RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli RPC DCS Status I.N.F.N. Naples The PVSS-DCS prototype has been developed by G. Polese and P. Paolucci and extensively tested at CERN during the JCOP-DCS month dedicated to the RPC (feb 05) RPC muon System for DCS is developed in the form of a hierarchy where every object is represented as a node of the tree, following CMS structure. Its architecture has been developed using the framework components. Naming and color framework conventions are respected !! Alarm conditions on HV and LV devices have been set and each channel has a summary alarm. It will be shown in the next slides. A first XDAQ-DCS for the Front-End is ready from June 2005 (Warsaw) 11/16/2018 RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli

RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli Temperature sensor I.N.F.N. Naples Our goal is to measure the iron gap temperature with a precision of 1oC in order to: compensate the HV working point in case of a large gradient of the temperature e/o atmospheric pressure; study the RPC aging and the current/noise behaviors taking into account this crucial parameter; Switch off the chamber/sector/wheel in case of “high” temperature. We have decided to use the Analog Device AD592BN transducer, after having tested different sensors. AD592 temperature transducer High Pre-calibrated Accuracy: 0.5oC max @ +25oC Excellent Linearity: 0.158C max (0oC to +70oC) Wide Operating Temperature Range: –25oC to +105oC Single Supply Operation: +4 V to +30 V Excellent Repeatability and Stability High Level Output: 1 mA/K Two Terminal Monolithic IC: Temperature In/Current Out Minimal Self-Heating Errors 11/16/2018 RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N.

RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli Gas Control Project I.N.F.N. Naples Experiment Gas Systems have a common implementation (provided by CERN Gas Group & JCOP) All the sub-detector Gas Control Systems are supervised by a single PVSS system (redundancy is foreseen) All gas parameters are made available to Central DCS or Sub-detector DCSs. Sub-detector panels may display any gas parameters. These panels will not allow any actions. All actions must be performed from the Gas System panels. Pannels in the Gas System will be developed and maintained by the GCS team. These can be accessed from any DCS station. Actions can be performed by shift operator and/or sub-detector gas expert (different users have different permissions) A central gas support team, including piquet service, will be provided for all the experiments.

RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli Front End Board I I.N.F.N. Naples The front end electronic boards communicate with the Link Board through the I2C bus; Each Slave LB receives data from up to 6 FEBs  96 strips; Each Master LB is connected to, not more, than 2 SLB; MLB transmits data to the control room via optical fiber; Each LB crate house up to 8 LBs and has 1 Control Board (CCU); The RPC continuous monitoring (noise rate, occupancy…) will have a refresh rate of 10 sec; For each strip the events before and after windowing are counted during a defined period of time. That allows plotting of rates and efficiency; There are two 32-bit counters for each group of 128 channels/strips; The amount of data to be sent is 2*32*128 = 8 Kb/10s/LB/plot. 11/16/2018 RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N.

RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli Front End Board II I.N.F.N. Naples The theoretical throughput of a CCU chain (up to 27 CBs) is 4 MB/s. The theoretical throughput of a LB box is 4 MB/s / 27 = 152 KB/s. The theoretical throughput of a Link Board is 152 KB/s / 8 = 19 KB/s. Required throughput for a continuous monitoring of one RPC is: 128 strips * 2 counters * 32 bits = 8 Kb/10s = 100 Bytes/s. The I2C communication does not contribute significantly to the total CCU load. The total bandwidth depends on the number of CB's in single CCU chain (serviced by a single FEC). 11/16/2018 RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli

RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli Conclusion I.N.F.N. Naples The PVSS and XDAQ prototype are working and they will be tested extensively during the Cosmic Challenge The temperature readout has to be included in the PVSS proto The massive control of the FEB has to be tested in XDAQ Final state machine and other tools (alarm handling, logfile…) will be certainly improved after the Cosmic Challenge test and with new version of JCOP. Massive configuration and DB interface has to be tested as soon as possible. The interface between PVSS, XDAQ and RCS has to be developed and tested for middle 2006. 11/16/2018 RPC Manufacturing Review - Pierluigi Paolucci - I.N.F.N. Napoli
