  1. Cost estimation for production & installation of Calorimeter System V. Issakov Physics Department, Yale University, New Haven, CT 06511 11/9/2004

  2. Photon Calorimeter for KOPIO All sizes are millimeters • The requirements to the KOPIO Photon Calorimeter: • Energy resolution  3.5[%]/E. • Time resolution  100[psec]/E. • Photon detection inefficiency (due to holes-cracks)  10-4. • Granularity 1111 cm2. • Active area  5.7 5.7 m2 • Radiation length 16X0 • (18X0 including Preradiator). • Physical length  60 cm. • The Shashlyk technique with the APD photo readout satisfies the KOPIO requirements.

  3. Calorimeter System • Calorimeter System includes: • Mockup of Calorimeter System - the complete-equipped prototype of Calorimeter system (168 modules), to study the performance parameters of the Calorimeter & Preradiator/Calorimeter systems and to develop the pattern recognition algorithms. • Photon Calorimeter – the matrix of the 5252 APD-instrumented modules with a beam hole of 182 modules , Calorimeter mechanics (including two mobile halves of Calorimeter frame, Calorimeter railways and Calorimeter installation/service equipment) & Calorimeter cooling system. • Instrumentation of Photon Calorimeter - Calorimeter High-Voltage control system, Calorimeter LV power supply system, Calorimeter “cosmic-ray” Pre-calibration System, Calorimeter Monitoring/Calibration System, Calorimeter WFD-readout System. • The cable system of Photon Calorimeter– 3,172 signal cables, 2704 HV control cables & 2704 3 LV power supply cables.

  4. Cost estimation for Calorimeter System *) Support of the FTE scientists: KOPIO - $1,069k, IHEP - $359k, YALE - $976k. **) IHEP contribution in past: Scintillator factory (~$3,000k), Test facility (~$200k).

  5. Calorimeter mockup production *) Production cost of Calorimeter mockup is $313k. Support of the FTE scientists for study of Calorimeter mockup performance is $191k (Yale – $145k, KOPIO – $46k).

  6. Photon Calorimeter production *) IHEP support of the FTE scientists for supervision and tests of modules, APD-units & APD-instrumented modules is $359k.

  7. Cost of the module production The module’s design includes 15 assembling details Module’s production rate is 6 modules/shift

  8. Cost of the module instrumentation Preamp APD LV - HV Cost of the module’s instrumentation (APD) Quoted price of the LV-HV Model: C20 Quantity: 2,500 Unit Price: $ 79.00 John Bianchi EMCO High Voltage Corp.11126 Ridge RoadSutter Creek, CA 95685, USAPhone: (209) 223-3626www.emcohighvoltage.com Quoted price of APD Model: SD630-70-74-510 Quantity: 3,000 Unit Price: $ 425.00 Paul Sharman Advanced Photonix, Inc.1240 Avenida Acaso Camarillo, CA 93012, USAPhone: (805) 987-0146www.advancedphotonix.com Module’s instrumentation rate is 6 units/shift

  9. Cost of the module instrumentation Cost of the module’s instrumentation (PMT) • Requirement for the PMT instrumentation is the low magnetic field (< 100 Gauss) into the PMT-location volume • Cost economy is $230k (~ 3% of the total cost) • Energy resolution will be 3.5%/E, instead 3.0%/E Module’s instrumentation rate is 6 units/shift

  10. Calorimeter instrumentation HV control systemfor control of APD HV-units. System includes 2704 programmable D-A VME converters. A base unit is a commercial 12-bits D/A converter (XIP-TVME200/XIP-5220, produced by Xycom Automation Inc.). The production cost per channel is ~ $72. “Cosmic-ray” pre-calibration systemfor adjustment of APD HV, a Calorimeter pre-calibration (accuracy better than 4%) and online long-term monitoring of the APD gain (accuracy better than 1%).System is based on detection of signals from the “cosmic-ray muons”, vertically traversing Calorimeter modules, and includes 468 programmableLow-Threshold Discriminator & Trigger Programmable Logic. A base units are the commercial LTD & TPL (V814 & V495, produced by CAEN). The production cost per channel is ~ $69. Monitoring-calibration systemfor online short-term monitoring of the APD gain & timing. System is based on the "ultrabright LED-lamps" with an electronic method of stabilization of the light output and includes 44 special LED modules. The similar system has been developed and tested for LHCb project. We propose to adapt the LHCb system for our project. The production cost per channel is ~ $63. Calorimeter readout electronicsinclude 176 WFDs boards and 12 crate-collector boards. The production cost per channel is ~ $301.
