Dear Manfred, in our opinion design requiremnts for Small Veto upgrade should be nearly same as it was for existing now SVETO. So why we make only preliminary cost-estimation for materials necessary to bild 10 new sc.counters (2 spare). With best wishes - Armen's, Samvel. =============================================================== Preliminary cost-estimation of materials for SVETO new 10 sc. counters (8 needed + 2 spare option): ----------------------------------------------------------------- Item amount price/ price piece (in DM) (in DM) ----------------------------------------------------------------- Scintilliators (6-10 mm thick, 45*50 cm**2) ...... 10 250 2500 Lightguides ....................... 10 150 1500 PM ................................ 10 500 5000 PM Bases .......................... 10 300 3000 Preamplifiers ......................10 100 1000 LED (calibration-check) ........... 10 50 500 Mecanical support-holder with possibility to keep, move in/out to/from position sc.counters ...... 1 2000 2000 ----------------------------------------------------------------- Total 15500 BICRON company available products price-list on Internet has been used for estimation. In fact, the prices for items are close to reality but not enough correct. For example: BC-408 plastic scintillator sheets with sizes 305 x 305 x 10 (5) mm cost 280 (255) DM/sheet; 2 inch PMT's EMI 9266KB04FL --- 370 DM/piece; 2 inch PMT's HTV R1306-01 ---- 630 DM/piece; We will try contact few companies for correct information. ------------------------------------------------------------------------ Samvel Ghazaryan Office: Geb. 2g-7 DESY - H1/Yerevan e-mail: kazarian@mail.desy.de Tel: 040-8998-2942 ------------------------------------------------------------------------
