• Our activities have been focused on: – Weak points characterization of old FEE:Impact for Upgrades

designs– Evaluation of new powering schemes– FEE characterization old TRACKER: Coupling Mechanisms– Project proposal preparation in collaboration with IFCA

• Noise immunity of CMS Tracker upgrade



2. ITA activities 2008 & 2009 for HEP• ITA has been a member of CMS tracker power

task force– Review status and plans for DC-DC conversion

systems and Serial Powering systems: Advantages and Dis-Advantages of both systems

• Nov. 08 & Jan. 09 – 5 meetings at CERN

• Members: Peter Sharp (chair), Fernando Arteche, Guido Dirkes, Federico Faccio,Lutz Feld, Frank Hartmann, Roland Horisberger, Marvin Johnson, Katja Klein,Alessandro Marchioro, Beat Meier, Mark Raymond.

– ITA has been in charge of the study of the noise issues of new powering scheme :

• EMC emissions of DC-DC converters• EMC Issues in DC-DC & serial powering schemes

• All these activities have been founded by ITA



2. ITA activities 2008 & 2009 for HEP• Upgrade meetings – 3 Contributions

2. ITA activities 2008 & 2009 for HEP• Collaborations

– SLAC• EMC studies for experiments upgrades (SLHC)• Proposal preparation (some common parts)• Several papers

– IFCA• R&D project for National research program:

– I+D en detectores y estudios fenomenológicos para el Colisionador Lineal Internacional” (Ref. FPA - 2007- 66387)

• R&D project for CMS upgrade– EMC issues for Tracker Upgrade

• 1 paper

– Universidad de Santiago - IGFAE• Very recent discussion • Collaboration in EMC issues for Belle II



3. R&D project for SLHC : Motivation• Tracker upgrade has decided to establish an EMC strategy to

ensure the compatibility of electronics system– CMS Tracker power task force has identified EM noise as one of

main stoppers

• Experienced gained in the past have showed that EMC studies may improve the FEE immunity to noise and minimize the commissioning– Fix design strategies– Fix integration strategies

• EMC based design has to be part of the experiment with similar importance that the mechanic / thermal design– They have to be analyzed and implemented together – It requires many EMC studies

• The EMC studies are focused on the tracker detector at the system level– To improve FEE immunity– To minimize EM noise levels within the tracker volume– To ensure the correct integration of SLHC tracker.



3. R&D project for SLHC: Description• EMC immunity studies for CMS tracker upgrade - 9.04

– IFCA & ITA – Approved by CMS MB on 20th of November• Long & detailed review process (Tracker & CMS upgrade MB )

– Proposal sent – 3 June

• Proposal was welcomed because covers a critical integration issue for the detector

• First R&D for SLHC focused on EMC issues

• First stage of the EMC strategy • The main goal of the project is:

– To define preliminary rules to ensure the integration of main components (Detector, FEE, Power network and DC-DC )

– To define design strategies that allow increasing the immunity of the Detector-FEE unit.

• It is divided in two parts:– Noise coupling mechanisms– New high immunity systems to EM noise



3. R&D project for SLHC: Working Packages • WP 1: Power network impedance characterization

– The aim of WP1 is to define and characterize the impedances connected to the DC-DC power converters

• It defines the emission (conducted and radiated) levels emitted by the DC-DC power converters compatible with the FEE immunity levels

– ITA will conduct this WP• Close collaboration with DC-DC group at CERN and Aachen group.

• WP 2: Noise propagation effects in power network– The aim of WP2 is to define the key points that allow designing the

power network to minimize the effects of noise currents generated by DC-DC coveters.

• PCB or Twisted pair cables

– ITA & IFCA will conduct this WP• Very close collaboration with FERMILAB- M.Johnson

– First prototype tested at ITA as reference institute



3. R&D project for SLHC: Working Packages• WP 3: Noise immunity test in FEE prototypes

– The aim WP3 is to define the FEE immunity on prototypes: Impact of integration strategies in the overall design.

• Conducted & radiated test (ITA facilities).

– ITA & IFCA will conduct this WP• Close collaboration with SLAC (ATLAS)

• WP 4: Validation of EM immune OFS for temperature, magnetic field and strain: Effect on overall EM noise– The purpose of WP4 seeks out the implementation of OFS to

substitutes previous measuring systems based on cooper cables and increase the immunity of tracker system.

• Different methods for attaching the fibres to carbon composites supports

• Architectures for sensor distribution network • EMC factor measurement

– Noise emissions and immunity with conventional electrical technologies versus Optical Fiber Sensors.

– IFCA will conduct this WP



4. Conclusions• ITA R&D activities for HEP experiments has been

presented – It is mainly focused on experiment upgrades

– It has been working during last 1.5 years

• ITA collaborates with several groups– IFCA

– SLAC

• ITA & IFCA project proposal has been approved by CMS upgrade MB– R&D project for CMS upgraded is focused on EMC issues

– First stage of long strategy to ensure the correct integration of Tracker upgrade

• It is possible to extend this work to other experiments– Belle II (recent discussion with IGFAE)
