EPTAB4 Rental: Application Oriented Sets for LHC Detector Electronics

Explore the possibility of creating application-oriented sets for LHC detector electronics through the EPTAB4 Rental program. This compromise scheme offers a constant rental cost based on initial cost, estimated usage, and maintenance charges.

  1. EPTAB4

  2. News • BAAN400 – move underway • June? • Destocking continuing • The pool has many low-rental items with high repair costs • LeCroy HV mainframe • Rental 17 CHF/month • Repair 1,050 CHF • LeCroy NIM dual amplifier • Rental 6 CHF/month • Repair 415 CHF • Evaluation of NIM in VME form-factor starting • Latest introductions EPTAB4

  3. Rental Fee Profile EPTAB4

  4. Pool Users May 2003 Total LHC Experiments 41.7% EPTAB4

  5. Financial Predictions Best case?Assumes that CMS will keep equipment in place at “overhead” rate of 18%, no fixed target and other users continuing at 2004 levels Guess!Assumes that CMS will resume at 2004 levels, no fixed target and other users continuing at 2004 levels EPTAB4

  6. Future Of Pool • The Pool must continue • W-D.S., V.V., R.C. • If dismantled, unlikely to be ever restarted • Technical quality control – should this be compromised? • 2005 • Only CMS has requested test beam after 2005…? • Fixed target programme? • Find strategy to get past 2005 • Extra customers • Occupy staff • Use income in 2003/4 for survival and to focus the pool • Bank some revenue to meet incompressibles in 2005 • To preserve infrastructure • Set up coherent product lines • Application orientated sets • Renew the pool stock • Benefit from 2 year guarantee • Input required on • Likely use of the Pool in 2005 and after • Contact with resource coordinators, technical coordination… • Other “pools” at CERN EPTAB4

  7. Rental • Existing scheme • Heavy, unrealistic, difficult (~impossible) to implement • Not transparent • Possibilities • “Commercial” scheme • Life-time amortisation • But we don’t sell off equipment at end of life (as does a car rental) • We do not aim to be “commercial”, but to provide a service • Too much selling off would put us in competition with ourselves in a small market • Transparent • No rental • Funding by levy on experiments & support groups pro rata to needs • Moves the problem • Need to put responsibility for equipment at the appropriate level to ensure its proper treatment & return to pool • Not transparent EPTAB4

  8. Rental Conditions – Current Model Lifetime 5 years EPTAB4

  9. Lifetime Amortisation Lifetime 5 years EPTAB4

  10. Compromise Rental Scheme • Soften the strict business model • Problems with lifetime amortisation • Constant rental fee • Set by pool operations based on • Initial cost • Estimated useful lifetime • Likely maintenance charges • Likely usage • End of life change in fee linked to level of technical support • Based on statistics from real use • Transparency • Justify to EPTAB/EAB… EPTAB4

  11. Compromise – Constant Rental Costs exceed revenue - action! EPTAB4

  12. Application Orientated Sets • Take a functional view of detector readout electronics • Examine which functional blocks should/could be included in the Pool • Survey the functional requirements and needs for LHC • Detector functions and technologies • Electronics • Requirements for R&D and commissioning • Practical examples of solutions adopted • Which items could not be found from the Pool? EPTAB4

  13. Detector Computer interface Pulse Shaper Computer ADC Memory Amplifier TDC Discr. High- Bandwidth (> a few 100MHz) STANDARD MODULES AND CUSTOM MODULES Trigger Logic A functional view of the readout electronics Typical Read-Out CUSTOM MODULES • Creation of a database of the • existing circuits: • Circuit specifications • Availability • Contact person • etc. EPTAB4 Specificity increases, EPOOL role decreases
