  3. Application dependent coherent sets • Working towards completing a set of modules in VME form-factor • Work on selector guides continuing • http://ess.web.cern.ch/ESS/EquipmentSelectorGuide/ • Evaluating • CAEN V895 VME 16 Channel LeadingEdge Discriminator • 16 input channels • ECL outputs with fan-out of two • Selectable Updating/Non Updating mode • Programmable output width • VETO and TEST inputs • OR, CURRENT SUM and MAJORITY outputs EPTAB5

  4. 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. EPTAB5 Specificity increases, EPOOL role decreases

  5. Discussions with ISOLDE • Exploratory talks • Equipment from Pool • Waiting for input from ISOLDE • DAQ • Asking for application support EPTAB5

  6. Database management • Fully functional test version of BAAN400 made available by AS Division • Discussion on web interface and connection to the Material Request procedure underway EPTAB5

  7. De-stocking • List of non-functional equipment for disposal ready for publication • FASTBUS equipment • LEP crates, modules • Do we need to advertise before scrapping? • Any possible use to HEP? EPTAB5

  8. C-RAMS testing • CAEN V550, V551 • “Readout for Analogue Multiplexed Signals” • 2-channel 10 bit ADCs with sequencer • Tests being in-sourced • Expensive and light-weight • Pool status: • Rental: 31 CHF/month • Total: 102 • Used: 76 EPTAB5

  9. New additions • LeCroy LT354 “Waverunner-2” scopes • 4 Channels • 500 MHz Bandwidth • 1 GS/s Single-Shot Sampling Rate on all channels • 50 GS/s Repetitive Sample Rate • Better than 10 ppm Timebase Accuracy with 5 ps resolution • Qty: 5 • Pool status: • Rental: 176 CHF/month • Total: 15 • Used: 11 EPTAB5

  10. Requests • CMS • SBS618: PCI to VME optical link • Only 4 in prospect for the Pool • Not ordered EPTAB5

  11. Financial conditions • Presented to EAB on 23 May • Memo to Cashmore in preparation • Simplified conditions for • Rental • Compensation • Resales EPTAB5

  12. Rental scheme – compromise proposal • Rental fee based on • Average purchase price (VAM) • Estimated useful lifetime • Likely maintenance charges (guarantee period, repair contract) • Likely usage • Costs monitored regularly • Verification after rental • Repairs • When costs exceed revenue - action! • Full or partial renewal of stock • New equipment, new guarantee • Equivalent function with lower maintenance costs • Modification of level of support • Increase in rental fee • Declassification • Rental fee may change – (annual review?) • Excessive costs (increase) • New purchases (VAM) (increase or decrease) EPTAB5

  13. Rental scheme – compromise proposal • Advantages • Simplifies existing procedures • Based on support and utility to users • Allows the revenue to cover real costs • Automatic regulation of overall rental • Implies close monitoring of revenue and costs • Transparency • Via EPTAB/EAB EPTAB5

  14. 2 year guarantee period Compensation - loss or major damage • Present system leads to anomalous (high) payments for old equipment • Age calculated from 1 Jan 1990… • Proposal • Annual 10% reduction of purchase price to a minimum of 10% after 10 years • Full purchase price for 1st year EPTAB5

  15. Re-sales of surplus equipment • Present system applies the compensation value • Propose • Fully tested in working condition • Compensation value • Untested in uncertain condition • Case-by-case • Market value EPTAB5
