2 TEC Petal Pilot Centres Last year TEC established two pilot centres for petal production Lyon took the responsibility for the assembly part of the petal production, which includes Definition of assembly sequence and material needed Development of a computer aided assembly program Development of hardware parts (HV check PCB) Karlsruhe took the responsibility for petal testing in a long term setup, which includes Definition of the test strategy and material needed Development of missing parts in strong collaboration with Strasbourg and Louvian Software development, based on modul lt software. Coordinated by Wim Beaumont (Antwerpen, Karlsruhe and US mainly) Tracker Week October 2004 Guido Dirkes 2

3 Karlsruhe petal pilot centre LLN cooling plant (outside) LT setup Assembly storage Assembly setup ARCS system 30 m² Clean room class Tracker Week October 2004 Guido Dirkes 3

4 ARCS setup Before assembly each module will be ARCS tested, including a LED pinhole search Tracker Week October 2004 Guido Dirkes 4

5 Assembly bench Contorl ring LV PS Delphi PS to run one power group VME crate for ofed with one OEC KA omux Tracker Week October 2004 Guido Dirkes 5

6 Control ring cable Petal Side We use a patch panel for the petals, which comes with a Sub-D 25 pins connector for the control ring (RWTH Aachen) Petal patch panel Replaced large FECadapter by an adapted version for our needs FEC board (CERN) TEC replacement Tracker Week October 2004 Guido Dirkes 6

7 Small parts Responsibilities for the distribution of all the different small parts defined 7 types of screws 2 types of wells 9 types of distance plates 7 types of bridges 4 types of peak bushes 2 types of fiber clamps 13 types of AOHs CCUMs Tracker Week October 2004 Guido Dirkes 7

12 LT setup Dry LLN air cooling cooling plant (outside) liquid industrial fridge Lieberherr distributed and modified by Strasbourg electronics rack Tracker Week October 2004 Guido Dirkes 12

13 Lt setup Behind the fridge and rack is the operator placed. Two PC are used in the Lt setup: one slow control PC runs power supplies, controls frigde & cooling plant, reads interlock one DAQ PC control slow control v TCP/IP Tracker Week October 2004 Guido Dirkes 13

14 Lt hardware LLN Interlock board Iseg HV power supply Lambda LV power supply Tracker Week October 2004 Guido Dirkes 14

15 Lt hardware Karlsruhe omux system Tracker Week October 2004 Guido Dirkes 15

16 HV switching MSC HV LV Control 6 HV groups (HV channels) each group has four lines on the Multi Service Cables (MSC) current resolution of the HV supplies is not sufficient develop a HV switching matrix board, switch individual lines on / off measure currents with 10 na resolution merge LV and HV to MSC Tracker Week October 2004 Guido Dirkes 16

17 DAQ software Tracker Week October 2004 Guido Dirkes 17

18 Software progress / DAQ All parts are working, which include Optoscan runs (~12 min) Time tune runs (~5 min) Ped runs (~7 min per APV mode) Cal profile runs (1.5 h per APV mode) IV runs (2 h / to be optimised! Expect 8-12min finally) Latency runs (2 h peak inv on) Scenarios working Problems: occasionally crashes, header finding errors and I2c problems / TOB affected as well Tracker Week October 2004 Guido Dirkes 18

19 Slow Control Labview interface done by Louvain Tracker Week October 2004 Guido Dirkes 19

20 Slow control Slow control runs Fridge (1) RS232 LLN Cooling plant (1) RS232 TRHX (1) RS232 HV switching matrix RS232 Lambda power supplies (6) RS232 HV power supply (6 ch) iseg, CAEN supported CAN-bus Interlock box PC-DIO card Acts as server for DAQ. All measurements can be read form DAQ side Tracker Week October 2004 Guido Dirkes 20

21 Software progress / Slow control Except for the HV switching matrix control all functionalities are implemented Problems after an interlock action detected for the LV control IV curve routine has to be optimised transmission of interlock status to the DAQ to be added Tracker Week October 2004 Guido Dirkes 21
