1. MobiDick4 progress report Carlos Solans

2. Introduction MobiDICK is a complete test bench for super-drawers Will be used during the maintenance in the long shutdown of 2013 Present system (MobiDICK3) based on: VME crate VME boards (ADC, CPU,…) Aluminum box: 50 cm x 33 cm x 41 cm and 20kg Why MobiDICK4? Now there are only 3 systems available, we need a fourth one to test 4 barrels at the same time… No replacement for some modules (CPU) Obsolete technology Reduce size and weight Expand compatibility with the new front-end electronics (Upgrade demonstrator) MobiDick42 Carlos Solans Old MobiDick

Firmware: Linux 2.6.39 Easier maintenance and support Drivers for Xilinx PowerPC @400MHz!! Crosscompiling tools: ELDK 5.1 (www.denx.de)www.denx.de VHDL Control for hardware devices MobiDick45 Carlos Solans

6. Embedded system MobiDick46 Carlos Solans

7. Trigger board Specifications Two ADCs in each board: ADS5271 Local oscillator (for prototype) with clock buffer to feed both ADCs Output connector to mainboard: WE part no 6130xx21821 Trigger cable connectors for box (scem 09.21.21.130.5) Production Version 1: 2 boards (1 dead) Version 2: bug fixes Firmware Working on communication protocol with mainboard Registers 1 FIFO mem per channel 1 config per ADC MobiDick4 Carlos Solans 7

8. Glue software MobiDick software is divided into front-end (Willy) and back-end (server) Server cross-compiled for the motherboard (ppc) Replaced hardware calls by new hardware libraries Status: Hardware library prototypes ready, new package m4_server Repository: https://svnweb.cern.ch/trac/ificuwrepo/browser/MobiDick4/https://svnweb.cern.ch/trac/ificuwrepo/browser/MobiDick4/ Work distribution: Digital, trigger, LED: Gang CAN, HV: Vinicius Installation cross-compiler tool at CERN: Fernando MobiDick48 Carlos Solans Willy Server Mobi DICK Linux pc ML507 power pc Compiled in linux, executed on linux Special EDK required, can only be executed on the board

9. LED + HV driver Responsible Michel Crouau from Clermont Ferrand Cost estimate is 1100 € Communication with main board: HV CTRL: TTL level for an ON/OFF relay. LED CTRL: ECL level for LED trigger.

12. Power supply board Common power supply board Provide +12V, -12V, +5V, -5V, +24V List of components bought through EDH Schematics done (Fernando) Layout done (Alberto) PCB produced at IFIC Mounting (Fernando) Found a component with wrong pinout (-5V) MobiDick412 Carlos Solans

13. MB CANBus We need two can bus interfaces Implement CAN communication via serial port RS232 Commercial dongle exists to transform to CAN protocol Cost: 79 EUR Already bought Output of dongle has to be transformed to DB15 standard Connector (Vinicius) Documentation http://www.aggsoft.com/rs232-pinout- cable/modem-db9-to-db15.htm Need powering from the CAN side MobiDick413 Carlos Solans COMCOM Dongl e Super-drawer DB15 DB9 Power

14. Mechanics, cabling and assembly The system is enclosed in a box of size (20 x 15) cm Patch panel provides connectors for short cables to super- drawers Trigger cable: EDH 09.21.21.130.5 Canbus: Custom provided by Vinicius MobiDick414 Carlos Solans To super- drawer From canbus dongles

15. Collaborations Collaboration with LIP (Jose Augusto) They want to participate in the implementation of the ethernet. Collaboration with UTA (Giulio Usai) Still no news Collaboration with Stockholm (Christian Bohm) In stand by MobiDick4 Carlos Solans 15

16. Publication We submitted an abstract and summary for TWEPP-12 conference in Oxford (17 - 21 September) https://indico.cern.ch/abstractDisplay.py?abstractId=28&confId=17059 5 https://indico.cern.ch/abstractDisplay.py?abstractId=28&confId=17059 5 MobiDick416 Carlos Solans
