  1. CMS RPC: update produzione, risultati tests ed analisi extracosti • Schedula • Test camere • Sito di Napoli • Sito di Pavia • ISR • GIF • DB • Aggiornamento costi Collaborazione CMS RPC Italia Gruppo I 12-13 Maggio 2003 Presentato da G. Iaselli

  2. CMS RPC production scheme Revised version Assumptions for phase I (end 2003/start 2004) Glossary • PV is devoted to chamber test only and to bakelite QC; • An additional external company (HT) will be involved in the assembly (under the control of NA group); • Gap production and quality control remains mainly with the BA group with some help from the NA group; • Chamber assembly at GT remains with the BA group only; • BA remains as chamber test site and an assembly sites for RB3 chambers in the first phase. PV Pavia INFN group NA Naples INFN group BA Bari INFN group GT General Tecnica (Frosinone) HT High Tech (Caserta) CERN CERN-ISR SO Sofia group PU Peking University group More assumption for phase II (2004/2005) • SO becomes an assembly and test site for RB3 in the phase 2; BA site can be considered as back site for RB3 assembly in case of difficulties; • RB1 chambers are built in Italy (GT) and tested at PV • A way to involve physicists from PU in the RB1 test should be envisaged; • RB2 are built at HT and tested at BA.

  3. RPC chambers production plan: phase I NA group is involved in the RB1/RB2 assembly at HT and the tests at BA PV group is involved in the test of chambers RB1 BAgroup is involved in the assembly and in the test at BA. BAgroup is also involved in the assembly at GT. CERN • Assembly BA + SO:28 RB3 GT: HT: 33 RB1 • Test BA +SO: 28 RB3 BA: 36 RB4 + 48 RB2 +6 RB4 (2500 mm) PV: 33 RB1 BA+NA: 13 RB2 + 6 RB4 Pavia Bari GT HT Napoli

  5. Gap production

  6. Double Gap production

  7. Chamber production

  8. Test set up in Bari • Efficiency • Cluster size • Noise rate • I-V dependense • Strip noise profile

  9. Results on RB2 Efficiency Cluster size Noise

  10. Global results Efficiency Cluster size Noise

  11. HT • Capannone disponibile (circa 250 m2 per un’altezza di 10 m.) • Tavolo di assemblaggio consegna prevista venerdì 9 maggio • Attrezzatura delle scaffalature e carro ponte in corso. • Entro la fine di maggio HT pronta ad assemblaggio pilota • Test previsti: • Leak test • Test di tenuta del sistema del sistema di cooling • Test di continuità delle strips • Con tester • Con frequenzimetro • Test schede di Front-end (corrente assorbita dalle FEBs) • Test HV • Correnti vs HV • Single rate vs HV

  12. HT Sistema HV Sistema LV Field point

  13. Pavia Trigger: HV e segnali cablati e funzionanti Logica di trigger funzionante  Gas: linee del gas pronte ma disponibili dalla prossima settimana. Distribuzione del gas delle linee interne testate e funzionanti. DAQ: a posto.

  14. Pavia Sistema gas Sistema HV trigger

  15. ISR • Test area • HV Test, cosmic test , DAQ. • Gas needed • RPC - DT Coupling • Labs • Tooling storage and working area + semi-clean room. • Pre-coupling storage • Basic validation tests • Current vs Voltage curves (mandatory) • Noisy strips (mandatory) • Dead strips (mandatory) • Efficiency vs Voltage • Single rate vs threshold

  16. ISR • Needed • Safety gas system 15000 CHF) • Gas distribution system 3000 CHF) • Set up of trigger system • DAQ/monitor/analysis system: • Signal cables (4 chambers) ~ 20000 CHF • HV/LV cables

  17. Data Base • It stores all the informations related to the construction of: • Bakelite • Single and Double Gap • Chambers • FE Electronics • …and all characteristics and testsperformed on these devices It is implemented in MySQL (the DB) and PHP/Javascript (the interface) It ispublic and completely WEB interfaced: You can read from everywhere You can write data from everywhere: GT, Bari, Pavia, Naples, CERN, etc. Just connect to: http://www.ba.infn.it/rpc • Advantagesof the choice MySQL/PHP: • They (both MySQL and PHP) are free • Very good performance (comparable to very expensive systems … ORACLE) • It was the first Construction DB available in CMS: • Very good interface, developed at home • Graphic possibility to display and compare data: efficiency, currents,… • Tools for production coordination • Summary tables

  18. GIF 4 Gap (50x50 cm2) under irradiation since June 3 Gap (50x50 cm2) with “new” bakelite under irradiation since September 2 RB1 under irradiation since January We are continuously monitoring with and without Gamma SOURCE Currents Rates Efficiency Fast Charge Small gaps RB1 Rate: 30 Hz/cm2 (safety factor included) Average total charge: 30 pC Effective operation time: 5x107 s (10 LHC years) The total expected charge is be 5 10-2 C/cm2

  19. Accumulated charge Small gaps ”old bakelite”, 7 CMS years Small gaps ”new bakelite”, 4 CMS years RB1 We expect to reach the barrel limit in the summer for the small gap and at the beginning of next year for RB1

  20. Small gaps BEAM PERIOD 2002 OLD bakelite ABS1  200 Hz/cm2 Average Efficiency ABS1 Source OFF Efficiency at plateau DEff at plateau  0.6 %

  21. Small gaps Shutdown Period 2002/2003 TEST with water Old bakelite RPC #9 never irradiated!! High gas flux rate: # volume 17 103 expected in CMS: # 5 103 Possible change of resistivity!! New bakelite Efficiency and rate capability is restored with “wet” mixture

  22. RB1 counting rate at different test periods @ ABS1 ABS1  200 Hz/cm2 currents at different test periods @ ABS1

  23. RB1 Comment Activity at GIF (+ test beams) is taking an increasing amount of financial and manpower resources in conflict with other major activities (production and tests at assembling sites, ISR) The close loop gas system will be in operation this week. A detailed study of the aging effect due to some polluting compound in the gas mixture has to be carried on.
