2. Scientific issues• ITAINNOVA - EMC facilities allow to perform
Electromagnetic Compatibility Test .– Non–standard test (Specially focused on HEP)– Standard ( According to European Directive 2004/108/EC)
• These tests may be used to define in any electronic device installed in HEP experiment:– EM noise emission level (noise emission test)
• Conducted• Radiated
– EM noise immunity level (noise injection test)• RF conducted and radiated noise• Transients test

• What ´s the purpose of these tests ? • What is the information that can be obtained once the
data is processed?....• These tests are very good for:
– Grounding topologies evaluation• Diagnosis
– FEE designs• Detection of sensitive areas • FEE frequency response to noise
– Noise distributions – EM mapping• Conducted or radiated
– Filter designs– Noise emission specification from PS

![Page 15: ITAINNOVA TA: Scientific & Administrative issues Electromagnetic Compatibility Facility for electronics noise and grounding diagnostics (WP12 – Task 12.2)](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc75503460f94abbf73/html5/thumbnails/15.jpg)
3. Administrative issues• ITA offers the possibility to perform any EMC test for a period
of 5 weeks per year.• Access duration:
– Standard access (components) : Less than 1 week– Extended access (large systems) 2 - 3 weeks.
• Users are expected to request the access a few months in advance and to have a technical discussion about its specific needs prior to the access (Follow the official TA procedure)• On site review is very recommended - 1 day meeting !!!!
• Users are expected to be present at ITA during the tests while ITA engineers will operate the testing equipment of the facility – It is possible to ask for a remote access – It is mainly focused on
EMC directive tests or PS noise emissions tests.

• HEPHY institute (from Vienna) has requested an access– Extended access - Full EMC characterization of SVD
prototype for Belle II (2 weeks) – Visitors – It is completed– Standard access (3 days) – Conducted noise emissions of DC-
DC converters – Remote access – End of June• We spent one day in Vienna designing the test campaign
– Very useful (a month in advance)• The test campaign was very useful - It finished last Monday
– 70 GB of data – More than 500 measurements– 10-12 working hours per day (for two weeks)
• This is the first time that a HEP detector has been characterized in a semi-anechoic chamber.
