Presentations:
=============
The meeting presentations have been combined into PDF files which were
put into the EMI Elogbook:

1. EPAC06 Poster & Proceedings:
   FEL Disturbance by Ambient Magnetic Field Changes (Herbert Kapitza)
2. Simulation von Modulatoren mit Pulskabeln
   unter besonderer Beachtung des EMV-Verhaltens     (Narcisse Ngada)
3. Allgemeine Erdungsempfehlung - DEF       (Brüel & Kjaer Vibro GmbH)

Comments:
========
0. It was requested to limit the meeting to one hour: 11:00-12:00. We will
   try this (only one major presentation per meeting) and as a compensation
   have the meeting more often, say every 4 weeks.

1. A poster on "FEL Disturbance by Ambient Magnetic Field Changes" (i.e. the
   influence of PETRA proton ramps on SASE in FLASH) was presented at the
   EPAC06 in Edinburgh.

2. The comment was given that differential pulse cables would be best, but
   difficult to put into practice.

3. AOB:
   - S.Schrader and R.Saust directed attention to a trilingual paper
     distributed by Brüel & Kjaer Vibro GmbH:
     D: Allgemeine Erdungsempfehlung
     E: General Grounding Recommendation
     F: Recommandations générales des mise ŕ la terre
   - Just as a reminder: All material presented in this meeting is accessible
     through the TTF Elogbook:
