT WP2 Meeting, Marseille4 Uli Katz University Erlangen Vari-Calc Difficult search - only one suitable product found: Vari-Calc from Kutzner Software (originally developed in EU FP3 project) Costs: about 10 kEuro (including installation and adaptation to our specific needs) Server-Client architecture with SQL-Server Direct access to database possible … can be interfaced by other programs Demo version available (buggy, improved version promised)

5. 24. Oct. 2006 KM3NeT WP2 Meeting, Marseille5 Uli Katz University Erlangen Hierarchical multi-level structure of units Principle structure of a unit: Further sub-units for e.g. “legs” down to smallest unit. “Table” is one sub-unit for unit “office” etc. Table total costs = add. costs + sub-units 1 4 table legtabletop screws assembly costs number of sub-units sub-units unit

6. 24. Oct. 2006 KM3NeT WP2 Meeting, Marseille6 Uli Katz University Erlangen Cost Model Structure for KM3NeT (Simplified) “KM3NeT” highest level (includes all costs) Contract: First draft of cost model until Sept. ‘06 storey type I vertical structure type I detector type I detector type II KM3NeT type IKM3NeT type II site Isite II KM3NeT type III (includes infrastructure etc.) vertical structure type II
