PCBs FSU (12 persons)

• An overview will be presented by Julien Burnens

• STD PCB’s , advanced PCB’s , Flexes but also STD GEM and STD Micromegas detectors

• The activity can be regulated by subcontracting STD PCBs

• The Knowledge is not absolutely CERN Specific for STD PCB’s

29/11/2012

MPGDs activity (4 staffs)• Prototyping GEM foils and recently GEM detectors

– Large application domain (Compass, Totem, LHC-B,CMS, Alice etc…)– R&D on simplifying assembly– R&D on 2m x 0.61m GEMs

• Prototyping Micromegas detectors– Bulk Micromegas (General purpose)– Resistive protections (large sizes HIP detectors)– Micro Bulk Micromegas (Rare events ex: CAST)– R&D on fast high granularity detectors– R&D on 2mx1m detectors

• Prototyping Thgem– Cherenkov detectors , Liquid Ar detectors– UV or light detectors– R&D on ramping up in size and stabilizing parameters

• Prototyping Resistive MSGCs– R&D on the principle

• Examples will be presented by Olivier Pizzirusso• All these technologies are CERN Specific• Some projects need medium to high volume production (CMS, ALICE ,

LHC-B, ATLAS)• There is real possibilities for subcontracting but we will be surely

involved in large volume starting phase productions in 201429/11/2012

Conception in MPGD(staff and leader task)

• PMT do the conception of the Spark resistive protection system in some detectors taking in account:– Granularity– Rate– Energy resolution– Dynamic range of primary ionisation – Detector size and quantities.

• PMT have done the full design of some detector (growing activity).

• limited layout service (R&D purpose only) for:– Simple modification– Repetitive patterns– MPGD Detectors in R&D phase– Mechanical parts

• For problems exceeding our Physics competences we are in close contact with different physicist ex:– Leszek Ropelewski for all MPGD type (CERN)– Joerg Wotchack for Resistive Bulk detectors (CERN)– Iannis Geomataris for Rare event detectors (Saclay)– Vladimir Peskov for new exotic structures (CERN)– Silvia Dallatorre for THGEM (INFN)

Special components prototyping and R&D (3 staffs)

• Low mass circuits– Aluminium tracks, thin dielectrics, thin copper– NEW! Embedded silicon active devices

• Exotic heat-sinks– High thermal conductivity Carbone composite (epoxy or carbon matrix with carbon fibres)– High thermal conductivity graphite (PG , TPG)– Test on Diamond

• Fine line single side or multilayer circuits– High resolution interconnect down to 15um line and space on large single side flexes– MCM-L, MCM-D, MCM-C and MCM-S– Pitch adaptors– Embedded pitch adaptors in PCB

• Cryogenic devices– Flexes cables– Capacitors– Heaters

• Mineral substrates– Thick film (vacuum, high temp, high power applications)– Thin film (pitch adaptors on Glass)

• Exotic material etching– NEW ! NbTi sensors– Lead converters– Tungsten, Titanium Milling

• 3D Polymer micro structures– NEW ! Low mass cooling devices for Inner tracker detectors (Micro channels)– Special Pillars for gas detectors

• Radiation tolerant interconnect circuits up to 250 MRad

• Some examples will be presented by Antonio Teixeira• Most of these technologies are CERN specific• Subcontracting is an issue (no mass productions)• Some projects needs medium size productions ( ex: IBL ATLAS consuming R&D resources)29/11/2012

Contact with Industry (leader task)

• Know how transfer and advice on MPGD production:– Companies :

• ELTOS resistive Bulk Micromegas 10cm x10cm OK 1m x 0.5m in progress• ELVIA resistive Bulk Micromegas 10cm x10cm OK• TECH-ECH GEM 40cm x40cm OK 1.4m x 0.6m in progress• TECHTRA 10cm x 10cm OK• NEW-FLEX stopped

– Know how transfer on:• Resistive materials• Kapton etching on large size GEM• Ultra cleaning

• Study the level of price of standard PCB in industry.– To adjust CERN internal algorithm for PCB price calculation. (Comparison done

with companies having similar activity in western Europe)

• Auditing companies – In order to select 2 of them for CERN main PCB subcontracting contract renewed

every 5 years.– To keep an eye on equipment and technology evolutions

29/11/2012

Future• Maintaining knowledge on the latest interconnection technologies

• Based on the existing equipment pursue the development of specific technologies needed for HIP

• Pursue the technology transfer to companies for large volumes productions in order to focus our resources on R&D and prototyping

• Maintain the STD PCB activity to stabilize the work-load and maintain the equipment operational for MPGDs and special components prototyping.

• In special cases with appropriate agreements participate to medium or mass production
